We run a 30 gallon cryptic refugium plumbed into our 2x60g displays and sump w/chaeto. We have approx. 50#s of rock in it and we have 2 - 14 inch brittle stars in there along with a ton of pods and sponges. We placed the cryptic higher than the display tanks and we use an old Fluval canister filter to supply water to it. The Fluval (without filter medium) draws water out of the display and pumps it up to the cryptic. We drilled the cryptic near the top and added a bulkhead and plumbing so it overflows back into the DT. With the overflow method the pods dont go through an impeller before coming into the DT. We run a small powerhead in the cryptic and once a week or so I use it to blow off the rocks and bottom and all the crap goes out the overflow and into the DT to feed the corals.
