I have a 12gal nanocube deluxe I use for a
SW application. I have had it for over three years now with no issues. The deluxe version of the nanocube had higher lighting so I ended up opening up the hood and reversing one of the cooling fans so that one draws room air into the hood with the other one blows warm air out of the hood. It has really helped with temp control.
Yes..the nanocubes are made of glass. The scubber will be fine.
