Re-Fresh will give you fresh sparkling water in your aquarium by reducing organic waste from fish and organisms in tank water, which not only unsightly but can also disrupt the health of the aquarium’s ecosystem. Proper dosing can revitalize old, green/brown water, preserve clear water, and keep water odor-free and crystal-clear. For best results, we recommend adding Re-Fresh on a weekly basis with a maximum dose of 5 ml per 10 gallons of water to maintain a clear, clean, sparkling aquarium that enhances fish, organism, and aquatic plant health. The condition of every aquarium varies, so it may be necessary to add Re-Fresh more frequently (every other day) to achieve desired results.
