Sure, it seems really slick. A skimz UP 21

Really great for cubes as it can be hard to find sumps to fit well. Has ATO chamber as well. The socks are in the back which is needed to fit everything in. I plan on reaching from the rear of the stand to make it easier or just going sockless at some point. I am very impressed with it so far.
I know this has been awhile ago now, but can you provide opinion on the Skimz UP21 sump? I am starting a 60g tank and this is what I plan to get so any information would be awesome! Thanks-
