Best In-sump Protein Skimmer for a 12g tank with 10g sump
 

I have yet to chamber off the 10g tank that will act as the sump/fuge.

The future-sump's total dimensions are:

16"x10"x12"H

What do you guys suggest for a protein skimmer?

tunze 9002. silent and works well

AquaC Urchin is worth looking at.

I had an Aqua C, it worked great but was VERY noisy. I ended up buying a Tunze DOC 9002. It doesn't skim quite as well (but it does a good job) as the Aqua C, but it makes 1/4 the noise if that. It is also much easier to empty and clean.
