Review: I used this for almost 4 years for my 80gal tank. To make my own filter stuff. Works good easy to use. Washes very well and not much colour run off. Helps keep water clear and clean for sure. Good value for money at the time I bought it. The dual mix with carbon is nice so I don’t have to have two containers and mix together. Not that mixing is hard but is convenient.
Review: I scoop out my cat's litter box daily. Even so, unless all the litter is dumped and replaced, a subtle, ammonia based smell of the contaminated litter continues to permeate the air in the room. I found this product, and purchased it in hopes of "fixing" this problem. And it WAS a problem. Especially if that odor is in close proximity to bedding, fabric window coverings, furniture, and most importantly, otherwise "clean" clothing you intend to wear. In my case, dress shirts, suits, and ties, hanging in a closet. I didn't fully realize this until a coworker I went to lunch with, asked me if I owned "a cat." Or "cats." Ugh! "Embarrassing", is an understatement. I guess I was just used to it, and didn't even really notice it, or think it was an issue. But trust me, people around you DO notice it, and it IS an issue. Few people will be kind enough to actually say anything to you about it. And I'm glad he did, because as embarrassing as it was, by doing so, it prompted me look for a way to solve it. Moving the litter box, or getting rid of my cat, were NOT options. So I gave this zeolite ammonia neutralizer a shot, and it worked like a champ. It's actually pretty powerful stuff. I started off with fresh litter, and every time I scoop it out now, I sprinkle the equivalent of what will fill up the average laundry detergent bottle cap. Right in, on top of the litter. The difference it makes in preventing the odor is nothing short of incredible. The absence of the smell in the house now, is definitely noticeable. I've since had everything in the closet RE-dry cleaned. And my coworker says I no longer smell like I slept at the local animal shelter before work. This is an OUTSTANDING PRODUCT if you have a cat, or cats. : ? )

## Questions & Answers

**Q: Has anyone used this in a cat litter box? 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.

Excellent product, works very well. I used it as aquarium filter media--placing it in THE MIDDLE OF an Aquatic Experts Aquarium Filter Floss for Fish Tank Filters - FilterFirst Aquarium Filter Pad - Media Roll for Crystal Clear Water THEN PUT THEM IN Aquarium Filter Media Bags with Zipper for Activated Carbon, Biospheres, Ceramic Rings. WATER IS SO CLEAR OVERNIGHT!
