First off, THANK YOU... My goal was to have an ultra-professional and clean looking setup, which is the primary reasons that it's taken me so long to get it setup.
1) It is high flow, but the flow rate has been throttled back via the ball-valves. Also, there is obvious flow restriction on the returns, due to the number of 90* elbows used. Keeping all of these variables in mind, I opted to use larger pumps rather than smaller ones, in order to offset the inevitable.
2) The baffles are spaced 1", but I don't have any microbubbling issues like others have mentioned with narrower baffles.
Also, you can't see it, but the Mag-12 that drives the sump will be regulated by an APC RS-1500 battery backup system, in the event of a power surge or outtage. I'll also be eventually adding a secondary battery to this unit, giving me up to 360 minutes of runtime.
