I just checked the ammonia level in my tank today and it's at 1.0 ppm. Thursday we did a ¼ water change, and added some stuff the fish store told us to use (Prime by Seachem????) we used the correct amount they told us to use too???? And yesterday we added stress coat. My fish are totally happy and I feed them once a day 9 little pellets for 9 fish. What the hell am I doing wrong???? Please help this is so frustrating!!!!! My fish are so cute I don’t want them to get sick and die!!!!
