Well, I guess now that I'm starting to get into sps sticks, I should consider buying an mp pump for my tank. I just wanted to make sure it was worth spending the money for the upgrade. Money is kind of tight, so I'd have to sell one of my main corals just to get it. Is the performance that much of a difference to justify the money? An mp10 should be enough for a 36 gallon but down the line I'd like to upgrade to a 65 gallon tank. What size should I go with in case I upgrade. I don't want to have to go out and buy another after an upgrade. Please lmk and thanks in advance, Frank.
