Fine beach sand. I use the stuff I find in a local freshwater and have great success with this method; a few folks around here use it with equal success with crypts, some quite rare.

Rs,
I have tried local freshwater sand too on minima, affinis and parva. Other then parva, the other two didn't grow well. When I digged the bottom out, I find that the roots are rotting and there are evident of anaerobic activity underneath. Was wondering whether the sand was too find and hence oxygenation to the bottom is poor.

By the way, although both are plants from same origin. Thier flower twist in different directions. Is that normal?

You have to put a thin (12mm) layer of well composted manure under the sand. And you need to soak the manure in water for a couple of weeks first. If you don't, you can expect yuckyness for a while, then it settles down ad grows crypts better than anything I've ever seen.

Just to clarify. You soak all the manure before you set up your pot or you set up your pot with manure in it then soak it? Thanks for sharing.
