With my current setup (using only the API Rena canister filter), the ph only went from 6.3 to 6.6 in 3 to 4 hours. I don't think all HOBs can degas a lot. With the Emperor 400, there are too much water splashing going on (the spraybars and the moving wheels). Is it as bad as wet/dry filtration and with a sump??? I don't know.

Ive decided not to use the emperor, thanks tetra73!
