Great quality. My daughter used it for a filtration experiment and it worked great.

We used this activated carbon for my child’s water filtration system science project and it work great the dirty water passed through the filtration system the water did clean the water which it was great . Long lasting as well and the price is great for the amount you get...

Excellent product. I had an odor problem in one of my aquariums. I put the product in a mesh bag and installed it in my aquarium literally within hours no more odor.. great value for the money

I recently tried the Sukh 310g Activated Carbon Pellets, and they worked exceptionally well for my springtails. The quality is impressive, and I've noticed a significant improvement in water clarity. However, the packaging could be more user-friendly. Overall, a solid choice for anyone looking to maintain a healthy environment for their critters!

The pieces of charcoal are larger that the ones that come with many types of filter media. Putting these in a small corner filter worked well because the didn't fall through.

this item arrivede in a very timly manner is being used for oder control which it is doing a fantastic job of.

Produce was exactly as described, worked great.

Good
