I have been running well OVER the "recommended" amount of pellets for a few months now (since September) without any issues. In theory you can't over do it with the pellets. Bacteria will consume what pellets are available. If you have more pellets than bacteria then the pellets should simple deplete at a slower rate. I recently added more pellets and a second reactor
. I'm probably running close to 2 or 3 times over the published recommended amount. I really like that I don't have to touch the reactors for months on end.
In both my reactors I have a mix of the original NP Biopellets and Vertex pellets. I have not seen any NP Biopellets sold locally recently so I'll prob just stick to the vertex. I do like that the pellets are smaller and tend to tumble easier.
On the flip side, some people are still reporting issues with their use of pellets. So, if you are at all concerned or hesitant definitely follow product recommendations rather than being cavalier like me
