Too much for flow for a 90?

[geforce]

Hey all, I recently got a awesome deal on two mp40's giving me a total of 4 now for my 90 gallon. My question is should I sell the 4th one because 4 mp40's is overkill for a 90? or should I add the 4th one to the current setup.

I currently have it so theres 1 mp40 on each side of the tank and the third mp40 center backglass and dialed down to 50%.

Currently I dont notice anymore dead spots but debating if I should sell or not.

Input guys?

If you are going SPS absolutely keep the forth.
I personally would keep the forth and just dial it down a little, especially if I did not have much sps. If you have an Apex controller I would definitely get the WXM, the control is phenomenal.

I have apex and the module I have a few sps but some softies also, yeah think im going to keep it then just didnt know if that was too much lol

i have a 120 not a 90<6 inches wider> but 2 mp40s and 2 similar sized jeboo units. EVERYTHING IN MY TANK LOVES the flow. lower flow corals you just have to find a sweet spot for them where the flow is broken.
