## Description

White diamond ammonia-neutralizing crystals are ideal for all freshwater aquariums and ponds. 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: If you have goldfish, this is the product for you! This product removes ammonia and clarifies the water quickly! Highly recommended product.
Review: 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.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by A***R on 28 November 2024*

Great for filters to remove ammonia in case of spikes but that isn't why I got this stuff. No I got it for cat urine. Specifically to get rid of the ammonia smell from cat urine that soaked into a carpet. I took some of this stuff, a towel, a hammer, and some concrete and powdered it and then rubbed it into the carpet (which had already been cleaned with enzymatic cleaner but still smelt vaguely of ammonia). I then left the carpet folded up outside for 12 hours in the sun. Bam! No more ammonia smell. Baking soda has NOTHING on the raw power of zeolite. I put a bunch in little mesh bags to leave in my cupboard that has a litter box in it and it works great to keep any smells down. This winter I shall be using the rest to hopefully help my filter clean the ammonia out of my small duck pond during the time when I don't have running water to the coop and the ducks spend the night sleeping in it.
