SPS / Reef & MP40wes

[Pinchy]

Hello all,

Another newbish question for you. I have just recently purchased an Mp40wes from Dave@concept for my 72 gallon bowfront. What percentage of flow should i be running the vortech on for sps / mixed reef? I have a couple of SPS frags in the tank (plan to have plenty more), a fluval 304 canister and a sump w/ehiem return pump (running on lower setting). I currently have it running on a lower setting probably around 40-50% (Reefcrest mode) and there is already a TON of wide flow in the tank. My bangai cardinal looks like he is getting blown away no matter where he goes. (Perhaps i should think about selling him). Your input is greatly appreciated!
