Anyone use this padding under live rock?

[Mariette]

dont want to put live rock directly on glass and putting it on substrate makes it prone to landslides when my fish/inverts go digging. Anyone use any kind of padding under their sandbed?

I've always used "Eggcrate" which is actually lighting diffuser between the glass & live rock. It helps to lock the rock in place, as well as keeping it up off the glass. Comes in approx. 2ft x 4ft pieces & is easily cut with a pair of pliers. Available at home improvement stores. HTH

I’ve used acrylic or starboard in the past without issue to mitigate point loading on the glass bottom. I don’t personally like using eggcrate as it tends to trap detritus. You also don’t want something that is too buoyant like pvc foam board (ask me how I know lol).

You can pick up sill gasket at any hardware store. It's just a 1/8" thick, 3 1/2" wide rolled foam. Cut it to any size. You only need a small pad at contact points.
