Has anyone had this problem?? How did you fix it?

WELCOME TO AA!!

Are you saying the water is all green, or is it on the sides/substrate/rock?
How old is your tank?
What are you water parameters? Ammonia, nitrItes, nitrAtes and phosphates?

[barett]

Yes, the water is all green. The sides and substrate are clean.
My tank is 2 months old. I have 16# of LR and 20 # of LS. Its a 20 gallon.
My Ammonia is 0, Nitrite is0, Nitrate is <10, and I dont have a phosphate test.
I was using tap water. Then about 3 weeks ago I switched to RO. Its getting better...but I cant stand the green lol.

You can run carbon in it, that should clear it up some. I would do a few PWCs with your RO as well.

[barett]

I do run carbon in it. I have been doin PWCs, 3 gallons with RO water.
It is less green and more white now.....but I cant get it any better.

[roka64]

Carbon works for about a week or so and after that will start to leach stuff back into the water. I use Purigen and love the stuff.

Black out your tank for a few days, keep the lights off and throw a sheet over it. That'll fix it. then you just have to try to fix your underlying excess nutrient problem.

if I black out my tank, will my anemone get hurt??

Sounds like it could be some free-floating algae. More PWC will be in order using a good quality RO/DI water. Also, you may want to test for PO4.
