I just did a 30% and added prime, have 2 casualties =( I quarantined the others in another tank for now... I always add prime, I pour it into the stream of water from the hose when I am refilling the tank... Good thing I have the day off, I would have came home to a dead tank. I tested the tap, other than my water being a little soft, which I have some GH booster I use, perameters are great. My test strips don't show any chlorine or nitrates. The tank water has high nitates of 40 low PH of about 6, and .2 ammonia. I don't know what happened?
Tap water is as follows: alkalinity 80ppm PH 6.8 nitrate 0 nitrite 0 GH 25ppm
