Moveable Baffle?

[ken_wied]

I want to add a couple baffles to my acrylic sump but I want to be able to move them if need be. Any ideas on a material to use that will make them "snug" when inserted, but not break down in the salt water?
THanks!

You could make small "grooves" out of acrylic in various places in the sump that would allow them to be moved around but still fit snugly in place.

Cut tubing in half and use as borders around and under your baffle.
