So I am about to start...

[Debacle]

...a new build. Actually, I am downsizing my current system of 2x125g, 80g sump, and 60g frag tank. Replacing the 2x125 with 1x150 tall and moving it upstairs to the living room as the current system doesent get the love it deserves in the basement. I have been playing with a free program from Google called Sketchup. Not the most intuitive thing to learn, but it helps to model pretty well. Well, I have completed a few models of the system, but just want to get others opinions.

System will be a 150g tall SPS dominant reef with 3x Radions and 2 retrofit dimmable 39w T5s. Sump and frag system will be in a basement room directly under the tank. Tank itself has already been drilled as a CL system. Plan to run the CL using a Vectra L1 in reef crest mode. Return pump in basement will be a around a Panworld 200PS, maybe a bit smaller. Second pump in basement running frag/reactors/skimmer has yet to be decided. Possibly another L1. Only thing I have changed from the attached pics is I am NOT going to be putting ball valves on the CL returns on the tank. Dont see much of a reason for that now that I look at it.

So, anyone give me thoughts or suggestions. Trying to make this the most easy to mantain system I have had to date. If its hard to keep up, maintenance becomes a chore.

Forgot to mention. Orange is CL. Green is flow for reactors/skimmer/frag tank. Blue is return to DT. Gray is flow to sump.

Looks good...wish i would have done this with my 90 gal i currently have as it is right above a storage room in the basement. Not sure I could convince the wife to cut a hole in the floor though lol. What is plan for stopping back pressure when the return comes off? I don't see a check valve in the return line.

I have went back and forth with the idea of a check valve. Still undecided. In the event of a power loss my sump SHOULD be able to handle the extra amount. Something I am also planning to do is put a lip on the table the sump is on (raised for ease of maintenance and creating a siphon to clean detritus), coat it in a epoxy type paint for waterproof and putting an overflow line directly to the sump. That way if it overflows, it goes directly down the drain. Until that overflows.

I also will be putting several 2" and 1" flow meters on the lines to measure flow and shut off pumps if necessary.
