the height of my sump baffle is just short of 7.5 inches, I have bought the reef octopus eSsence S-130 protein skimmer. online it recommends being in 7-8 inches of water. do I need to raise the baffle height or will it work fine in under 7.5 inches of water?? I am using it in a Red Sea 170 tank. I heard most skimmers don't need to be that deep, but if anyone has this exact skimmer please let me know what depth your water is at. thanks!
