Should I use Plexi-Glass or Glass for the Refugium divider in my sump? I plan on using Plexi for the baffles, but those won't be under as much pressure as the refugium divider.

Also, I bought All-Glass Aquarium Sealer for this job. Will this work OK?

is the water level gonna be higher that the divider for the refugium?if so i would say plexi will probly work,but of coures ,glass will be stronger.i use plexi for baffles in my glass sump.

The water from the refugium will flow over the divider into the sump area.
