Critique Simple Sump Design Please!

[DeltaUguy]

Here is the simple sump design I plan on using. The tank is a "RR" Oceanic 75 gallon with single corner overflow. Sump is going to be a 20 long glass aquarium. All I need it to do is hold my heater, skimmer, and return pump. As of right now I plan on using a Dolphin DP1200 pump. I plan on using ridgid PVC for the drain pipe and flex PVC for the return pipe with a ball valve to throttle back the pump.

Is it adequate for the task at hand? Are there ways to improve it?
Will the piping work in the configuration it is now?

Thanks for everyone's input.:)

If it's at all like the picture in my head, then it will work just fine. Why not use the flex pipe with a valve for the drain? That way, you could easily remove the sump for maintenance and cleaning without losing any water. I know that all of our future plumbing will involve lots of gator clamps and valves, so that any peice in the system can be turned off and removed easily.

Oh sure, now there's a picture! ;)

What about baffles to keep bubbles out of the main tank? How do I make them, place them?

I'm baffled (pun intended)!!:D

Couple of methods...One is to reduce the distance the water drops by creating a tilted platform below the output hose, so the water will hit the platform and then 'slide' into the main body. Another method is to put a curve at the bottom of the pipe so the opening is just below the normal water level. You'll get a bit of bubbling gurgles, but not many bubbles.

Or, get egg crate, cut it to fit so you can have a few rows of them at an angle between the incoming water and the pump. They'll get covered in critters though--sponges and what not--and you'll have to clean them every now and then to prevent reduced flow.

Or, I'm not thinking the same thing as you are, or you've added a picture for why you are thinking... ;)

I had planned on having the end of the pipe extend straight down almost to the bottom of the sump, submerged. The water would disperse by hitting the bottom of the sump tank. Will the flow not happen correctly if I do that?
