I have a Waterbox marine tank with the filter socks right now and want to switch over to a roller mat setup. While looking at roller mats, one thing in common for all of them is they need the drain to be plumbed directly to roller mat. This seems its simple enough to do, its just a few elbows and a section of flexible hose. But Im wondering, on the current Waterbox marine sump, the main and emergency drain water first enters into a thin compartment in the sump and overflows into the filtersock compartment. If I replace the filter sock with the roller mat, and have the drain plumbed straight into the roller, then it basically leaves that first compartment where water drains into first useless, or water will be come stagnant or have VERY little flow when the occasional water enters the emergency drain.
Im wondering if I could 3D print a funnel or something that catches the overflowing water from the first compartment, and direct it into the inlet of the roller mat. should look something like this
I think it should work, but not sure if there would be any gurgling noise from the funnel, or if there would be any flow issue entering the filter.
Modifying the sump is an option, but not something Im willing/want to do since its not as simple as just removing a piece of glass or 2.
