Increase the flow around your biological media helping to improve biological filtration, plus keep your block neat, tidy and easily accessible.
Need more than one rack? Bio Stackers are modular, meaning Bio Stackers can be stacked on top of each other when adding extra blocks or if you simply have more than two.
