We have crushed coral substrate but no undergravel filter.The temp is 80. My husband is the one who takes care of the fish tank but he can't even turn on a computer,so I'm trying to get info from him.He is doing 5%water changes per day to try to get the nitrates down. The bulb is ok. The fish don't seem to be getting enough O2 since they are staying at the top where the bubbles are.I think we just lost the flame angel. It seems they are dying off one by one. Help!
