Been playing with Zeolite as a soil improver. I had some layng around as a safe guard for ammonia spikes in the AP system. Zeolite sucks the ammonia out of the water. It can be discharged again with high levels of salt.

A big problem in soil gardens is once the fertilizer has moved passed the root zone(half a mtr ish) its gone. Some plants and trees can use it but for most it is out of there reach. Adding zeolite to your soil mix helps keep nutrients in the root zone. I like to soak the zeolite in a fertilizer mix first before adding it to the soil. Similar to pre-loading Biochar so it does not take it from the soil when its first added. You can get bags of Zeolite from most pool shops as it is commonly used in sand filters.

As I was reading through your post I was thinking "but what about charcoal". Then you mentioned it towards the bottom...

Charcoal is good stuff, works a lot with surface area but breaks down over time. Zeolite will suck up ammonia and is recomended to use with Urea so the bacteria in the soil must still be able to work it. Was toying with the idea of using it as a AP media if it could be sourced in larger sizes. High levels of salt cause it to discharge the ammonia but not sure what levels that would be. You may end up with a system that does not get ammonia spikes and works like a battery. In winter when the fish slow up there is still nitrates that the roots can get to. Easier to buy a bag than making biochar.
