Our Crystal Clear Fountain Lime Solve is designed to safely remove lime scale & calcI'm deposits in all ceramic, cement, fiberglass and resin fountains. Lime Solve water treatment is formulated to deep clean basin pits, cracks & crevices to ensure a new appearance year around and prolong the life of fountain pumps. Weekly applications are recommended for maintenance measures for further removal of lime scale and calcI'm deposits. A complete basin refill with fresh water and application of Limescale Remover every three months is recommended due to continuing water evaporation that most fountains experience. This water conditioner is completely wildlife safe and this 8 oz bottle will treat approximately 80 gallons.
