Maintaining a swimming pool can be a real headache in summer months, with green algae threatening to take over unless you use high levels of chlorine and chemicals. With this solar purifier you can reduce the amount of chemicals you use, getting rid of the chlorine smell, saving money and still keeping the water clear. Powered by small solar panels, it works by ionizing the water which inhibits algae growth. It is quite an expensive investment, but pays for itself over time with the reduction of chemicals needed. It does need regular weekly cleaning to keep it working efficiently, so is not totally labor free, but is worth it for most people to swim in clear water without the chemical overload that is so bad for skin, bathing suits and the environment.
