Great product, my aquarium was starting to get a bit hazy, this cleared up the problem in just a day, it did take any prerinsing so it saved a little time.

    • Reasonable price for a good product
Size: 22 ounce
Small enough without falling out of the media bags. Appears to be working very well reducing the smell and cloudiness in the water

Great Carbon to filter the aquarium water after you provide medication to treat your aqua pats. always a good idea to have a medication treatment tank to isolated your aqua pets for treatment.

    • Probably excellent for aquariums, good not great for off-label odor-removal uses
Size: 22 ounce
Bought this so I could de-perfume a secondhand dresser I bought. I think it did a fair job, although I did set the drawers out in the sun so that did a lot of the work. One drawer has been resistant. However, I also had a plastic spray bottle that I'd previously put mint oil in when spraying to deter insects (mint oil spray: moderately effective) and had been unable to get the mint smell out of. I filled it with a third of a cup (sprayer holds about 2 cups) of charcoal and seems to be very effective. So, I think you would need a lot to de-stink a drawer, but this does work like the fancy charcoal being sold. Someone had mentioned that you should buy the charcoal powder. However, it *is* charcoal so black dust will get everywhere, be careful. Finally, I am using this off label so I don't want to give it fewer stars for that reason. I am sure it is good for aquariums. ... show more

    • Works as it should!
Size: 22 ounce
I love this. Its cheap and comes with a lot! I can keep refilling my filter net. I do this monthly so its perfect to have a big amount! Recommended for sure! Be sure to rinse in water after adding to filter net because it will release dark dust from the rocks.

    • Cat Litter Robot's friend
Size: 40 ounce
*I love this stuff & as a pet parent keep it on hand at all times. Back in my fish keeper days it was a must have (& will be again when I get around to reviving my aquaria passion) for now I use it in my cat litter odor mix* Cat Litter Robot's friend We use a Litter Robot & needed an extended odor additive due to the litter lasting longer than your normal pan litter. I am very happy w/ the longevity, smell, dust level, weight, clumping speed/hardness, poop odor blocking, ammonia blocking, etc of our current set up. We have 8 cats, all fixed, 2 boys & 6 girls. 2 Litter Robots (adding a 3rd next year), a tote litter box, & a short tote litter box in their isolation enclosure. W/ this setup we only have to change the litter in the Robots if one of the cats get a sick tummy or when we do a deep clean on the Litter Robot itself. The pans need a full empty maybe every 2 months. Our mixed litters - roughly 4-6 boxes every 2 months: Purina Tidy Cats Lightweight 4-in-1 Strength Clumping Cat Litter Purina Tidy Cats Lightweight Glade Extra Strength, Scented, Clumping Cat Litter Our additive mix (Literally just dump all of the below in a little tote & shake it) - one batch lasts roughly 6 months: Dr. Elsey's Ultra Litter Attractant, .56 Kg / 20 Oz (Pack May Vary) Fresh Step Cat Litter Crystals - Cat Litter Box Deodorizer Product for All Cats - Combats Cat Odors and Neutralizes Smells - Multiple Scents and Size Packs - Cat Box Deodorizer, Litter Deodorizer - 3 pack Ultra Pet Clumping Crystal Cat Litter, White Crystals with Multicolor Crystals, 5 Lbs Nature's Miracle Just for Cats Odor Destroyer (x2) Marineland White Diamond 50 Ounces, Removes Toxic Ammonia, aquarium Filter Media MarineLand Diamond Media Premium Activated Carbon, Blacks & Grays, 40-Ounce (PA0373) ... show more

    • Resolved Cat litter smell

I use this in my cat litter in my automatic litter box! I mix it in the litter refill area and in the main litter area and now I don’t smell anything when in walk by the box. Before, I could smell the used litter in the bin when I walked by! I am so glad I found out about this trick. I wish more people knew. ... show more
