Fish Are Dieing
Hey all.
my cichlid tank is going a bit downhill, one electric yellow has passed on, and the others arnt looking too crash hot either.. my red jewel seems fine and to brichardis are fine along with all my BN and Corys... water parameters are
PH = 7.6
ammo = 1.0 (before a 50% water change then 25%)
nitrate = 2.5 (i think i half forget)
nitrite = 0 ish..
this was all before a 75% all up water change.. i have taken the worst looking electric yellow and put it in my old tank with perfect water and he seems a bit happier.. so i havce figured that i will tdo 20-30% water changes every day till it goes back to normal.. should i add anything to help out and what.. also saturday i put cichlid salt in there spose to make the water like lake malawi. (PH of 8.0 and a hardness of 300ppm ???) please help i want my fish to live :(

Electric yellows . brichardi, bristlenose. and corys would all be fine with PH7.6 For those fish, you don't need the cichlid salt. Is this the 150 gal ? Did you allow the tank to mature or cycle? It sounds to me like too many fish added too soon to a new tank. You will indeed need to perform frequent water changes to keep ammonia and nitrite levels from becoming lethal . you can also reduce feeding to once a day or every other day SMALL amounts. Did you go with canister filters or hang on the back filters? are they rated for the number of gal you have x two? Don't replace the filter material but do swish it around in aquarium water you take out during water changes and stick it back in. This should only need done if water slows down or stops flowing through the filter.Use a good dechlorinator such as AMQUEL+ or PRIME period. Nothing else. Always add dechlorinator to the water BEFORE it goes in the tank. I recall you asking in another thread about why not add all the fish at once. It is possible that your query is being answered albeit in an unfortunate way. My apologies if this is not a new tank but rather a mature tank. In that case water changes and reduced feeding would still be my first choice in getting the parameters back to non lethal levels.;-)

How long has the tank been setup? What's the water temp? How long have you had these fish? What if anything has been added to the water? If the tank has been setup for a while, are you doing anything differently lately as far as maintenance? Any new equipment or decor? See where I'm headed?

Your pH is fine for the cichlids. Ditch the cichlid salts. You do not need it. What are your KH and GH? Ammonia must go back to zero. Doing daily water changes is a good plan. Ammonia is more toxic when your pH is higher so this is something to watch out for.
