Adding new pumps which one?

[SifuMemphis]

I Currently have a Red Sea Reefer 525XL, which will be SPS dominate with some zoas towards the bottom. I currently have the following:

1 MP10 (behind the tank, on constant blowing detrius away from the back)
2x MP40 , one on each side.

I am considering adding a Maxspect XF350 on one side as well...Do you think this one is too strong? Should i get the 330 instead?

Also, should I get just 1? Or should I add 2, one on each side?

Ecotech are less maintenance, more constant/ reliable flow

It sounds like you’ve got plenty of flow already with what you have to be honest

Ive now got just an MP40 at each end of my S650 system and thats more than enough for that system.
