Watch at: 00:00 / 00:00:20Hey guys, this is Lei from Goldfish Corner.Welcome back!Today we're gonna talk about another interesting topic:How to create Green Carpet AlgaeSo about a year ago, I released a video to talk about two different types of algae in your goldfish tank,Watch at: 00:20 / 00:40which is green water and green carpet algae.I talked about the result and talked about maintenance,but I haven't talked about how to create the green carpet algaeI got a lot of feedback:"Hey Lei, could you please create anWatch at: 00:40 / 01:00educational video on how to create green carpet algae?"And I was so busyI kind of indulge myself into the goldfish culture and goldfish history side. So I released a lot of videosI didn't have time to pick up the green carpet algae until recentlyI post on my goldfish channel community. I post a survey.Watch at: 01:00 / 01:20I said: "Hey please vote the following topics."How to create a green card algae is on top.I hear you. And now I'm generating my answer to you.Here's another thing. That's why you need to subscribe my channel,and you have your chance to vote the future topicsWatch at: 01:20 / 01:40All the links are also included in the video descriptionPlease make sure you're gonna check it, because this video is actually more on of operation sideThere are a lot of links about products, about websites, about the tips.Let's go aheadSo before we talk about how to create the green carpet algae, my style is always "let's step back"Watch at: 01:40 / 02:00Let's look at what's are those common algae styles in your goldfish tankTo be honest with you, there are about 13 to 20 different types of algae in your goldfish tank,whether you see or not seeI'm not gonna go through all of these algae typesWatch at: 02:00 / 02:20but I gonna talk about probably 4 common algae styles in your tankSo the 1st one is very obvious - it's called a clear water. People called this as "Air Tank"because it just feels the goldfish swimming in the airif the water quality is so pure. There's no or less algaeWatch at: 02:20 / 02:40It is really gorgeous.What I call this is the beginners' dream tank.When I get into the goldfish keepingI want my goldfish tank looks like pure waterand very clean, crystal clear, just like this goldfish tank,which is beautiful, especiallyDuring the night, you turn off the ambient lightWatch at: 02:40 / 03:00and only keep the tank light. It is so beautifulThe water may or may not fully cycledJust keep in mind because there's no indicatorLet's see from the color or from the smellYou could fully or Not fully cycle waterOn the other hand, this may or may not be optimal for your fish tankWatch at: 03:00 / 03:20Let's wait to listen about the other options and you can make your choicesThe 2nd one is brown algae. The color is BrownIt's also called Diatoms or Silica Algae.It basically appears in a newly set up tank within one or three weeksWatch at: 03:20 / 03:40Your tank gonna go from the crystal-clear to this brown-coating color everywhere.Obviously, this is no harm to your goldfish, but it looks dirtySo many folks do not prefer brown algae style typeWatch at: 03:40 / 04:00but I want to share some interesting facts brown algae generates about 20-50% ofoxygen on the earth it also creates about half of organic material in the oceanSo brown algae actually contribute a lot without you knowing itThe 3rd one is what I called Green Water.Watch at: 04:00 / 04:20Green water is not a particular name of algae. It's just a styleA lot of tiny free-floating single-cell and just circling around the water. The water is purely greenIt's typically used in goldfish farms as you can see on this video,which is cropped from a documentarythat's a goldfish farm. It actually stabilizes water qualityWatch at: 04:20 / 04:40And the green water has a lot of nutritionsIf you look at my channel when I breed goldfish friesI intentionally keep them in the green water to keep the color and keep the water quality andalso help keep the fish growing fastObviously, it is not good for indoor fish tankWatch at: 04:40 / 05:00I guess you have the same feeling as mineIf you look at this picture you basically you don't see any fish as it's green everywhereSo green water fits for goldfish farms but doesn't fit for your indoor fish tankbecause if you have it you're not gonna see your fishSo the last one is actually today's superstar. The No. 4 style. I call it Green Carpet AlgaeWatch at: 05:00 / 05:20That's just a nickname. So a more formal name also known as Hair Algae. Just like shown on this pictureYou can almost see a grassland type of carpet algae on the bottom of your tank. It's so beautifulIt is best for indoor tankWatch at: 05:20 / 05:40particularly for the bare bottomObviously, you're not gonna have a sandy bottom.It's a bare bottom.The green carpet algae is gonna fit perfectlyAll the fish is so happy so vibrantIt's very colorful and you can see the algae actually not only give a better view but alsoWatch at: 05:40 / 06:00provide a lot of nutrition to the fishIt also stabilizes the water quality and also provides a clear viewSo green carpet algae plus clear water gives the best option in my opinion to your indoor fish tankThis is a kind of view when you see green carpet algae. If you don't see it, you're fineWatch at: 06:00 / 06:20You're like I want to have a clear water tank.But if you see it, you want it!All right. So if you want to create your own green carpet algae, please come with meWe're gonna go through every single stepActually from the theory, procedure, and also I'll share you one of the resultsWatch at: 06:20 / 06:40Please listen carefully make sure you understand everythingand then you don't have to ask me another question in the futureBecause you understand everything.All of this kind of knowledge or tips. You're not gonna see on any textbooksAt least I don't find any of this knowledge from the goldfish