I have a Red Sea 170, i bought the octo Essence 130 protein skimmer for my sump. The water height at the baffle in the sump is just under 7.5 inches. I added a baffle with holes to split the sump and have a refugium on one side. Is 7.5 inches a good water height for this specific skimmer? Or should I add a piece of glass to raise the baffle? The baffle I added is lower than 7.5 inches of the stock baffle in the sump so the water would flow over that one. Here are some pics of what I am trying to do. Thanks
