Brightwell Aquatics Xport-BIO Block Filter

Upgrade your filtration capacity with Brightwell Aquatics Xport Bio Brick, an ultra-porous biological filter media block engineered to maximize beneficial bacteria growth and improve nutrient processing in reef, marine, and freshwater aquariums.

Constructed with advanced open-pore technology, the Xport Bio Brick provides massive internal surface area for colonization by nitrifying and denitrifying bacteria. This helps convert toxic ammonia and nitrite while also assisting with long-term nitrate reduction in established systems.

Ideal for sumps, canister filters, rear chambers, and custom filtration setups, this durable bio media block supports stronger biological stability, cleaner water, and healthier livestock.
