For higher bio loads, additional BIO-FX can be usedWhy is it recommended to replace half the biological media every six months? Will I disturb my cycled aquarium by doing so?Over time, the pore structure of various biological medias can become clogged with debris and as such cannot be colonized by nitrifying bacteria species. We recommend replacing half of the biological media every six months in order to maximize the surface available to these bacteria. Doing so will have have no effect on a cycled aquarium.Whats the difference between Biomax and Bio-FX?Bio-FX nodes are larger and contain a greater surface area for beneficial bacteria colonization.
