Do I need an over flow pump?

[Jordan berry]

I thought I had everything I needed for my tank. Someone just mentioned how to match the return pump to the over flow pump. I have a dc9000 return pump for my 90 gallon long setup with a 35 gallon sump. Do I need an over flow pump or is it gravity fed through the holes? Also if I do need an over flow pump what pump should I go with?

Perhaps I am not fully understanding your question, but you do not need a pump for your overflow. The return pump will pump enough water in your tank so that water will flow over and through your plumbing to your sump. Gravity is all that is needed.

Awesome all I needed. Thank you. I like asking questions on here rather than calling and bugging the lfs in town. Thanks again, Jordan

Once you have the proper sized overflow box and plumbing going to your sump you are good, no need for an overflow pump. Gravity will do the rest. If you like you can always check out the Bean Animal overflow setup. That works pretty good for me. Just my .02
