Hi all, I have a question. I have a 50 gallon tropical tank, planted, with a variety of very small fish (think guppy size), some plecos, cory catfish, and mystery snails. I am having problems with the water just not staying clear. It's sort of a brownish fog, if that makes sense? I did recently (like last week) upgrade to a Cascade 100 filter with the spray bar to spread out the flow from the filter. Because I have all smaller fish, they were getting tossed around and stressed out with my last filter. I'm assuming that I may be experiencing a small bacterial bloom from the switch. Even after weekly 40% water changes, the color goes right back to the brown tint within a matter of hours. But would driftwood cause the brownish color? I have one good sized piece of driftwood, and one piece of mapano(?) wood in the tank, as well as all live plants (java fern, red wisteria, assorted anubis, and hornwort). Parameters have been perfect, although since changing the filter the ammonia rose a bit (read 1.0 today). Is there anything I can do about the color? Or do I just have to deal with it?
