I hope they do and am anxiously waiting for any reviews. I've been using bio-pellets on one of my systems for the past 4 years that is heavily stocked with fish and have tried about 5 brands. They all do reduce No3 but as for Po4, not one drop in my situation. I understand the Redfield Ratio concerning bio-pellets but none of the different brands that I have used reduced any Po4 at all.
I will say that as an ongoing pellet user, I do prefer Eco-bak over any other brands that I have tried. They do not clump and tumble well even as the amount diminishes.
like mbg75 said all the time , u have to balance, then NO problem.
