Review on 🐠 Enhance Water Quality with Acurel Extreme Activated Filter Carbon Pellets for Aquariums and Ponds by Robin Williams

I use Drinkwell Stainless Steel Pet Waterer with reusable filter for Drinkwell 360 + 3 month supply of charcoal. These charcoal pellets work great. Some people complain that other charcoal grains are too soft. They are almost identical to the ones that originally came with my filter. I chose the 100 oz (6¼ lb) size because it's very economical. Charcoal pellets last forever and have no expiration date. Since purchasing a reusable filter, I've decided it's more economical to go without filter cartridges. Simply fill the cartridge holder with this granulate. Some screen material, cut to fit at both ends, done!
