I run 100% on Reef Crest Short pulse.. With 2x mp40 and 1x mp60 a
and no issues.. in a 125G.. so I would just play with it and see what your tank likes.. there really no right answer to that.. and your bangai cardinal will just have to learn to swim abit better! theres no way your going to make more flow in your tank then the ocean can produce so get that water moving cuz SPS LOVE flow!
