flow for closed loop

[randy123]

I've heard that the newer OM's have small grooves built into the drums that allow a little bit of water by...they say this helps with the sticking that can result when sand or whatever gets in there. The plan for my setup puts the OM in a fairy accessible place as well, so I'm not too worried about that aspect of it too much. The OM is already ordered a few days ago...I got drum #3 for now.

I'll have to look at your thread later tonight Grizz, sounds interesting. I'm at work on nightshift, so I should have plenty of time to go through it...

While I have the tank down and drained for the install, it might not be a bad idea at all to add the plumbing for a second pump, but I don't think I will buy one for now. My wife has been understanding up to this point, but I don't want to push my luck.
