Hi. I was researching for a skimmer and realized there’s not enough space in the back chamber of my aio for one… I’m going to keep anthias in this so at some point I’ll be feeding quite frequently. While I’ve been considering doing a macroalgae tank I do have a tomini tang in the set up already. Another thought is a refugium in display hoping the chaeto will absorb the excess nitrate. I do have a butterfly in the tank too I’m worry if there’s no skimmer the water quality will be too bad for the fish, even with a refugium. I do 10-15% water change every week and vacuum the sand bed while I’m at it. Also moving the sand to even it as the flow always blow it around. Will it be okay to not have a skimmer or there’s some other way to do this?