keeping textbooksI actually collected through my personal experience,Watch at: 06:40 / 07:00my friends experience and also some limited knowledge from online resourcesSo make sure you don't skip any of these.it's gonna be extremely helpfuland you're gonna make your dream come true to create your own green carpet algaeAlright, let's go with me. I like to talk about theoryI want to talk about a theory and then you can talk about an operationWatch at: 07:00 / 07:20The first thing let's talk aboutWhat is the condition to create brown algae?It's typically those four conditions:Low light, silicate, ammonium, and nitrate.So if you look at green water, what are the conditions for creating green water?Watch at: 07:20 / 07:40Ammonium, nitrate, carbon dioxide, and phosphate.So, let's seeWhat is the theory of the algae transition?So if you want to transition from brown algae to green water,you definitely need to switch low light to strong lightNatural sunlight is the best resourceIf you don't have natural sunlight, you need an LED lightWatch at: 07:40 / 08:00Not just a normal LED. You need a full spectrum LEDThe last one is you have to remove a silicate.Many of my friends asked meHey, I fight so hard against brown algaeI'm not able to convert from brown algae to green waterOne of the reasons is because you didn't remove silicatePlease make sure you do a water test to your tap water.Watch at: 08:00 / 08:20In many areas in the USA, some areas tend to have more percentage of silicate in the tap waterSo make sure you test it. Then remove itOkay, so that's the green water conditionLast one, let's look at what the conditions can generate green carpet algaeWatch at: 08:20 / 08:40You obviously have the condition of strong light and some of those componentsso what about the transition from the green water to green carpet?The first one you also need to maintain a strong light and remove silicateIn terms of ammonium & nitrate, you need to use strong filtrationWatch at: 08:40 / 09:00or increase your biofiltration to reduce ammonium and nitrateFor carbon dioxide and phosphate, you also need to reduce those twoSo how to reduce those two components?Aeration or adding air stones into the water to blow bubblesAlso, reduce the number of fishWatch at: 09:00 / 09:20Many times those, obviously, the high carbon dioxide, you have too many fish in your tankand do more frequent water changesOkay, let's check this picture again.So this is what I call a theory of Algae ManagementIf you know this picture, you can controlwhatever the algae you want to keep in your tank.Watch at: 09:20 / 09:40And the other thing is it shows the transitionSo the green carpet algae will not appear immediately in your newly set up a tankIt's gotta go through this procedureYou're gonna first have a sort of brown algae at the beginningand then brown algae by the certain conditions that you appliedWatch at: 09:40 / 10:00The brown algae is gonna become green waterand then from green water, you'll apply certain conditions,you're gonna get a green carpet algaeGreen water is the keyIf you don't have green water,you're not gonna have green carpet algaeLet me explain thisIf you only have strong light, no silicate, very low-level ammonium, and nitrate,Watch at: 10:00 / 10:20or very low-level carbon dioxide, or phosphate,you're still not able to create a great carpet algaeWhy?You are missing the seedsthe seeds of algae or the algae seedsSo all the algae seeds come from the green waterGreen water has a lot of seedsWatch at: 10:20 / 10:40and then you just killsome of the seeds that you don't like as green waterand you're gonna leave the algae seeds of the green carpet algaeRemember, write down this sentence"Green water is the key transition component to green carpet algae"If you're not able to generate green water, no green carpet algae is gonna come upWatch at: 10:40 / 11:00Alright, I know this is a little bit chemical stuffNow, let's go to the next page,which is more practical in terms of daily operationSo what do we need?Let's give a summaryand you probably can already get your list from the algae management theoryso first you need more than 8 hours of strong sunlightWatch at: 11:00 / 11:20However, if your tank is not facing the south of your house,or if you have a problem in getting sunlight,you can always use the full spectrum of LED lightCheck the links in my video descriptionI'm gonna list a few amazon links with the productthat I'm using in my tank that produces a good resultWatch at: 11:20 / 11:40The second one is the aeration of filtration.So aeration you need to get air bubblesThe why we need aeration is because you need to reduce the CO2 levelThe filtration, you also need a powerful filtration, is toreduce your nitrite and also reduce the ammonium levelWatch at: 11:40 / 12:00The Sump Filter is the best.If you don't have Sump Filter, on the top of the Trickle Box Filter is also a good optionWell, the third one is UV Sterilizer lightThere are many UV sterilizer lightsYou can go with any of the brands.Lots of my friends gonna ask me"Hey is a UV Sterilizer light gonna kill my healthy bacteria?"Watch at: 12:00 / 12:20"Is UV light gonna kill the algae, the green carpet algae?"The answer is No.Because the UV light is encapsulated within the chamber of the black housingSo the water basically is gonna come through the back inlet and throughWatch at: 12:20 / 12:40the UV sterilizer light bulb and come out of the UV sterilizer lightSo the UV sterilizer light is not gonna contaminate in outside waterIt's only gonna sterilize the water coming through the chamberSo this is a very good optionThe last one is fish wasteI'm not gonna ask you to collect a fish waste and dump into the tankWatch at: 12:40 / 13:00Simply what you can do is to put some fishSo if you have fancy goldfish, do not use your fancy goldfish as experimental material,but you get some common fish or some cheap