Flow Help!

[Andrew]

The tanks a 37 gallon tank. 20'' long by 18'' wide by 24'' tall I believe. I plan on putting two 6025s on the bottom of the tank behind the rocks to point twards the starboard. Should I put two more 6025s or two 6045s at the top of the tank than? So.... 4 6025s or two 6025s and two 6045s?

Really, I think two 6045's should do it, one blowing along the bottom on one side, one blowing across the top on the other.

Even for SPS corals? I dunno if I should invest in the 6055s or not. In that case, I would get two 6055s and not worry about the smaller pumps.

The 6055's would really be the ideal but I don't think more than 3 6045's would be required.

Might have to get the 6055s and hold off on the DIY skimmers.
