Influences On Water Quality
Although there is less water in a spa than a pool, that doesn’t mean a spa is less care. Actually a spa requires more specialized water treatment to keep it sparkling, clean and healthy.
Rain and lightning
Contaminants can be introduced to your pool water from rain run off and air pollution. These contaminants can alter the pool’s chemical levels, effecting the water balance and sanitation. Lightning does not affect the water’s chemistry, but it is advised that you do not swim during storms.
Using bore water may stain your pools. You can try to stop this staining by using met-sequestering agents, otherwise known as chelants, or metal out.
A pool blanket allows more of the heat absorbed by the water to be retained when it gets colder which can have an effect on water balance and chlorine decomposition.
Shutting down your pool over Winter
If you stop using your pool over Winter, no chemical adjustments are required. However, if your pump and pool equipment are still running you will still need to monitor the pool’s sanitation and water balance. If your unused pool is allowed to turn swampy, it may cause staining and other problems which can be costly to restore.
