Would this mix of substrate be like the ABG from josh's frogs? I found this mix on another post for a viv but the tank didn't house frogs.

2 Parts Potting mix peat moss http://www.bunnings.com.au/potting-m...31344_p3010202
2 Parts Cocofibre
1 Part pine back http://www.bunnings.com.au/mulch-pin...-4040_p3010176
1 Part Hort charcoal http://www.bunnings.com.au/soil-impr...30288_p3016175

Also would this spray foam work and is it safe for the frogs? http://www.bunnings.com.au/filler-ex...-foam_p1211402

Thanks!
