Review on Marineland White Diamond 50 oz - High-Efficiency Ammonia Remover for Aquarium Filters by Dan Husband

Like many others, I have used this in litter boxes. I have several cats and this really helps keep the smell under control. I use it with Dr. Elsie's clumping litter and dig up the boxes about 3 times a week. The most important thing is to dig regularly so you don't end up with a box full of poop all over the house. This product helps neutralize the odor of the litter, which is non-sticky but still retains some urine. You know how the linens gradually darken until you've completely replaced all the fresh linens? This will help get rid of the smell until it reaches that point.