goldfishPut them in your tankOkay. The other thing is your expectationThis is not a one-time dealWatch at: 13:00 / 13:20You're probably gonna need some iterationsI'm gonna tell you you're gonna failYou're probably gonna fail more than onceBut eventually, you'll make it if you follow my instructionBe prepared for the iterationsObviously, the last one is patienceIt takes timeIt's not like if you follow my setup, the next day your tank is gonna become green carpet algaeWatch at: 13:20 / 13:40It is anywhere from one week to one monthbut eventually, you'll get itNow you understand the theory of algae managementYou understand what you need to create a green carpet algaeThat's good. Let's look at thisI hope this flow chart will not blow up your mindWatch at: 13:40 / 14:00As an engineer, I want to put everything on paper with a flow chartSo it's gonna crystal clear to youand also you can follow the chart if there's a problemI'm gonna go through this with youBear with me. Deep breathThis is not something you can't understandIt's very simpleThe key component is green waterWatch at: 14:00 / 14:20You need to have green water and then everything becomes possibleSo obvious the first question isdo you have green water?If you have green water, jump to the next stepif you do not have green water, we need to create the green waterFor newly setup tanks just follow me. You need add fishYou need to add some lightNormally within one or two weeks, you're gonna see some brown algaeWatch at: 14:20 / 14:40The good news is very easy to remove brown algaeYou can just use your hands to scrub it offRemove most of the brown algae but not all of themMaybe leave 10% brown algae still on the tankWhy? Because you want to keep some algae seedsWatch at: 14:40 / 15:00You don't want to remove all the algaeIf you see brown algae, it also means your light intensity is not enoughYou're gonna increase your lightRemember you need a full spectrum LED light, OKIf you increase the intensity, you can use two full-spectrum LED lights or you can use longer timeWatch at: 15:00 / 15:20rather than 8 hours. You can use 9 or 10 hours.I'll also do a 50% water change right away.So with thattypically after about another weekMost of the brown algae should change back to the green waterIf you either get some green water from your poundWatch at: 15:20 / 15:40or you already generate the green waterand that is the possible stepNow everything is possibleOkay, so from green water, when you see your tankbecomes pure green, very thick greenAt this time, what you're gonna do is a 90% water changeWatch at: 15:40 / 16:00I also keep your strong light, 8+ hours strong lightand also put some air stones to get some air bubblesAt this moment, I don't know,Maybe your brown algae is so stubborn,If your brown algae come back, then go to hereas I said, very simple, just remove or scrab off your brown algae andWatch at: 16:00 / 16:19increase light, and do 50% water change, and just remove the brown algaeNormally, it should go back to the green waterOkay. So if no brown algae,Is the green water becomes thicker?if there's still thick green water everywhere,we're gonna do another trickWatch at: 16:19 / 16:40Remember this the trick gonna workWater change and then turn on your UV sterilizer lightand also remove some fishIf you have four fish, reduce by halfTypically, this is a very effective step to change the green water to green carpet algaeAt this moment, you probably already get green carpet algaeSo some of the friends may not need UV sterilizer lightWatch at: 16:40 / 17:00By using water change, you may reach from green water to green carpet algaeAnd some green water algae is so stubborn,you may need to put on the UV sterilizer lightBut eventually, bingle, That's your green carpet algaeThis big box is for daily or weekly maintenanceWatch at: 17:00 / 17:20Again, keep the strong lightskeep the strong filtration and aerationand also do a weekly water changeTurn on the UV light only if the green water comes backUV light sterilizer is a killer to the green waterbut use it as a minimum basisSo the last step is just to go back to my channelWatch at: 17:20 / 17:40and please comment to my goldfish channel on YouTubesaying: "hey Lei, your tips work. I get my green carpet algae!"Let me know and also, more importantly,let the community,let my friends on YouTube know your successSo the next stepI'm gonna give you one exampleThis is my friend in China, this is his tankWatch at: 17:40 / 18:00only takes him one week to get beautiful green carpet algaeBut he has a preconditionbecause he already has some green carpet algae seeds in his tankHe may have a different starting pointYou may start your tank from newly step up tank andThis example already has some green carpet algae grow on the bottomWatch at: 18:00 / 18:20It's just not as as beautiful as expectedThe second case is you can also check my caseIt actually shows on here from green water to green carpet algaeThe trick is just using the UV sterilizer lightOK, let's watch this videoWatch at: 18:20 / 18:40All right, so what do you thinkWatch at: 18:40 / 19:00You feel it's too complicatedWatch at: 19:00 / 19:20Something's so beautiful. You want to make itWatch at: 19:20 / 19:40Let me know your feedback, OKWatch at: 19:40 / 20:00and also if you like this video, please give me a big LIKEWatch at: 20:00 / 20:20Please sub my channel and feedback me what topics you want to hearWatch at: 20:20 / 20:40I also want to thank everyoneWatch at: 20:40 / 21:00because I read a statistic fact on YouTubeWatch at: 21:00 / 21:20It's typically every 100 views gives one LikeWatch at: 21:20 / 21:40But my Like percentage, it is always way beyond 1 out of 100 viewsWatch at: 21:40 / 22:00So thank you very much for all my friends that give me the positive feedbackWatch at: 22:00 / 22:20Big LikeWatch at: 22:20 / 22:40I'll see you next timeWatch at: 22:40 / 23:00Bye-bye

