Struggling to get SPS growth

[Xandernfs]

2 MP 40s are great for that setup but I wonder if you have them running too low for an SPS dominant tank. Recommend watching the BRS TV episode on flow on You Tube. BRS and World Wide Corals (WWC) say flow is the single most important thing in an SPS dominant tank ( more so than light) and it's better to have way too much than not enough. Random flow is important so you're not blasting the coral the same way all the time.

My pipe organ is flowing like crazy and my frogspawn/octospawn is in the corner since it's quite a bit. The polyps on the SPS are moving pretty well too.
