Firewater, I made this thread basically just for results and discussion so its fine. I think the pellets have really helped with the removal of phosphates and nitrates but the zeo products have only intensified the results. The zeobak is what I attribute the fast reaction of the pellets to. The rest has just been amazing.As for GFO and carbon go, I only run carbon because the phosphate removal by gfo would alter the results of the pellets.
