I use layers of plastic canvas on the bottom of the tank. The poop falls thru. it works great! You just need to have it cut so there are no rising edges where the crix will climb under and die, also not good for pinheads.
This is without the plastic canvas that I would use for pinheads
here is with PC
here's a closeup of black pc covering soil on a pot.

you can get plastic canvas at any place that sells crafts and it is very cheap - lots of colors, too! It's less than 40cents per sheet.
