The Bioplus 30 ppi sponge is a premium-grade filter media designed to deliver both mechanical and biological filtration in freshwater and marine aquariums. With a density of 30 ppi (pores per inch), it provides the perfect balance between fine particle retention and an optimal surface area for the growth of beneficial nitrifying bacteria.
Ideal for use in internal or external filter systems, the Bioplus 30 ppi sponge performs a dual function: it mechanically traps debris, waste, and suspended particles while also fostering biological filtration by supporting the nitrogen cycle through bacterial colonization.
Its durable, flexible structure allows it to be easily cut and shaped to fit different filter compartments. The sponge can be rinsed and reused multiple times without compromising its performance. For best results, rinse in tank water during maintenance to preserve bacterial populations. The medium-density 30 ppi configuration is especially suited for aquariums requiring both fine filtration and strong biological stability, including community tanks and planted aquariums.
Bioplus 30 ppi is compatible with most commercial filter brands and can be used alone or in combination with other sponges of varying densities for multi-stage filtration.
