Pure Reef Balance Marine Filter Balls

£14.99
Pack of 3 x 20 gel marine filter starter balls
Use 1 PURE Reef Balance ball per 25 litres of aquarium water, every 2 weeks. Place the balls directly into a filter section or sump. For best results place in an area of water flow. PURE Reef Balance is also suitable for use in filter socks and net bags, fluidised reactors or refugiums.

Once in the filter, each PURE ball will release beneficial bacteria into the water, shrinking as it does so. A small white bead will remain once the ball is spent. This can be left in with biological media where it will add to the bio mass, or removed and replaced with new.
Frequent use of PURE Reef Balance will help maintain biological equilibrium and prevent bacterial monocultures from forming in aging filters, live rock and sand.
Average contents 60 balls, which will dose a 250 litre saltwater aquarium for 12 weeks.
