cloudy water

[graber]

I HAVE A 180gal tank with about 15 diff fish all around 2-3inches,recently i have had problems with cloudy water and low ph. my tap water is very low on bicarb so i hve had to add chemicals to increase ph. my ph is now about 6.6 o ammonia o nitrites havent measured nitrates but last time was low. tank has been setup for 4 mounths.i do biweekly 30 water changes . any suggestions?

Sounds like you may have some uneaten food trapped somewhere. I would do an indepth search through the tank and make sure you don't have some plant matter or decaying food somewhere.

how many times a day do you feed? and what food do you use? what was the ph before you added chemicals? your bioload might be too much since its a new set up. try getting some used filter media from a LFS and throw it in your filter. also what filter are you using?
