Moving water up hill

[Chrisgarrick]

Ok Im redesigning my sump cause of the glass 70 wont fit in to the new space. I ordered a ruff neck (I think that's the name) but its a 70 gallon watering trough. I also ordered a 20 gallon that will sit above it and be the first vessel that my drain will run into. This will also be the container I put my skimmer into. The water will then exit the 20 gallon via a wide cut and flow into the 70 below it.

I saw pictures of this set up and want to use it because it will fit square into the space in the new closet with out jutting out into the doorway.

Now for the question. I would like to put the 20 as high up as I can actually Id like to have It completely out of the 70 so as to not displace any of the needed 70 gal volume. The top of the 300 gal DT is right around 6 feet and the bottom at 3 feet. I'm going to have my drains exit the 300 and make as fast a 90 degree as I can so as to get as much height available to put the 20 above the 70. Question is can I place the 20 up above the 70 even if it is above the 3 foot point of the bottom of the display tank?

Think about when you syphon water - it will keep flowing until you get it above the water line of the tank your cleaning. Wont this work for me? Push water uphill
If you can see flaws in this tell me please.

Simple answer, YES!


You just can’t have the exit of the drain pipe (or the maximum water level in the 20) higher than the water level in the DT.

And I'm assuming a "conventional" overflow with the drain hole at the bottom.

Yes. That is what I hoped. It will utilize the square footage of the closet and save my back. .
