I have a new aio tank I set up (reef casa 12g). I cycled it, tested the water, and everything came back good (no ammonia, no nitrites, ph good, etc.). I’m starting to get a little bit of an algae bloom too. I introduced my first fish, a clown fish, and it seems to be gasping for air. I made sure there is plenty of water stirring but I can’t seem to fix the issue, any help? I’m trying to keep this guy alive.
