Introducing Myself

I would have never thought of that, thanks. :shock:

Yeah, eleyen, that's a good one. Another thing is I would not drill any holes, even for a closed loop, low in the tank. If your pump or line springs a leak, the entire tank will drain. My closed loop drain is only a couple of inches below the water surface. Also, I don't see any need to drill returns for the closed loop, just hang PVC return nozzles over the tank. I'd be interested in the calfo style return manifold; if it's anything like his overflow set up, it's a big improvement on the "standard" design. Why don't you try making one of those manifolds? You don't need a complete circuit around the tank rim; as long as the manifold is capped at the ends, you'll get pretty equal pressure out all of the nozzles.

Hey Matt. I think I'm gonna try the manifold out on my 38. Wanna help me experiment with it? Might take awhile to get all my parts (pump, sump, nozzles, etc) but i should be able to set it all up in a couple months.
