Great product to control ammonia levels in your fresh or saltwater aquarium. I mix it 50/50 with activated charcoal for my filtration packs. Works great

great for the price and you get a pretty large container. Please keep in mind this will work to reduce ammonia but you still need to take care of the original issue of where the ammonia is coming from. But to keep it down this works very well

I've been using this Marineland White Diamond 50 Ounces filter media for 10 yrs or so. I do mix in some charcoal media in with it when refilling my media bags for my 50 gal. aquarium pump and filter. The water stays crystal clear and the fish stay healthy. Our balloon belly molly fish just keep on having babies, have to give them away. An unhealthy tank, fish won't reproduce. Sure, we lose a fish every now and again, but the average life span of these mollies is 1.5 to 2 years. So with them having babies, we haven't bought any new fish in the last 10 years. This media is doing it 's job with regular aquarium maintenance. Very pleased with this media. $5.29 for 50 ozs. will last me about 2 yrs.

Really keeps my water fresh and clear. Because I have fancy goldfish, they can be rather dirty. I do a partial water change and fill up my filters with this once a month.Be sure to rinse off before putting it in!

My dog potties in rocks by pool. Very unpleasant. I sprinkle some of these crystals along rocks and it takes care of most of odor. Sunshine renews the crystals.

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.

We use this to refill the up tube filters (which are not intended for refilling) and the size C Marineland filter cartridges. I wish there was a B size option too.

I love this product and Fluval. Fluval is way more expensive per pound. It’s $99 for 6 lbs. this is only $6 for 3.2lbs. Math checks out. Both works well. Make sure to rinse before you use. I use a fine mesh bag that can hold Purigen and it works well.

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.

A nice price for a nice amount. Got here easily and performs like a higher grade ammonia buffer.
