One thing I forgot to add was on the bottom of those three pvc pipes will be elbows to help with this problem. Also, the pipes will not be quite that long. If anyone who has worked with sketch-up, it takes a long time to make little adjustments.

also, just to make sure, you are using an auto topoff of some kind right? if not, that little return section (where all evaporation will show up) will fluctuate quite a bit and you will have to add water constantly.
Someone on RC suggested the same thing and didn't know if this would create too much water for the top tank to handle. I guess I could add a ball valve to control the amount of flow. And yes, we have already bought a ATO for the sump.

Thanks... That is why I like our stand at 46" tall.

The baffles are already on the tank. Someone of RC suggested I remove the 1st and 3rd baffle. I still have to figure out how to do that.

And yes, that is a 6" sand bed.
