I've been really curious about how well "micro" skimmers actually perform in AIOs. Have you had one since early on? Or is that a later addition? I'm also curious about the UV sterilizers for the AIOs.
I'd LOVE to be able to run a CO2 scrubber for the pH boost, but I'd rather avoid a skimmer if I can. One more (moderately expensive) piece of gear in an already cramped space. My nutrients are doing fine, though. I have the stock media caddy on the left with filter floss on the top, and until a couple of days ago GFO and carbon in the other two spots. I added the InTank Refugium caddy in the second chamber a little over a month ago (with the AI Blade Refugium light) and it's going great so I removed the GFO. Just yesterday I replaced the carbon with the "new" Maxspect Nano-tech Clear Cubes. I'm curious how those will perform. It would be really nice to not have to replace carbon every few weeks (the cubes are supposed to last a year in a tank twice the size of mine). The other side of the tank has the InTank filter floss holder (just replaced the sock), some rubble, and the heater.
Anyway, I'm eager to watch your tank progress!
Not OP, but I run the Bubble Magus MiniQ on my IM 15g, it works really well. Fits nicely in the 2nd slot. I had to use some foam to block microbubble from entering the evap chamber, though, just a heads up.
