Glued Sand Bottoms?

[Funky_Fish14]

Hello Everyone,

I am posting today because im wondering what types of glues and methods people have used to have glued sandbeds. I would like to lay a thin layer of glued crushed coral/large grain aragonite on the bottom of my 75g tank, so that I can have high flow, yet still replicate the sand-bottom look and be able to syphon detrius off the bottom fairly easily.

I was thinking about using silicon, however I think that will take alot of silicon to do. Im not sure what types of glues have been used in the past, maybe epoxy resins? I was even thinking maybe even 'foam in a can' for example 'great stuff'.

Thank-you for any help or suggestions!

Take care,

Chris
