Review: WATER IS SO CLEAR OVERNIGHT! - 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!
Review: Use in all my tanks - I use this in all my filters instead of buying premade filter bags. This has carbon and zeolite to elevate the water quality and reduce ammonia. It is a more economical way to filter my tanks, and I have also more control over the quantity of carbon/zeolite. I purchased filter bags and I make/fill to my needs. This is a great economical way to filter my tanks. The container size will last me for a long time.

## 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.
