Zeolite for canister filter

Hi, Just wanted to ask members if they have used Zeolite as a filter media in their canister filters. Zeolite claims to be densely rich in mineral content which helps plants and said to be effectively removing poisonous chemical compounds like ammonia. Also said to help nurture beneficial bacteria in their course surfaces. I simply tried putting them into the tank after washing them. But immediately some of them started like dissolving in the water and made water some what cloudy. But it settled quickly. So I have my own reservations putting them into the canister filter after seen that.
Please educate me on this matter. Many thanks.

Could be counter productive in a planted aquarium considering many dose Urea & NO3.

Zeolite is safe to add to aquariums. However, the claims you read seem to be an advertisement rather than fact. Adding Zeolite will not feed your plants minerals. It will however remove ammonia and organics just like activated carbon. That's about all you can expect for a few weeks. After it has adsorbed all it can bacteria will colonize and it will become nothing more than a bio-filter. It's not some sort of magic bullet despite claims by manufactures.

Instead of relying on zeolite, carbon or any other chemical to remove ammonia and organics try changing the water.
