Review on 🐠 ZORB Filtration Media: Versatile Aquarium Filtration Pouches for Canister Filters, Ensuring Clear Water and Detoxifying Harmful substances for Fish by Andrew Camlin

Bought to rid our KOI aquarium of tannins. This was due to a lack of knowledge that home-bought driftwood can contain these bacteria. Well, this tank is built to look natural. The bacteria are so big that the color of the water is not like tea but like dark chocolate. Instead of draining the tank, I use this product along with frequent water changes. I'm hoping to deplete the TANNINS with H2O changes and for the BioChem Zorb API to remove them from the driftwood. I recommend using this product.
