Pure Reef Balance 60 Balls - Evolution Aqua

Directions Use 1 Reef ball per 25 litres of aquarium water every 2 weeks. Place the balls directly into the filter section or sump. For best results place in an area of water flow. The balls can be used in filter socks and net bags. 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.
