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:
