It looks OK, they inject bubble stream right in to the tower ( no bubles in return), also that "Swirl" in the tower is a longer contact time looks good .
I know you need a large pump , but that what I use anyway because i like more water turnover in sump, skimmer and refugium.
Anyone ?
In my opinion the Aerofoamer outperforms the EuroReef ...
