Review on 🔬 ACCEL Aquatics BioPellet and Filter Media Reactor FR-30: Enhancing Water Quality Like Never Before! by Katrina Taylor

The design is the best I've seen and tried for biopellets. The downward flow keeps the pellets in a slight tumble by controlling the water flow. It comes with a filter on top to prevent pellets from being thrown out with the stream but I found it unnecessary and removed it. Now I don't have to worry about this filter slowly clogging with fine dirt and needing to be washed. It has a small locking screw on the top that can be removed to add new pellets so you don't have to remove the entire top. It's good, but it's a bit small. I highly recommend this product.
