OK I have drawn up a plan for a custom built sump. Here is what I am thinking:

Any one have any input as I am really just making this up as I go. Basically green is in from the cpr overflow 1 1/2 inch bulkead in overflow, so I thing it would be same for the piping?

Yellow is from the reeflo, whish is also 1 1/2 inch piping. I will be using some sort of a Valve to scale back the flow if required from the reeflo.

That last chamber is where you will notice the water level drop due to all the evap from your tank. The smaller the chamber the quicker your pump will start sucking air and frothing your tank up with bubbles. Unlesss you have an Auto-Top-Off unit you will be having major bubble issues in no time.

Another thing to keep in mind is you need to make sure you allow for power outages and the amount of water in your pipes and overflow backfilling into your sump. Your do not want the sump to overflow and you do not want any water getting into the dry area. Make sure those baffles are low enough and the rest is high enough where there is a slim to nil chance the water will not get to places its not supposed to be.

What size is the chamber for the "Fuge" spec'd at?

the fuge is is about 6x17 inches. should I just give up on the refugium idea and use this space for the holding area for the return water?

Or you could remove the sperator and fully submerg your return pump.

Or you could use Zeovit and win big.

Not if he wants to go with a Sequence Snapper. :razz:

You may want to think about a submersable pump though. One major reason would be if you plumb in the Snapper like you have in the drawing you won't be able to take the pump offline to clean it without a lot of effort. Your design and space available would be a much better fit for a submersable pump IMO.

So that would be a smoke and magic thing then. When the smoke gets out the magic is gone. :lol:
Ok, so what is the hight of the sump and the hight of the stand?
Could you build something above the sump and place the return pump on that?

I have room on the back of the stand, what kind of performance loss can be expected due to the pump having to suck the water up 2 feet?

You can clean external pumps easy. Just make sure both the inlet and the outlet are plumbed with true union valves.

Yes while true, Robb's design wouldn't have enough room to install a TU Valve before the pump.
