Vertex Bio Pellets vs. NP Pellets what is the difference

[chris121277]

Don't mean to hi-jack your thread.....but I wanted to know, out of everyone here who is now running these type of pellets......did you see a noticeable difference from before you starting running them to after?


I guess what I'm getting at is it worth buying another reactor and running 3? (1 carbon, 1 phos remover and 1 bio pellet)
