I put some Ultra Life Red Slime Remover in my 20 gal. to take out the Red slime and so far after a week some of the slime(hair algae) has receded but I have lost 3 fish. I checked water Every day and all tests are good. I lost a Garamma,spotted Cardinal,and this morning found the Ocellaris dead,and haven't see the Fire Fish Goby yet. The Ocellaris and Goby were active and eating as usual yesterday,----but today? The snails and crabs seem to be ok so far.I made some water changes about 4 days after using the Ultra Life (20%) each time. Has any one had this kind of result with this treatment.If the treatment is the problem,Should I start over with this tank (clean it out and start over) or would 50% water change do to weaken the Ulta Life effects. I also checked water today and no problems showed there.
