what's a good one for a 10 gal my whisper sucks....
Good point. I always keep my water levels way up, but if you aren't able to it could be more of a snag.aquaverde said:Canister would be nice if you're injecting CO2, though. The HOBs always outgas about half what you put in, without some modification of the return or really strict monitoring of the water level to minimize turbulence.
They don't require much maintenance, either.
