Mitrillion Posted December 14, 2015 Share Posted December 14, 2015 So I have a inative marine pump that came with my 38 gallon nuvo and I was feeding my tank when I noticed my spin streams weren't working so I cleaned them and got them going and the flow coming off them was that of a garden hose barely on pushing out little to no water... Any thoughts on a new pump that could fit in the back of my tank and that is fully submersible? I run mostly sps and would think it would be better for my flow?

Bicyclebill Posted December 14, 2015 Share Posted December 14, 2015 You could disconnect one of the return lines and run full flow through one. That's what I did on my IM20. Putting a bigger pump has the risk of your overflows not being able to keep up. I have to dial back my flow on home tank for this. I'd recommend a powerhead in the tank for actual flow within tank. Return isn't going to supply the kind of flow you need. 1 Quote Link to comment Share on other sites More sharing options...
