Well, we put it off for as long as we could, but it is finally getting hot. As you can imagine, these high temperatures can create problems for swimming pools even when a routine swimming pool maintenance program is followed. Two of the most common pool problems that pool owners experience this time of year due to the heat are cloudy water and algae.
Cloudy water due to water chemistry imbalance
Low sanitizer (chlorine) levels or high pH levels (above 7.6) can cause cloudy water. Professional pool cleaners know the importance of keeping the pH toward the lower end of the ideal range of 7.2 to 7.6—as chlorine is much more effective as those lower pH levels. If you have cloudy water and suspect that it is a water chemistry problem, simply test the water and treat as recommended or better yet, take a pint of your pool water to a professional pool store. They will be glad to analyze your pool water and recommend treatment.
Treating algae in pools
Most algae can be prevented and can usually be blamed on low sanitizer (chlorine) levels. It is much easier and less expensive to prevent algae than it is to treat it. Many pool owners in the Denton area use an algaecide weekly as a preventive measure. This, along with brushing the pool regularly, is very effective in preventing algae.
There are several types of algae that are common in this area. They are as follows:
- Green algae—is either free-floating or attaches itself to the pool surface.
- Yellow (or mustard) algae—usually found in low flow areas of the pool.
- Black (or blue-green) algae—forms a root system which makes it difficult to remove.
Treatment varies with each one of these types of algae, but it usually consists of increasing the sanitizer level, using an algaecide, and brushing the pool.
Increasing main pump run times might also be necessary—most pumps should be operating from 8-14 hours per day, depending on the situation.
As you enjoy your swimming pool this summer, be sure to be aware of the impact that the heat has on your pool in order to avoid problems such as cloudy water or algae.
