Love my bare bottom but get a build up under the rock. A lot of individual pieces I can lift, but others are structures I can't just pick up. Would rather not lift anything. I have seen people use egg crate to lift, but the individual cubes would still block debris in and eventually fill. They would also block any flow sweeping under them to push debris to settling locations. Curious to see if anyone has ever used Epoxy Puddy like from Aquastik to create legs of sort. Was thinking of creating balls of the epoxy to stick under the rock as an alternative to egg crate.
