Wet-dry is the nitrate factory if not maintained properly plus it is not all natural so don't go with it.

Here's a sump I made for a member. The right side is where the overflow from your tank would enter. That's also the chamber for the skimmer. Then the water flows over>under>over through the bubble trap into the fuge section. The last baffle overflows into the return pump chamber.
