I recently made a post about my terrible experience with Dr Tims Waste Away. Im not here to talk about that anymore. I need help and recommendations. I only have three fish left from the 8 I had. I want to make sure the remaining 3 survive. I dont see anything wrong in the tank. I know the oxygen is depleted which is why the fish died. the clowns now are not eating. When will this stop? when will the oxygen stop depleting? I last dosed on Thursday and the fish have been passing away one by one each day. Im extremely worried for my remaining tank mates. I dont know what to do. I feel helpless. I have two wave makers on on full blast. I have an air pump pumping air in with the lid open. What else can I do here. I only have two clown fish and a goby left. The goby is eating and seems to be doing fine. Im very worried about the clowns though. Should I do a water change tomorrow even though I did a 50% water change on thursday?
