Sump question

Pope258 · Nov 13, 2020

Hi, I’m setting up a marine tank for the first time after years of keeping freshwater, ive bought a tank and all the equipment, only thing im questioning is the sump. Im confident in how they work but mine has a divider with no way for the water to pass through, I’ll attach images. If anyone could let me know what this is for it would be a great help, thanks

Welcome! I'm also a proponent of making that an ATO chamber. Let us all know how you end up configuring the sump.
