I just have an AI Prime HD at the moment. I have a spare Radion xr15 G4 Pro laying around that is overkill, but why not? I just have to find a way to mount it because the RMS mount it too tall t fit in the sump area.
Algae doesn’t seem to be a problem. I have turbos, trochus and ceriths in the sump that do a pretty good job of keeping it clean.
