My set up (in progress) is a 120DT & 40B sump. I'd like to mount the heaters horizontal after the first baffle of a Under-Over-Under bubble trap leading to the return chamber. What I'm pondering is utilizing either 3/16ths or 5/16th acrylic and cutting two lengths ~2"x 12" (baffles are spaced 2"), drill out holes in them that match the diameter of the heaters to effectively suspend the heaters in the water column. I know in air the heaters would melt the acrylic but my question is: with ~1100gph through the sump, would there be enough flow across the acrylic to prevent it from melting? Could this be accomplished by isolating the heaters from the acrylic with a rubber grommet?
I've attached the image I came across on another forum that gave me this idea; however, I would prefer a cleaner look. I've also attached a sketch of what I'm trying to explain.
I'm tempted to try this in an unused 55g I have sitting around. But want to seek thoughts/experience from others prior.
Mahalo!
