Plastic cushion for bottom of the aquarium for heavy rocks

[rlking58]

Where do I find the black plastic 1 -2" WEBB like material to put on the bottom of my 55 gallon tank so that I don't place these heavy rocks on the bottom of the glass tank?

You could use egg crate (not the foam for mattresses but the white, plastic grid light diffuser material) or plastic canvas/knitting mesh sold in hobby shops. Both will prevent direct contact of the rocks with then glass. IMO the egg crate will do a better job at diffusing the weight.

I'm not familiar with that, but our local Home Depot or Lowe's should have egg crate, which many people use.

light diffuser (eggcrate) is a regularly used product to remove hard or sharp objects from the bottom of aquaria.

I use the plastic/rubber mat that you see in kitchens on the drainer by the sink.
I put about 250kg of slate on top of these with no issue.

I used a piece of polycarbonate about 1/2 thick.
