I have two tanks. One that's a 5 gallon and one that's a 22 gallon. Yesterday I did water changed on both using the same water from one big batch. Anyways, about 4 hours after the water change the fish in the 5 gallon were struggleing. They could hardly breath and 2 fish died. The third (a clownfish) who was breathing very heavy I was able to rescue and put in the 22 gallon. I checked the salinity, PH, nitrates, and nitrites and all seemed fine but obviously something is wrong. Anyways, the clownfish is safe but I still have no idea what caused this. Anyone have any ideas?
