I am in the middle of setting up a frag tank with a 40 gallon sump. The frag tank itself is 24x24x14 so not too big but I want to leave some wiggle room for an upgrade. Which skimmer do you guys recommend? Reef octopus? Swc? Let me know what you think and if anyone has one available that they would like to sell let me know as well. Thanks for all the tips.
