What Causes It & Prevention

The build of limescale can be anything from living in an hardwater area, high alkalinity and then other containments such as body lotions and oils. Everyone will at some point suffer with limescale and to prevent/minimise, it is important to maintain correct chemical balances, do not over chlorinate your water, ensure you have correct pH and alkalinity levels.  Cleanliness is key, keep waterline clean by using a soft cloth or an aqua brush and jet wash filters.
