Well, I re-thought things and decided that having my return plumbing go right through the back wall posed a risk of overflowing my sump. Even with a syphon break, the water pressure in the tank would still drain a fair amount of water.

Because my return plumbing is now going up and over the back wall, there wasn't really a benefit to closing it all in the way that I had originally planned.

Here are some sketches I did:

I plan on having black acrylic on the back wall to prevent the overflow and plumbing from being visible.

Well, I have been playing around more and learning more features of the program and came up with this:

All of those pictures are to-scale of the actual measurements.

These sketches are still using MSPaint??? Or have you started using something else?

Looks like Google SketchUp to me.

Midknight's right. I just downloaded sketchup yesterday after Albert told me about it.
It... is... awesome! (and free)
I know that Google is taking over the internet (and maybe even the Earth), but I don't even mind.

Looking great Chad! Comming along very nicely and quickly! I cant remember if you mentioned whether or not you gave that pump a finishing pass with something lighter?


That looks like an awesome program! I tried to find it on google but was unable to? Any idea where I should be looking? Im probably just being dense:redface:

Thank-you!

I actually had the brilliant idea of searching it on google right after I posted that, and found it.

The tank looks cool so far. Here are my thoughts:

1. Is the tube in the middle a supply line from the sump? If so, is it going to have something to prevent it from draining water back into the sump if the pump shuts off?

2. Do you think there will be enough flow throughout the tank with all the supply lines running so close to the overflow? You could maybe add 45* PVC elbows to the ends of the pipes on the sides to help circulate the water.

That's about all I can think of.

If this tank turns out half as cool as your little cubes did, you'll be laughing. :wink:

The bulkhead on the inner wall of the tank is the intake for the closed loop. The sump is supplied via the overflow. Even though I couldn't really draw it on sketchup, the plan is to have 45 degree elbows on the returns so that the flow is directed towards the lower front of the tank. With 700+ gph from each return, the circulation in the tank should be sufficient - for my plans at least.
