Vortech recomendation.

I am setting up a 2'x2'x2' 60g cube with a center overflow. I want to keep a mixed reef. Both powerheads need to be on the back wall. In order to create the best flow for this particular tank, which powerheads would you recomend and how many of each? 2x MP10w's? 2x MP40w's? 1x MP10w and 1x MP40w? Does Ecotech still make the MP20's? Thanks in advance!

I'd go with 2x MP40w's each placed on the back wall but clear of the center overflow. I'd then use long pulse mode with the pumps on anti-sync and a period of about two minutes or longer. This will create a fantastic gyre flow around your overflow and will work great. I would go with very low flow through the sump to avoid the return from disrupting the gyre that you can create.
