Hello,

I need a return pump for 70g tank. The tank is 20" tall and the stand is 36" tall. I am looking for a reliable & quite return pump, but having hard time finding one within the reasonable price. I was going to get a Fluval SP2. Although it is rated for 950gph+, it seems like this pump does not do well with head pressure. At 56", I think I will be only getting 200gph. This does not account for any 45/90 degree elbows so I will be getting less than 200gph. My Question is:

1. Do you think Fluval SP2 is sufficient for my tank? I am running 2 MP40, so flow is not an issue. However I am little concern with DT to Sump turnover rate.

2. Is there any other reliable and quite pump under $200? Preferably under $150? It does not have to be a DC pump. I am only going to use the return pump to return water from the sump to DT.

thanks,

thanks,

why not the SP4? I have one on my mixing station (have an SP6 on tank) and the SP4 has no issues sending water 25+ feet away for water changes and such...

And Amazon is best price I see currently: https://www.amazon.com/dp/B009XSGHXY/ref=asc_df_B009XSGHXY5203320/?tag=hyprod-20&creative=394997&creativeASIN=B009XSGHXY&linkCode=df0&hvadid=167149786275&hvpos=1o1&hvnetw=g&hvrand=13325576519518782746&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9004070&hvtargid=pla-316086445577

I do not see why a SP2 will not work on your tank, also I thought that they like a little head pressure. Also look into a Mag 7 or 9.

I like the Waveline DC pumps from RLSS. Plenty of power and you can turn them down.

May be a little low flow.

How about an eheim or a vectra?
