Simply fill a bucket with pool water and put it in the pool so that the water level of the bucket and the pool are the same. If the water level in the pool is lower than the water level in the bucket after one week, you probably have a leak. This method is relatively reliable, because the condensation behavior is the same in both tanks.
Usually, algae is not hazardous to your health. Although algae might not present a health risk, it can make the water cloudyand your pool look dirty, thus negatively impacting your pool enjoyment. Your constant chemical cleaning can reduce the amount of algae in the pool. If that does not help, you should contact a professional cleaning service. We would be glad to provide you with this service.
Many systems require you to change the water, even though the water quality is still very good. Automatic systems are able to analyze and reduce your consumption, but many modern filter systems are so effective that the water has to be replaced much less frequently. We would be pleased to assist you in this regard.
