Hey community, happy new year. I'm setting up a Eshopps P-300 overflow box, into a Fiji Advanced Cube 20 sump. My question to you more wise reefers, is how am I connecting the vinyl tubing (have both 3/4 and 1 inch) into the bulk head of the fitting? I just want to make sure there isn't a plumbing piece that I'm missing. Should the vinyl tubing just fit nicely into the bulkhead?
