No worries! Yea I just added one last Friday. I've got the Innovative Marine 20 and got their 9w sterilizer for the left intake. I had a skimmer after that chamber but swapped it for some additional mechanical filtration. Other side has the full media basket with just filter pad and carbon right now and a fuge after. I have GFO for if Phosphates rise too but not running it currently.My bad. I went to your tank thread. Your last post there on Feb 22 said you were using uv sterilizer?
It's really not that bad, it almost looks like it's clearing some. I wonder if something got stirred in the bed before lights on. I do have cerith's that like to burrow
