With that knowledge I would feel confident its safe in a litter box. If you used actual kitty litter with it, even if it was harmful you probably wouldn't be using enough to actually harm your cat. **Q: Is this zeolite hydrophobic and is the pore size known?** A: Thank you jwil, for your question! This is a natural product, so the pore size is variable, but the average pore size is 4.0 Angstroms on average, and this product is not treated to make it hydrophobic. Please let me know if you have any further questions! **Q: In addition to ammonia, will it also remove ammonium (produced by Ammo Lock converting ammonia to ammonium) from the aquarium water?** A: I didn't have much luck in regulating in the tank, but I also had removed all stones and natural algae beforehand, so Im not the right one to answer this question **Q: I'm medicating my tank will this interfere with the medication ? Thank you** A: No, this will not remove medication from the water, only ammonia. ## Frequently Bought Together - Marineland White Diamond 50 Ounces, Removes Toxic Ammonia, Aquarium Filter Media - Marineland Black Diamond Premium Activated Carbon, Filter Media For Aquariums, 40 Ounces - DEPEPE 10pcs 7.8 x 5.9 Inch Aquarium Filter Media Bags with Zipper for Activated Carbon, Biospheres, Ceramic Rings --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/2063312-marineland-white-diamond-zeolite-ammonia-neutralizing-crystals-50-oz](https://www.desertcart.us/products/2063312-marineland-white-diamond-zeolite-ammonia-neutralizing-crystals-50-oz) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-27*
