Plumbing - closed Loops
Done with being an electrician...I became a plumber! I now consider myself to be quite accomplished at PVC plumbing. Many thanks to the guys at Corix Water Products. I became quite a regular there!
Here's a shot of the two closed loops. (Left and Right) Each consists of a Dart pump connected to an OM-4 way. The outlets from the 4-way deliver water back to the tank in such a way that the water will be "rolled" from the bottom/back across the bottom...up the front glass, then across the top toward the overflows. I'm very happy with the OM-4 ways. They are completely silent, very well built and Paul is very helpful on the phone. Even though the two loops are almost identical, I experienced some water hammer in the right loop. A quick mod provided by Paul cleared it up easily.

Plumbing - Return system
I've put considerable effort into designing the overflow system to be quiet.
Suffice to say that water falls through two back overflows. Each overflow has 2 x 1.5" outlets. In each overflow box, one of the outlets is choked back by a gate valve. This turns that outlet into a silent siphon. The other outlet has a durso standpipe, but this outlet is only collecting water that just couldn't go down the primary silent siphon outlet. Emergency situation water testing confirms that even if one outlet is completely blocked, the other outlet(s) can handle the entire flow. That's a G6 skimmer sitting in it's approximate final position.

Details, details
With the tank in place, I've started working on the overhead walls and doors. This was a lot more complex than I thought at first. I wanted to maintain the clean look of an "in-wall" system, but also wanted front access.
I've decided to build the walls and doors out of plywood. At this point, the doors/walls have been tested, but are not yet installed as I need to finish them up before I hang them. I also need to devise some sort of prop to hold the doors up so that they don't crash down on my head.

Water testing
There's tap water in tank. I've been testing the function of my closed loops and chasing leaks. So far, so good. It seems that I will have to make some modification to my gate valves on the overflows....but that's minor.

Very nice journal
Very very well done. I am truly impressed by your foresight and your layout and planning. Love your journal as well with the room layout, then the containers in, then the walls, electrial etc etc.
You mentioned you need some modification to your gate valves on your overflow. Can you elaborate? Where did you get the 90 degree metal brackets for your front and side ramps? I see an air duct in ceiling - does this goes into your house's furnace air return? If so, any consideration to venting the air directly out of the house? In my setup, I am looking to install a dehumistat on my fan to vent moist air directly out of the house when the relative humidity gets too high. great job.
