Tips for Preventing and Eliminating Algae in Your Pool

Posted on: 25 August 2015

One of the most common problems with backyard swimming pool maintenance is dealing with algae blooms. If the water isn't properly sanitized or the filters aren't getting the job done, algae blooms can thrive. Algae spores can come from many different places, including debris introduced to the pool from the wind or spores that are on your body when you get in the water. While there aren't any completely guaranteed methods to prevent and eliminate algae, here are some of the swimming pool care tips that can improve your odds.

Start with Prevention

A good offensive care approach is the best way to keep algae at bay in your swimming pool. There are a few steps you can follow to make your pool less algae-friendly.

  • Chlorine Treatments – Make sure you're keeping up with your chlorine treatments at all times. Chlorine is a sanitizer, and it can help to prevent algae spores from thriving in the water. Make sure you're applying chlorine treatments each week, and add some floating chlorine tablets to the water regularly for added protection.
  • Cleaning Up – Keeping up with your routine skimming every day is an important part of preventing algae. When you leave debris in the water, it causes the chlorine in the water to deteriorate, because that chlorine has to focus on getting rid of the contaminants in the water. Skim the pool once a day and make sure you're clearing the filter basket daily, too.
  • Filtering the Water – Keep your pool pump and filter running for at least eight hours every day. This eliminates particles that are in the water. The longer fine particles are left in the water, the greater your chances that those particles could be a food source for an algae bloom. Inspect the filter cartridges regularly, and replace them as needed to keep them clean.

Be Aggressive about Treatment

If algae does appear in the pool, you're going to need to address it right away. The sooner you treat the water, the better. Start by brushing both the sides and the bottom of the interior pool surface. This is essential, because it breaks any spores loose that may be clinging to the sides. You'll want those spores distributed in the water to treat them effectively.

For algae that's formed a thick layer over the top of the pool, you'll want to use the vacuum and clear out that thick covering first. Once that part is complete, treat the water with a commercial swimming pool shock treatment. This is a high concentration of chlorine that will help eliminate the algae. Once you've applied that according to the product's instructions, treat the pool with an algaecide. Avoid swimming for the period recommended on the algaecide, since the waiting time is different for each product.

If these tips don't help, or you're not comfortable tackling an algae bloom on your own, talk with a swimming pool care specialist like Aquatic Pool Plastering about having it professionally treated.
