Pump and flow for 90RR help!!

[Ariel110G]

So this past Sunday I have upgraded from my 75G tank to a 90RR tank (1 inch drain and ¾ return) with a new tall stand with a combined height of tank and stand 6ft tall, the pump I have used on my 75G is the marineland 5500 with 1,385 GPH, I had plenty of flow coming out with the old setup but now with the new tank and stand height I'm for sure getting less than 700 GPH coming out, I have a MP40 and MP10 the sump I have a the MegaFlow #4, my tank has a mix of corals, but mostly softies and some SPS and anemones.
When it comes to flow I like to be on the high side 10X or more, I think my total water volume is more than 100G sump and tank, so my question is do I need a new pump? Or having the MP40 & the MP10 with the pump that have now is good, I was thinking of getting the Fluval Sea SP4 with 1822 GPH after the height I'll probably get about 1200 GPH coming out will my over flow can handle that???

Well right now your a little over 7x turnover through the sump per hour which is really good. If you want higher flow through sump go for it but your already on the high end of whats needed. Most recommend 5x.

The mp40 and mp10 on a 90 is plenty of flow.

So, what I'm actuality thinking of doing now is getting the Fluval Sea SP4 with 1822 GPH and making a manifold, to feed my 2 reactors that I have, with an option for another one, because right now I have a total of 4 pumps in my sump!!!! One for the skimmer one for every reactor (I have 2 now) and one pump for the return. So do you guys think that the Fluval Sea SP4 with be good for the 2 reactors and return to the DT?

I have a nextreef mr1 carbon and the nextreef msr1 bio pellets

I will like to get some more opinions before I pull the trigger on a new pump, I'm looking to get the
Fluval Sea SP4 with 1822 GPH the total height of my stand + tank is 6ft tall, I'll have a manifold so ill connect my two reactors to it as well, and maybe a 3rd one or a UV.

Thanks for the help
