Hey guys I'm building a fluidized bed out of a 100 gallon acrylic tank. I measured and had the two pieces of acrylic cut for the chamber dividers. The problem is If I push the piece all the way to the acrylic there seems to be almost a 1/4" gap where water could pass. Is there a way to install this still. I know Weldon 4 would work for the side that is touching the acrylic but for the side with slight gap is there anything I can do?
