2 MP40s enough?

[SifuMemphis]

In a RSR 525XL, will 2 MP40s, one on each side be enough for SPS tank? I am considering also adding in 2 Gyre 330s but figured if the MP40s are enough, I can save some money.

I’ve got 2 MP40’s in my S650 so you will be fine, they provide more than enough flow.

I removed the 4 rear circulation pumps over a year ago and the MP40’s are run at around 90% mainly on reef crest but there are different programs etc

You can also check on the ecotech web site, there’s a flow calculator
