Scuds for green water is still my favorite method for a few years now. Works like a charm on a small scale: 2 no-plant scud vases on my windowsill with old tank water gives me green water all year to feed my small daphnia cultures.

[@chevyfish5373]

I am a true believer in greenwater and have been so for decades. I have never used scuds though. I use mystery snails and light. I find my healthiest most productive tanks are my greenwater tanks. It is so satisfying to see little fat bellied fry darting around and knowing they are well fed. Thanks for putting the word out. One thing to get rid of greenwater is daphnia. They quickly make short work of greenwater and provide a good source of food in and of themselves for fry and adult fish alike. Love your videos and your quest to do the hobby justice. Keep up the great work. I wish you good luck in your fish warehouse endeavors.

[@DansFish]

Great point about daphnia clearing up green water!

[@sharonjack7239]

I put some rams-horn snails, pond snails and mystery snails in a clear plastic container in a sunlit window. Gorgeous green water within several weeks. I do feed the snails some raw spinach and fish food. When summer comes, I will make sure they do not get too hot in the window. Thanks for a helpful video!! USA

Awesome How to Greenwater, Dan, Thanks. I have a 3 foot tank outside with very healthy Golden Comets, some Ramshorn snails, and Vallisneria and AFTERNOON SUN. This Tank has also developed a Blackworm Farm in it's substrate. Green water and blackworms have been fed to all my fry for years. Such an Underappreciated Resource. Today I will celebrate this tank......might even make a video of it, haha.

I threw some Dalmatian Mollies into a back porch swimming pool filled with dwarf water lettuce this summer. After a few weeks it went green. By the end of the summer the survivors (dang dragonfly larva...) were three times larger than the tank raised ones from the same batch. Green water for the win!

I fertilize aquarium or pond water with macro and micro ferts. Add snail and feed the snails whatever veg.

[@CaylorsReptilesAquatics]

I dont have scuds. I had a tank make itself green water. A ten gallon with Rich Fish from Pam, Shrimp from Chattanooga Ed, and IFGA Guppy fry from Rick with BamAquatics. I do 50% water changes weekly and the water stays dark green. I started with some plants from Rachel O'Leary, and Ed, so I've left them in. This has been going maybe two months and all are growing and multiplying. Great Green Water Vid. Thanks Dan.

[@DuzzyDobbin]

Hi mate, great topic, where or how do I start a scud culture to go in green water? Regards Duzzy from 🇦🇺

[@DansFish]

Not sure where you can get scuds in AU. I got mine on Ebay a long time ago. If you can't purchase any, you may be able to find some under the rocks in your local creek and go from there.

[@heatherjewett2912]

Hey Dan, do you have recommendation on a specific light brand for your greenwater? Do you use Beamswork, Finnex? Thanks!

[@kkutube1972]

It is my first time trying to culture green water. What I found out is, I can get green water in 24-30 hours with white light on all the time and it need air bubbles.

[@angelberrios4990]

How well will green water work for Angel fish? I know brine shrimp are great for fry but green water seems like a more stable solution.

[@JoeCoffee9476]

Good video and great information. Do adult fish also benefit from green water, or would it be negligible once they can take larger foods?

[@DansFish]

I don't know of any commonly kept aquarium fish that would eat green water at an adult size. It would be great for filter feeders like clams and bamboo shrimp, but probably not so much for fish once they get a bit of size on them.

[@CarlosRodriguez-tb9by]

Can I use for corydoras fry? thanks great video

[@DansFish]

Sure, as a supplement. But, green water is free floating in the water column and cory fry need food on the substrate to get in a good feed.

[@pullbackbaby]

Do scuds eat heat algae? I'm doing this ASAP

[@hair_ofthedog5023]

My endler female/fry tank is an accidental green water tank. They grow so fast in there. Constantly cleaning the bottom of that tank tho!

[@tastyfishsauce4410]

Nice! I just started my scud culture for my pea puffer and the starter culture I got have green water already. I poured it to my 10 gallon bare bottom tank and has made the whole tank stay green. I guess I got lucky making instant green water lol. Now I'm trying to figure out how to clean the mulm without sucking my scuds out. Any ideas are welcome. Oh, forgot to mention its only been about a week.

[@DansFish]

One week and you already have the green stuff...that's great! When I siphon out the mulm in the scud tank, I run the water through a net with mesh large enough to catch the adult scuds, but not the mulm. Then, I swirl the water in the bucket with the mulm until the mulm is concentrated in the center. Then, I take a piece of repashy or other food and put it in the bucket towards the sides where there is the least amount of mulm. When the repashy is covered with the baby scuds that made it through the net, I scoop the chunk or repashy and the scuds out with a brine shrimp net and put them back in the culture. I don't save all the scuds this way, but I get a lot of them.

[@Chonsta]

i got a 3g black bucket outside w java moss and snails. the water is green!!! i didnt even know it was a food source hahaha

[@DansFish]

[@jcanales520]

Maybe I missed it but Where Do you get the scuds??

