Ok, Im still in the late planning stages, (still in Iraq :P) Let me know what you think, and tell me if something doesnt look right, or wont work. I have a fairly simple plumbing setup planned. Lil black ovals stand for ball valves, and lil black lines stand for unions, sometimes just male and female npt in spots that can easily be removed. Thick lines are 3/4 in plumbing, thin is 1/2 in. Spaflex will be used where ever you see bends in the pvc, but will be hard pvc close to the ends.
We will start from the overflow (purple line inside the main tank). I plan on using both bulkheads as drains. The smaller (1/2 in?) will feed directly into the skimmer (ASM G3 Mesh and Recirc modded), with adjustments made with the ball valve close to the main tank. Notice the drain pipe is much lower than the main drain to ensure it is constantly submerged completely. The (3/4 in?) larger pipe will go into a small section filled with rubble first. From there it will go through a 3 baffle bubble trap, to the refugium, and 1 baffle to the return section. A Mag 9.5 will return water to the tank in the center, plumbed over the top.
Next is the closed loop. I dont know if this is possible with a large pump, but I planned on using the same idea from melevs famous 29g cl. The pump is a genx mak4. 3/4 in plumbing will draw water from inside the overflow box (just to ensure nothing accidentally gets sucked up). Notice the T fitting at the top. It will have a cap on top to prime the pump with. It will leave the pump again at 3/4 in, and hit a Y or T fitting and be split into 2 pipes 1/2 in each. Each pipe will go to the ends of the tank to be again plumbed over the top, with a possible penductor on each end.
Now here are my questions. First, can the over the top closed loop be done with a pump as large as a mak4?
Should I go to 1 in plumbing split into 3/4 in legs?
What size bulkheads are the standard Oceanic overflows?
And other thoughts or suggestions?
