Create clear, healthy, and biologically active marine aquarium water with Sera Marin Bio Reefclear 100ml — a powerful biological water treatment formulated with beneficial cleaning bacteria and mineral volcanic rock.
The contained cleaning bacteria help break down harmful ammonium and nitrite, supporting safer water conditions for marine fish, corals, and other saltwater inhabitants. At the same time, the mineral volcanic rock helps remove harmful substances, binds cloudiness, and provides an ideal settlement surface for beneficial bacteria.
After application, a brief milky cloudiness may appear. This is normal and indicates that the product is working. Depending on the level of impurities, the cloudiness usually disappears within 4 to 24 hours, leaving the aquarium water clear and biologically active.
Sera Marin Bio Reefclear is ideal for setting up new marine aquariums, regular weekly maintenance, water changes, and after cleaning the aquarium filter.
