So now the question is where would you have the closed loops. Both intake and return? How many closed loops would you have to keep a good current in a peninsula tank.
Personally I was thinking of having the sump returns at the top of the overflow side. Then have two closed loop retuns about midway down the overflow side. Then have two more closed loop returns closer to the bottom. I was thinking of putting in an om4-8 way. The intake would be near the bottom, coming up through the bottom, near the opposite side of the overflow side. I was also thinking of putting a few more closed loop returns higher near the opposite side, again coming up through the bottom, that would be aimed at where the water overflows.
What do you think? How would you change it? I know going up through the bottom probably isn't good but I want to be able to hide it all and not have something you can see coming down in the water from the top.
Tell me what you would change and why... please.
Sorry I would diagram it but I don't know what to use to make good diagrams.
