3rd time is a charm...I will try to post this again. I have a 55 gallon tank that had 4 fish in it. Like a dummy I decide it is dirty and I clean it from top to bottom, including rinsing all of the stones and replacing ALL of the water. Off to the fish store I go..with high hopes of a beautiful tank. The lady at the fish store never said a word about conditioning the water..ph, nitrates, nitrites, ammonias. I come home with about 20 new fish. Well, guess what? They are dying one by one. How can I save them? I thought after reading some of this that I had too much ammonia for them so I have already done a 1/3 water change. I dont believe we have chlorine in our water because we have well water but we do have a softener. It has been 2 weeks since the complete clean job and about 3 days since the water change. Now what? Any Help please...and I will name a fish after you!
