I went the other way, started with sand PDZ mix, then couldn't find not dusty sand.It will go on the poop board. I like the pdz that is there now. It will stay but it is a little too thin in spots. I'm going to try a mix of sand and pdz because sand is so much cheaper. Even if you have to buy it.
Now use all PDZ.
I keep it thin (<1/4") and sift all of it every day.
Here's some posts about it, they're kind of old, but changes are noted.
...and the threads these posts are in has a ton of examples of poop boards.
