Foam as a substrate layer

Hello folks,

I have some Poret foam which I got to make a HMF. Could I also use a thin layer of that underneath my substrate (UNS controsoil)? The shrimp like to pick at the substrate grains, and tends to uproot my dwarf hairgrass. I figure the foam would provide a layer for the grass's roots to grab onto. So maybe something like 1/4" foam and 3/4" substrate on top.

Could make removing some plants impossible if they grow too much inside the foam. DHG is probably fine, but crypts or something would be a huge no go

Should work if you cut the foam to size so it fits snug against the sides of the tank. Though it's given me an idea. Has anyone used poret foam as a form of undergravel filtration?

I know for a fact that hairgrass will grow in this kind of foam because I have purchased hairgrass from sellers before where it was grown on foam like this. Its also a real bear to get off keeping the plant intact. For that reason I would think you should consider other options.

If you only have 3/4" of substrate I think that is why you are having issues with uprooting plants from shrimp. You should have at the bare absolute minimum 1" of substrate and better would be 1.5-3" of substrate (on the shallow end) depending on the type of plants etc. If shrimp are uprooting hairgrass you probably need to plant it deeper. You could top your substrate with sand/fine gravel if you don't want to buy more controlsoil.
