Review on Kolar Labs Premium Catalytic Activated Carbon: Tap 💧 Water & Aquarium Chlorine, Chloramine, and Hydrogen Sulfide Removal by Sarah Riekhof

I first bought a pre-filled cartridge for my RODI system and it was perfect. When it came time to replace it, I bought a small container, thinking it would be fine for refilling the cartridge. Not even close! When Kolar Labs reads these reviews I'd like to suggest listing the volume of each size so a guy like me knows how much is in a cartridge and how much is in a small or medium sized container. That would definitely help! And that, 4 instead of 5 stars. Great product, why the puzzle of how much catalytic carbon is in a different sized container?
