They all died, what is considered a "sudden temperature change" It went from 77 to 81 with the new thermometer. I am assuming it was the high nitrate. Sadly I didn't measure my nitrates before my first PWC
. After about a 50% PWC
the nitrates were around 25-35 based on the colors on the API tester.
I am thinking the higher temperature made the bacteria to produce more nitrate. When I found them this morning they were shimming. Then I lost the first one after about 2 PWC
. then lost the other 2 tonight after a 80-90% pwc
. That also may have done it.
I feel sick. I got these fish from a neighbor who gave them to my boys since they were having lots of fry. I know the Nitrites/Ammonia are 0. The tank was cycled fishless. It appears more Nitrate poisoning.
I think some lack of knowledge caught up with me. 3 mollies in a 15 gallon tank even though still young/smaller around 1.5 for the biggest was too much and a lot of nitrate. Also even though I did weekly 50% PWC
and vacuuming the substrate there was still enough wait keeping the nitrate high.
I don't think there was any disease just bad water quality. This means I will be doing more testing with my 75 gallon tank that I have been putting together. There is some good from the mollies dying. Now I can use all the biomax from the AC
30 and AquaTech 10-20 media to cycle the new Canister for my 75 gallon tank.
