135 build sump questions

[Jonnypro]

I was given a 135g tank from a friend. Now I am building a sump tank for it. But the only problem is that I want the tank at ground level. Like only like a foot off the ground. I am in a basement so I can't plumb down. I can put it on the side but I wouldn't be able to let gravity work. I would need a pump. Here are some pics. Also I have a 55g fresh that is above it. I do not want to move it because it would look dumb with a big one on top and small one on the bottom. Now the 135 has to be polished out. Let me know. Any advice would help.

Why couldn't you just let it siphon from one tank to the sump. ( just like a hob overflow. ) when a good siphon is made, when the dt water level gets higher than the sump it will just try to equal itself out .
