I read that activated carbon will eliminate litter box odor when added to clumping litter.** A: It probably will work, it has carbon to neutralize odors and a way to trap ammonia (urine has a pretty fair amount of ammonia.) It's certainly not going to hurt to try it, the cat might even enjoy a frangrance free box. **Q: Is this type of carbon better than the regular Diamond Blend Activated Carbon?** A: The blend of carbon and zeolite (the white stuff) increases the amount of ammonia absorbed and gives you a better range of capacity of a fish tank. It also extends the time between water changes, but I would only use that extra time for times when you can't clean the tank at the normal time. It gives you a safety margin and for that reason alone its worth using. You dont have to use it, but it's a better way to go. **Q: is this more dust, pellet or grain in texture?** A: Grain it is more ammonia crystals than carbon. If you want a 50/50 mix buy some more carbon. **Q: What are the ingredients, is it just activated carbon and zeolite? Or are there other additives?** A: Hi Annette,The label doesn't list anything except premium carbon. There is a side label on each side but it is not written in english. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This product TOTALLY eliminates the smell of cat pi$$, in a room with a litter box! *by 6***S on 29 October 2020* ### ⭐⭐⭐⭐⭐ Use this to accomplish less maintenance in the fish tank. *by T***S on 11 March 2026* ### ⭐⭐⭐ Bottle with cracked holes *by T***. on 3 August 2024* ## Frequently Bought Together - Marineland Diamond Blend 50 Ounces, Ammonia-Neutralizing Zeolite And Carbon, 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/409762450-marineland-diamond-blend-50-ounces-ammonia-neutralizing-zeolite-and-carbon](https://www.desertcart.us/products/409762450-marineland-diamond-blend-50-ounces-ammonia-neutralizing-zeolite-and-carbon) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-15*
