The slow release capability of the Supa Neutravitaliser Block is designed to buffer and neutralise the acidity of aquarium water.

Suitable for use in vivariums, cold water and tropical aquariums. Each block will last for up to 2 weeks in a 45 litre aquarium, assuming a water temperature of 20°C - 25°C. Lower temperatures or highly alkaline water will inhibit dissolution while higher temperatures will accelerate it.

When placed within a terrarium or turtle/terrapin enclosure, the block provides a health boosting calcium rich environment.

Typical Analysis: Calcium Sulphate 95%, Calcium Carbonate 5%.