  1. Does anyone know a culture kit I can buy to start an algae bloom in my tank for my snails?

    I've tried methods where you put rocks in a container with water from the tank in a window, it hasn't worked, I've tried upping my light in the tank too and it won't work

    Tips are needed and welcomed

  2. I just want to give you 100 LIKES if it is possible to do. I just found this video while I am thinking about how to grow Green Carpet. I will try and will get back to you with the results. Thank you very much.

  3. I did an algea wall in my aquarium after the foam background I painstakingly crafted peeled off. I think the algea wall is great! And so do my fish, snails and nitrate levels. The green contrast really brings out the colour in my fish.
    Thanks for the video!!

  4. Hello Mr Lei, thanks for the very informative vids! I am new fans in goldfish keeping and dream to have green carpet algae. Subscribe your channel so I can learn more now. 🙂

    By the way, is the usage of fish salt will hinder the growth of green algae?

  5. Hi Hi.. thanks to your video i am now at dark green water phase.. should i do a 90% water change now? And will it instantly show green algae patches once i changed the water??

    Will green water overcompete the beneficial bacteria existing in my filter?

  6. hi Lei, thanks for the great video. One question that I have is what if we are starting from a mature tank that has brown algae already growing in it ?
    My tank is already matured for 6 months , with good filtration , with enough aeration and Full LED spectrum lighting. Keeping about 20 goldfishes in a 5×1.5×1.5ft glass tank. The fishes are fine but the issue is there is plenty of thick brown algae at the bottom of the tank while in noticed that the sides of the tank are having green algae growing. So my question is what I need to do in order to convert these unsightly brown algae at the bottom of the tank to green carpet algae ? . Should I create green water first ? If yes, how to create green water from a mature system that is already running on enough canister filtration (plus overhead trickle filter ) and with 4 feet Chihiros WRGBII ( On 8 hours /day) . thanks !

  7. Hi, nice video and thanks for this explanation. I want to grow algae for my sulawesi shrimps. I start my aquarium with Ro water and sulawesi salt. When i understand right, yo need silicate in the water for growing algae? But in Ro water is no silicate in it. My goal is not the green carpet algae, its more about a technical question.

  8. Hello i have a question. On my first attempt i grow green carpet algae but after few days brown algae mixed with the green algae. Then i reset and scrubbed all of the algae. Then after a few days only brown algae showed at the bottom, but on the sides green algae appeared. How can i grow green algae again at the bottom? I have 50 gallons tank with sunsun303b canister filter and a internal k1 canister then 25 watts of led light. I have 3 gold fish 2 medium and 1 juvi.
