Natural mineral care, explained. Every Arden Line product is built around one remarkable material: natural clinoptilolite zeolite. This guide covers what it is, the science behind why it works, and how to put it to work for your flock, your garden, your houseplants, and odor control around the home.

What is zeolite?

Zeolite is a family of natural minerals formed when volcanic ash settled into ancient lakes and seas and crystallized over thousands of years. Ours is clinoptilolite — the most useful and well-studied type — mined and milled in the USA at 85–95% purity, with no crystalline silica.
Under a microscope, each grain is a rigid honeycomb of microscopic channels that packs roughly 24.9 m² of surface area into a single gram — the reason it does so much with so little.
Why it works: the science
Zeolite’s framework carries a natural negative charge, and that charge does two jobs at once.
Traps odor & ions
A very high cation-exchange capacity (CEC ~180–220 meq/100 g) locks onto ammonium — the source of ammonia odor — plus potassium, calcium, and heavy metals.
Holds water & nutrients
The honeycomb channels soak up moisture and loose nutrients — over 55% of its weight in water — then release them slowly over time.
Lasts a long time
A hard, low-clay mineral (Mohs 3.5–4) that resists breaking down, so it keeps working season after season.
How to use it: Backyard chickens
Zeolite earns its keep two ways — as a soft, finely milled dust bath that helps hens keep feathers clean and dry, and as a coop and run treatment that absorbs droppings moisture and locks up ammonia.
- Fill a tub or dust box a few inches deep with Fine Dust and let your flock do the rest.
- Sprinkle Fine Dust or Granular over coop floors, droppings boards, and nesting boxes.
- Refresh as needed and replace when soiled.

How to use it: Garden & soil

Mixed into beds and potting soil, zeolite improves drainage and aeration while acting as a slow-release reservoir for water and nutrients — reducing how often you water and how much fertilizer leaches away.
- Blend Granular into the top 4–6″ of soil at roughly 1–2 lbs per square yard, or about 5–10% of a potting mix.
- For raised beds and new lawns, work it in before planting.
- Top-dress with Regular grade around established plants.
How to use it: Succulents & houseplants
Succulents and cacti die more often from too much water than too little. Zeolite gives a fast-draining mix that never stays soggy — while its channels hold a small moisture buffer that evens out the wet-dry cycle.
- Blend Granular as one-quarter to one-third of a gritty succulent or cactus mix.
- For pothos, snake plants, orchids, and bonsai, mix a handful into the soil for better aeration.
- Add a thin layer of Regular as a top dressing — it looks clean, helps deter fungus gnats, and won’t grow mold.

How to use it: Odor removal

Most coop, barn, and litter odor comes down to ammonia. Zeolite traps ammonium before it becomes airborne — capturing the smell at its source instead of masking it. Set out an open container or sprinkle it where odors start:
- Litter boxes, kennels, and small-animal cages
- Compost and worm bins (it also conserves nitrogen)
- Trash cans, mudrooms, basements, and damp closets
