White diamond removes up to 4 times more deadly ammonia to keep water clean and fish-safe. It protects against sudden ammonia spikes and helps control the presence of ammonia...especially during the break-in period. Review: Good product. - It helps to keep my fish tank clean, the NO3 levels are finally coming down. Tip: put the recommended size( I use about a tablespoon) in a mesh bag, rinse, then place the bag into the filter. That way the water doesn't get cloudy. Review: Happy koi fish - Perfect for what I needed. My koi fish have been spawning (twice on the spring). I placed a mesh sack full of zeolite in the pond. The water quality and ammonia disappeared overnight...Great for outdoor ponds too. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002566XS | | Brand | MarineLand | | Brand Name | MarineLand | | Customer Reviews | 4.7 out of 5 stars 2,971 Reviews | | Global Trade Identification Number | 00047431901421 | | Importer Contact Information | ATM RETAIL 1st Floor Beside P and T Building Lakdi Ka Pul Hyderabad Telangana 500004 | | Item Form | Granules | | Item Weight | 3.13 Pounds | | Liquid Volume | 10 Gallons | | Manufacturer | MarineLand | | Manufacturer Part Number | PA0382 | | Model Number | PA0382 | | Pet Type | Fish | | Target Species | Fish | | UPC | 047431901421 | | country-of-origin | USA | ## Product Details - **Brand:** MarineLand - **Item Form:** Granules - **Item Weight:** 3.13 Pounds - **Liquid Volume:** 10 Gallons - **Manufacturer:** MarineLand ## Images ![Marineland PA0382 White Diamond Ammonia Neutralizing Crystals, 50-Ounce, 1417-Gram - Image 1](https://m.media-amazon.com/images/I/81pu5mdAwZL.jpg) ![Marineland PA0382 White Diamond Ammonia Neutralizing Crystals, 50-Ounce, 1417-Gram - Image 2](https://m.media-amazon.com/images/I/81qBhjRfuDL.jpg) ![Marineland PA0382 White Diamond Ammonia Neutralizing Crystals, 50-Ounce, 1417-Gram - Image 3](https://m.media-amazon.com/images/I/81FUMwCCX4L.jpg) ![Marineland PA0382 White Diamond Ammonia Neutralizing Crystals, 50-Ounce, 1417-Gram - Image 4](https://m.media-amazon.com/images/I/813b-GsUHuL.jpg) ![Marineland PA0382 White Diamond Ammonia Neutralizing Crystals, 50-Ounce, 1417-Gram - Image 5](https://m.media-amazon.com/images/I/81OIFZZ--fL.jpg) ## Questions & Answers **Q: can i use this to deodorize a cat litter box?** A: I would guess it would be fine, if its safe for your fish in your fish tank where fish will die if you breathe on them wrong its probably safe in dry form in a litter box. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product. *by A***O on 23 October 2026* It helps to keep my fish tank clean, the NO3 levels are finally coming down.
