I didn't talk about it because I don't like there design. They are hot boxes just waiting to crash. The filtration system is poorly designed and hard to maintain. That's why I linked you to the media basket. Fits right in the RSM and pulls out easy for cleaning.
As with all nano's, you need to skip the idea of a skimmer and focus on carbon/media filtration and husbandry for long term success. Lot's of water changes and temperature control.
I'm not a big fan of the bent front corners either. Hard to maintain, scratch easy and distorts the view.
