Tropical Seahorse Liquid Heat SAVES WATER : Reduces water evaporation by up to 50% WARMER POOL : Evaporation accounts for 90% of heat loss from a pool. By reducing evaporation, LiquidHeat helps your pool to stay warmer. ANY SHAPE ANY SIZE : LiquidHeat automatically spreads out over the surface to cover any shaped pool. For heated pools, LiquidHeat helps retain heat in the pool thus averaging a 15% to 40% savings in energy costs. EASY TO USE : Once a day pour the required amount of LiquidHeat into the pool, no cumbersome bubble blanket to remove. SWIMMER AND POOL SAFE : LiquidHeat is totally harmless to all swimmers and harmless to pets drinking from the pool surface. It will not effect the chemical balance (PH, chlorine, alkalinity) of the pool. It will not effect the plumbing or filtration and will not damage vinyl liners or any other type of pool surface in any way.
