Return pump / sump questions ?

[Enigma]

I use two of the Eheim Compact 2000 pumps in my main system, and they are great. They're quiet and low wattage.

I'm guessing that your sump isn't baffled?

I've just picked up one of these skimmers as well, so I can't comment on it yet. I have read that there can be issues with microbubbles, so I would try to position it in a way where the return pump won't pick up too many of the microbubbles. That may be tough, and it might require some fiddling.

I have run mine in a vinegar/water solution to get it all cleaned out. There weren't any microbubbles, but a run in saltwater may change that.

I plan on putting some baffles in the sump.
1st about 2 inches below the rim of the tank the skimmer will go in here next I will have 3 baffles that are 4 inches high these will be 1 inch apart and then the final chamber will be about 1/2 of the tank I will have the return pump.
I just got back from J&L and picked up the Eheim Compact Pump 1000.

Excellent. The skimmer should go in the opposite compartment from the return pump: where the water from the display flows into the sump.
