Too much for flow for a 90?

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.
