Algae floating freely in pool water or growing along the side of your swimming pool liner can quickly tum your pool into a swampy mess. No matter how hopeless the situation may seem, don’t give up on your swimming pool. The right chemicals, along with a little bit of hard work, can quickly remedy your algae problem and return your swimming pool to its original clarity.

Fight Algal Growth: Kill Algae in Your Swimming Pool

It’s slimy, dark and unattractive. It’s algae, and if you’re a swimming pool owner, you’ve probably battled it on numerous occasions. Algae can cause cloudy pool water and leave you embarrassed to have friends over for a swim. Luckily, algal growth doesn’t have to leave your swimming pool looking like a murky cesspit. You can fight swimming pool algae with proper pool maintenance and algae eradication methods.

Monitor Your Swimming Pool’s pH

Proper pH is essential to preventing algal growth in your swimming pool. The ideal pH for a swimming pool is anywhere from 7.2 to 7.8. Investing in a pH testing kit will help you determine how high or low your pool’s pH is at any given time so that you may adjust it accordingly. You can even purchase automatic chlorinators that pump chlorine into your swimming pool at preset intervals to keep your pool at the proper pH when you aren’t around to make the necessary adjustments.

Shock the Pool

Once algae sets in, keeping your pH steady isn’t going to help you get rid of it. The very first thing you should do is to “shock” your pool by introducing roughly five to ten times the standard amount of chlorine to the pool water. It is imperative that neither you nor anyone else swim in the pool until the chlorine levels stabilize. Don’t be alarmed if your swimming pool looks even cloudier after shocking. This is normal and indicates that the treatment was done properly. You may opt to backwash the pool filter after shocking the swimming pool.

Kill the Algae Present in Your Pool

After you’ve properly shocked the pool, you can set about killing any algae present in the water with a commercial algaecide. You can purchase algaecide from your local swimming pool supply store. Like a pool that has recently been shocked, a pool that contains algaecide isn’t suitable for swimming in. Watch out for algaecides that contain copper sulphate. Although these products are effective at killing algae, they are also highly toxic and may present a significant health risk to family members and pets.

Dispose of Algae In Your Swimming Pool

Although shocking your swimming pool and adding algaecide kills algae, you still need to get rid of the dead algae before your pool is suitable for swimming. Using a pool brush with a long handle, brush the walls and floor of your swimming pool vigorously. Take care to brush even areas of the pool that appear to be clean. Algae are microscopic and invisible to the naked eye until they begin to grow and multiply. If you have a vinyl lined pool, it is important to use only a soft-bristled brush. Wire-bristled brushes are only safe for use with concrete pools and can easily damage vinyl. Vacuum the swimming pool after cleaning. If the algal growth in your pool is severe, however, you may need to drain your pool entirely before cleaning the walls. If you do so, rinse your swimming pool liner well before filling your pool with fresh water.

Once you have taken all of the necessary steps to kill and dispose of the algae in your pool, you can focus on preventing further algal growth. Test your pool’s pH level daily and adjust the pH as needed. Keep the pool clean through regular brushing and vacuuming. Backwashing the filter periodically disposes of any algae that take up residence in the filter and prevents them from migrating to your swimming pool. Should an algae problem arise, treat it immediately rather than allowing it to get out of hand. A clear and beautiful swimming pool provides your family with a backyard paradise that is well worth the effort you expend to keep it clean and healthy.
