Something strange is going on fish deaths now
Woke up this morning to some very sick fish, one has since died and some others probably won't survive the night. It started with my wcmm and moved on to my guppies. I removed the sick fish to a container I had to use as a hospital tank and filled it with fresh water treated with prime. It did not help. So far my neon tetras do not seem to be affected. I checked my water parameters and they are good.
ph 7.0 or close
Nitrate < 10
I did a water change and the situation did not improve. This all started with a water change I did on Sunday past. The only difference with that change was a switch from Aqua brand water treatment to Prime. Could this switch be causing this problem? I have another tank which has be brought up on prime and is doing just fine. I'm really at a loss as to what happened, so sad, I only just started this hobby back in January, really was enjoying it and now not so much. I just purchased another 20 gallon about 3 weeks ago and it is going through a fishless cycle right now. Honestly I've been reading posts here, and learning as much as I can and tried to do everything the "right way". Really discouraged now and feel like just packing it all in. So disappointed .
