On the contrary...it's a VERY GOOD diagram. I believe the tower and siphon would have to be the same height as the water line in the aquarium as not to overflow if the power to the pump ever stops. I'm not very good at building things, but the diagram seems to be sorta easy. I just need to get the right tools. Are these units commerically produced?
Thanks for your assistance.

What kind of diameter does the tube need to be??? I think I can add one of these to my 120.

4 to 6 inches in diamter...what ever you have room for. you could also Pair a couple of these units to increase capacity. and no I don't know of any comercially produced units.

I just noticed the discrepancy in water levels, what can I say...it was a quick drawing...LOL...In reality the bio-tower would need to be lower than the tank level unless you used a powerhead to feed it. Otherwise the syphon wouldnt work.

I HAVE built these for large ponds and have always wondered about using them in large aquariums as well.

or you could do 2 small sumps instead of one big one or bio tower, you could probably fit to 20g sumps in the stand. to counter act the overflow problem you could place them inside a plastic bin to add some more overflow space.

If you just want the sump to increase the bio load then what about a top filter that sits on top of the tank the water gets pumped out of the tank over the sponges and bio-media then back into the other end of the tank you can make one to fit under the hood and wont over flow as long as the pump is the right size.

The main problem with top filters is that your cutting drasticly into your room for lights. especially if you have a canopy that opens on top rather than the front.

As far as the syphon question goes you can always drill a syphon break in the overflow tube. that way the syphon stops at a set level...It's safe but you have to watch your water level.
