Sump Pump

[Bob]

I have used and still use overflow box's....the design is so much better now....I have one on a 72 gallon tang...Even if power goes out...they start up just fine....buy a pump that is rated higher than you need...I use a aquamedic 3500

Over flow boxes work however I still don't trust them ... I have drilled the top back of several tanks and find that to work just fine. Get a sump return pump that will handle the head pressure you will have from pumping the water to the top of the tank however don't use too big of a pump as it could over power your filter in your sump .... use your return pump for just moving water to be filtered not for flow in the tank.

Thanks for the information guys. I'll have to do my research and get a grasp on what I need to do. Thanks again for the advise.
