Have started the build somewhat. At least got a good idea on how I want it. Decided to go with 3 separate return pumps from the sump after talking with Shane, though he did bring up a possible heat problem with
running 3 pumps. Have to look at what pumps are available, size and wattage used (lower wattage=less heat). Plus plan on adjusting pump size to each individual tank, figuring a gph turnover rate at 6-8 times quantity. Like the idea of Hydro's and others on using SPA flex tubing instead of rigid PVC. Still have to investigate more concerning the siphon break holes.
Stand will be along the wall enclosed L shaped shelf type and about 20/22" wide on the long section and 26/28" on the short leg. It will be braced/crossbraced 2x6s and 1/2 plywood skinned (top of course 3/4"). All to be painted dark blue. Height still to be determined although I'm leaning toward 38", as I would like to comprimise between viewing sitting down and being able to work in tank. Lights will be hanging retrofit T-5 fixtures hidden by removable false-front canopies sized for each tank.
Again ideas and feedback welcome.

Note: had an idea- raising the sump and drilling a 1" hole in the side about 3" below the top and running a fitting to another holding tank or container directly along side. Would give me a safety margin in case of overflow from power failure. Again would depend on skimmer height. but it could also act as drain for skimmed material. Any feedback?
