Thanks for showing the diagram. It's much clearer now. Below is what I can see from this setup: Pros: - Pump running out of water contributing to less heat transfer. - Lower power consumption due to skimmer pump performing 2 functions. (i.e. skimmer + return) Cons: - The higher placement of the skimmer will definitely requires a stronger pump. (This may cancel off the power consumption benefit above) - You'll need to prime the pump every time to get it started.(Your pump will be damaged from running dry after a power outage) - Difficult to secure pump at edge of tank.(Pump contacting glass may be noisy) - Pump & skimmer requires regular cleaning since detritus flows thru' them before mechanical filtration in the sump. - Flow rate in sump is low as pump is sucking in more air than water.

I used to use aquapharm 2 parts. It was so effective that I had coraline algae encusting my wavemakers...to the point of being a nuisance. Never tried Purple Up though.
