Ecosavr Solar Fish Liquid Pool Solar Cover 3-Pack
The Ecosavr Solar Fish are an effective liquid solar pool cover that greatly reduce heat loss and evaporation from your exposed pool surface. The small disposable plastic fish contain a Heatsavr liquid that is dispensed through a valve in the fin and is undetectable by swimmers. The safe and biodegradable liquid then forms a transparent layer on your pool to inhibit heat evaporation keeping your pool at a desirable temperature! One Ecosavr Solar Fish will cover 15,000 gallons, for approximately 25 - 30 days; Two Ecosavr Solar Fish are required for larger pools.
