I'm in the very early stages of preparing for an octo tank (just recently introduced creatures into my tank after cycling and all). I've read that the flow rate in a reef tank should be at last 10x the water volume. I've purchased a Reef Octopus space saver 150, rated for 150 gallons and will fit in the small footprint of my sump. It was this or a non space saver 110. The 110 had a higher flow rate in GPH, but was not rated as high. The space saver 150 is rated at 130gph, so from I understand I shouldn't be exceeding that too much. I figure I can do at least 260, because the return to my pump is divided. My question is should I get a powerhead to make the flow 10x my tank volume for the octo, or does it require/can it be ok with less? Am I limited by the sump I chose if the octo needs a much higer flow rate?
