Dave, my tank is green !
It's a 55 gal, and I replaced 25 gal and a huge cleaning.
afterwards it got foggie then cloudie now it's green.
I took water samples 3 times to the store. Every time they said it was fine ! And that it will go away , they say I over cleaned it and replaced way 2 much water! And maybe I "awoke" something
It's been well over 45 days now and I can't even see the fish.
I think I will start over again , I only have a few 5-6 inch fish anyhow.
