I was looking for some info on Zeolite release of NH4 and found this:
Controlled-Release Fertilizers Using Zeolites
Interesting.
Seems it woulkd a good thing to add to an aquarium sediment as well in place of plain sand and is pretty cheap.
Makes good filter media as well.
Seems zeolite is a nice addition and could become more widespread in the hobby.
