White Diamond 50 Ounces, Removes Toxic Ammonia, Aquarium Filter Media

If you have goldfish, this is the product for you! This product removes ammonia and clarifies the water quickly! Highly recommended product.

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.

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.

I'm using this in my soil mix for my plants. Works kind of like pumice does. It helps remove toxins and odors from the soil.

We bought this to add to our POE water filter - Works well for the purpose, have yet to test to see if it helps with filtration.
