Enough Flow?

[JP SPS]

I'm wondering if I have enough flow or not currently.

Tank specs are:
125 gallon tank
1 Ecotech MP40
1 Echotech MP10
1800 GPH return pump split 4 ways with 4 PCI Flow Accelerators.

I figure that is about 54x turnover. Sound about right? I'm just trying to dial everything in before I start adding corals.

I have a 135 with 4 x 1300gph powerheads. And 800gph return. I am looking to add more flow but sps grow good in my tank with that

im running one tunze 6055 and tunze 6100 and a mag9 return in my 50g tank. It might be a little over kill but I also dont have a sandbed
