    Hi have a question for ppl. I have a 90 gal with 20 sump haven't done water change in a move. When I did I did 30 gal as told to later find out only should have done a 10 at best. So the LFS said not to for a long time and gave me prime and stability. And at the same time I got the ick. So now I'm adding all that plus ick attack. Phosphate was 0.66 or little less ammonia was between 0.25 0.55. Ph 8.3 all other are o.i am using phosgrard. Now I have red and green algae the red is hair like. I've lost three high dollar fish. I don't know why they say not to
