Review on 🐠 CNZ Media Filter Bags: Premium Activated Carbon Charcoal for Effective Filtration - Perfect for Aquarium Fish Tanks, Ponds, and Canister Filters - 4 lb, Black C4PK by Crystal Mack

Revainrating 2 out of 5

NOT recommended for use in water, especially for fish.

Not sure about this granular charcoal. We used it in our fish camp to hopefully clear the water and remove the lingering haze we were having. After installation we had problems with dead fish and the water remained cloudy despite being in our filtration system which goes through all the water several times a day. When we removed the bags of coal, the dying stopped. Not recommended for use in water.

Pros
  • Durable finish
