Paradise makes practical pool and spa care products aimed at the recurring problems every pool owner runs into, with a focus on simple devices that remove a chore rather than add another gadget to the equipment pad.
The best known Paradise product is the Pool Sentry automatic water leveler. It connects to your fill line and holds the pool at a set level, which sounds minor until you consider what happens when the level drifts. A low waterline lets the skimmer pull air, and an air locked pump loses prime, cavitates and can destroy its own seal and impeller. A high waterline is just as bad in the opposite direction, because floating debris passes over the weir instead of being skimmed out.
Evaporation in a hot, dry, windy summer can pull a pool below skimmer level in a matter of days, and it happens fastest exactly when the pool is being used most and least likely to be watched closely. Automating the fill removes that risk entirely.
