Neat! I do intend to keep a heavy bioload and not saying I feed a lot, i just like feeding a variety of things. My system *should* be easy to control but is hasn't been. My nitrates could be in the 400ppm range for all I knowBioPellets are certainly still relevant today.
But they're APPLICATION SPECIFIC.
BP work best in high load aquariums where it's very difficult to otherwise control the nutrients.
Countless numbers of service techs use BP to keep nutrients in check on aquariums in commercial settings such as public displays...
In fact several LARGE public aquariums use BP in their displays.
