I have 2 sumps and there both different. One is in a tub, 17"x26" by 12" deep. The return pump and skimmer are on one side. I have about 4" of live rock on about 1/2 of it. the various algae grows and clings to the liverock. for lighting i am using a 45 watt 6500k photographers bulb in a cheep hardware store reflector. This is on a 50gal breeder with a 3" substrate over a screened egg crate to make a low oxegen zone. Its simple an works.
The other one is a 55gal under a 90gal tank. I have 12 layers of fiberglass screen (for a low oxegen zone) covering the bottom,with a 1/2" of substrate over that. I have a "critter home" under the return pump. Its a box with 1/4" mesh screen pieces, various size lengths and diameters of plastic tubing and pvc. there are 2, 1/4" mesh dividers about 3" apart filled to the top with ruble to keep the algae away from the pump and spread out the return flow. Lighting is a 150 watt,14k mh. This one has been set up for 1 day.
If you have all the zones it will work.
