Nothing can ruin your swimming pool experience like a recurring algae problem. For the most part, episodes of recurring algae becomes an issue when it is not completely destroyed with earlier treatments. One common reason for this is poor water circulation in the pool. When this is the cause, the chemicals cannot make it completely around the pool and thus some algae is not killed.
Here are some tips to help you avoid algae problems with your swimming pool.
Anytime you treat your pool for algae make sure that all areas of the pool get a good dose of the algaecide. Some types of algae can live outside the swimming pool and these types will re-enter the water as people and rain bring them back into the pool. One type of algae that can do this is the mustard algae.
The spores of this type of algae can survive away from the pool water for long periods of time. You should make it a habit to submerge your cleaning equipment in the pool overnight as this will destroy any algae that may be on them. Ignoring this step may cause you to reintroduce algae back into the pool the next time you use your tools.
It is important to always read the label and follow the instructions on the chemical that you are using for algae control. One problem with algae is that you do not always see sign of it in the water. This is the main reason to always use the recommended dose for your size pool.
Remember, too, that the algaecide that you use to destroy existing algae is not always the same product you will need to use for preventative measures. Again, read the label to learn more about this.
Pool owners should understand that a major reason for algae coming back is due to poor water circulation. If you see algae appearing in the same places, this is probably the cause.
On many pools the return system is directed towards the surface of the swimming pool. This procedure helps the skimmers collect debris and it gives the pool surface the look of moving water. The downside to this is that it creates dead areas where new, fresh water is not being directed or circulated. This will result in algaecide not being able to reach these spots which means the algae is never destroyed. And this means it will come back at some time.
If possible, turn your returns so that they face downwards or even sideways. This will be a great help when applying chemicals for algae as it allows the chemicals to get to all parts of the pool. Keep in mind that it is helpful run your system for 24 hours a day until the problem is totally gone.
One tip that can be helpful with recurring algae is to run your automatic cleaner more often. This will help deliver chemically treated water to all areas of the pool. Using your cleaner just once a week will make a huge difference in fighting off algae.
