I have one mp40 on my 6 foot 220. Have the opportunity to get either 2 mp40s or 1 mp60. My dilemma is which and if I get the 40s how should I arrange them? I have a big center overflow so I can't use one in the middle back or as a flow source behind the rocks since it would get blocked. So do I put both 40s on 1 side for sort of a surge in anti sync? Or just one giant 60 on the end? Thanks!
