I used it a couple of years ago.
Repotted out of it pretty much the next year.
Problem for me is it stayed too wet and then went too dry. Because my other trees were in an open mix and I didnt have time to remember which trees needed less water than the ones in diatomite and crushed marble chips.
I dont find Zeolite holds too much water if its with other really open materials.
The real problem with Debco was if it dries out, then its a real bugger to get wet again.
All trees potted out of it had roots around the edge of the pot and nothing in the middle.
Its unlikely you will kill your trees just because of the soil mix, but you must adapt your watering and feeding schedules.
I prefer a much more open mix.

Aikido keeps me rolling; Bonsai keeps me still.