[@CrazyAquariumGuy]

With egeria Densa you would not even have that small amount of algae. But I have heard that Egeria Densa is forbidden in some states...

[@brandonlasvegas]

🙏😎

[@fieryjude]

I thought scud will devour java moss (any type of moss)? Or did you mean that you use the scud to clean the algae off your java moss, then remove the moss from your scud/green water tank? Also, you said there will be plenty of nutrients in the tank to make green water - are these nutrients just what's produced as waste from the scuds, or are you adding from another source like fertilizer? Thanks, Dan!

[@dianaconner4469]

Is green water thick? I have a large vase with a couple shrimp and a nerite snail. There is a dense cloud of green... when I drop in sinking food, I have to push it through the cloud. I’ve noticed my shrimp grazing on the bottom of the cloud. Is this green water or some other type of algae? I have a tank with endlers that are expecting. Just trying to be ready with healthy food for the little ones. Thanks. Very interesting video.

[@DansFish]

Greenwater is not typically thick. What is probably happening is an infestation of some kind of thick surface growing algae. It is fine for a while but, if it gets too thick, it could hamper O2 exchange at the surface.

[@MELODYMUNRO]

My goldfish pond has gone green - can I use that to feed my fry? is that the same stuff?

[@Xenofan20]

It is

[@anotherthez7598]

Good! What about the temperature? Can you keep the scuds with the Amano shrimp? Cheers :)

[@DansFish]

I just keep the tank at my normal fish room temps....mid 70s to low 80s. I've never tried to keep scuds with any shrimp. I think they would out compete the shrimp.

[@anotherthez7598]

@@DansFish Thanks :)

[@carbrickscity]

I get green water very easily. All I do is to put a tank outside under sunlight and the water would turn green in a few days, it would be faster if you have fish and feed the fish.

[@TimsBitsnPieces]

Hmmm very interesting.. not sure I want a whole tank dedicated to this culture tho... I guess it would be more for those that have an excess of 10+ tanks etc and could spare another tank just for this...

[@DansFish]

If you have small fry and limited space, you can do an infusoria culture in a jar. Be warned, however, that those jar cultures can smell pretty bad!

[@TimsBitsnPieces]

@@DansFish Thanks but No. haha..

[@Tomjarr1]

Green water cells alone are too small for fish to see and eat. It is actually the infusoria and paramecium that there eating. When eating the infusoria, the fry will take in some green water. That's how that works.

[@protaproy6785]

Can we make green water in indoor

[@MoreChannelNoise]

when you say scuds do you mean gammarus pule , or Mexican Gammarus (Hyalella azteca)

[@DansFish]

No idea which species I have. Whatever was on Ebay when I purchased them years ago.

[@raychill163]

can you have daphnia and scuds in the green water tank? Also one you get it how can you maintain it? Is green water the same thing as infusoria? Sorry if I misspelled that! Do you have a video on how to set up an ongoing supply of California black worms? Ok I'm just trying to stick with a few fish channels that are easy to understand for a laymen like me.

[@DansFish]

You can keep scuds in green water, but daphnia will eat all the green water in short order. In fact, daphnia is a great way to get rid of green water if you have it and don't want it. To maintain it, I just feed the tank and keep the light on. I change the water in the aquarium like I would in a normal fish tank and I run a sponge filter like I would in a normal fish tank. One nice thing about scuds is they keep the sponge filter very clean, so it does not get clogged up with particulates from the green water. I don't have a vid up on culturing blackworms yet...it is on the list to do. Hope that helps!

My green water attempts have changed from obviously green to more of a yellow with a hint of green. Any idea what this is indicative of? I've kept a jar of this yellow-green water for months with scuds hoping it would go back to green, but no luck.

[@DansFish]

My guess is that perhaps you are getting so much infusoria, that the green water is getting eaten by them. Infusoria, however, are also great fry food, so not really a problem.

[@FTFSupremacyROBLOX]

as unsightly as it is having a constant source of food should accelerate growth

[@CrowntailHalfmoon]

Hey Dan, Would love to see you actually drink that green water.Lol🤣 How long does it take to get green water? How many hours do you keep light on to get green water? If you can instead of dumping the green water from the tank in you automatically wc system i would keep a daphnia cultures and feed them the green water daily. This way you win win scenario as you can sustain green water and also get daphnia cultures to feed fishes. Maybe you can give it a try in a few 5 gallon buckets. Thanks for sharing your experience. 👍

[@DansFish]

Thanks for asking all the questions I should have covered in the vid, but didn't. 1. Once the plants are removed, the water gets green in a week or two 2. I keep the lights on roughly 14 hours a day If you drink it, I'll think about drinking it :)

I guess there are worse problems but I'm not used to dealing with algae anymore since I've got my methods figured out for the most part, and this is annoying.
