I was thinking about building a small sump for my new nano reef and I had a question I know that a sump is just like a storage tank with a feed line and a return line my question is instead of using a overflow box could you use a just a plane peice of hose and start a suction on it like you would your siphon hoses for cleaning if you were only going to use a rio power head for a return pump? if so what rio pump would you need if you were only pumping the water back up like 2'-3' let me know you thoughts and ideas on this and if anyone has tried it before thank you. :dive2:

without an overflow box it is very very difficult to get the flow rate regulated. one of them will be overflowing x.x. i have mine set up that way, but if the power goes out, or something, you have problems. also as the water level changes, the distance the pump is able to pump water changes, causing overflows... so if you are vigilant about keeping the tank full, and if you have big enough pump, and if you keep an eye on it, and don't have a lot of brown outs, then go for it :)
otherwise i would reccomend an overflow box. there are directions for them on the internet - i haven't had much success building my own, i may just break down and buy one :)
