well I already just changed out 90% of the water again, so it is prettymuch a new tank. Cloudyness is almost gone, and remaining fish seem happy again.

well I'm gona get the water tested tommorrow, mabey that will tell me somting. Thanx for the input

ok, but would it happen that fast. I havent ever had any problems with this tank, with these fish, and would adding three more fish and changing the filter cause only the Balas to die in a 24 hour period? Could it be a Bala specific diesease that the new one brought into the tank? and that is 90 gallons, not liters...oops

So I have a 90 GALLON comunity tank w\3 iridecent sharks, 20 or so rasboras, and 10 tetras. yesterday I did a 60% waterchange, removed the old rocks and sand, and scrubed the algae off the tank (no chemicals used) filled the tank back up(used conditioner)added a new large Bala and two small plecos. This evening I notice that all the fish are at the top gulping air, the water is really cloudy and my filter stopped(I have a large cannister filter) So I change the filter and go out for dinner. When I came back all 9 Balas were dead.... what the hell happened???
