Adding More Flow, Help or Hurt ?

[MaineReef88]

I have a 90g display that has been up for several years now, I have just recently upgraded my lighting and purchased a skimmer and I am going to start adding corals, clams, and that sort of thing. My question is about the amount of flow in the tank, The tank has been running with 2 Hydor Koralia Evolution pumps that each pump 1400 gph, and the filter adds an additional 198 gph of flow, I have an extra Koralia 3 ( cant remember how many gph this is) and I was thinking of adding this, at a different angle than the other two, So Would that just be a plus to the reef, or is it too much flow for a 90g? I cant seem to remember how much is too much!
Thanks!:spin1:

40-60x turnover is a good number to shoot for if your keeping sps.

Thanks! I certainly wont be starting out with SPS, as I am going to go into the corals slowly.

You should be fine as is but will need to add more as the tank grows in or you add more flow loving corals.
