I originally was planning an L1, but it became cost prohibitive. Plus there didn't seem to be much demand for it. The UAS seems to be a better fit for nanos. But I think you have a better view on that, having both.
Oh okay thought I would check. Looks like I will have to figure out another way to filter my daughters tank. I had a Hog.5 on it for about 5 months and it did nothing for it. I did all of the recommended mods to it to the point of it looking like Swiss cheese... It just got filed to the blunder pile.
Well, how much room do you have above the tank? Is there a lid on it? Light fixture? I'm going to move this conversation to the experimental scrubbers category...just fyi
