Hi, I just started a 50gal tank and used bio spira,I added a few fish 2damsels and a shrimp with a feather duster.I added the bio spira yesturday (Sat) and the next morning I looked at my tank it had killed every fish (Not The Feather Duster) it was also foggy,Was it susposed to kill the fish I added? I thought the cycle was susposed to go so fast it wouldn't kill any fish. I'll check the nitrite levels to see if it had gone down.
