I have a around 320 gal of water in my system. I think my water is clean enough to drink because my skimmer can handle a much larger system than mine. acans dont do well in my tank at all because of the water quality. i put in a fairly large rbta that was very bublby about a month a go i have a maroon clown that is close to the same size as it just a lil smaller but the nems tenticals are shrinking and the disk is starting to get lighter. i have 400w 20 k halides and my water perams are dead on and consistant any ideas? can the water be to clean?
