Common Causes of Algae Buildup and How to Prevent It Happening Again in Your Central Florida Pool

Algae in a swimming pool can be more than just a cosmetic issue. It's a menace, turning that sparkling oasis into an unsightly, swamp-like mess. Worse, if left unchecked, algae can create a health hazard, making pool surfaces slippery and possibly harboring harmful bacteria. But how do algae end up in your pool in the first place, and how can you get rid of it and prevent it from returning? If you're in sunny Central Florida, where pools are a must-have, this is crucial information.

The Algae Invasion

Algae are microscopic, plant-like organisms that come in several varieties, including green (the most common), yellow or mustard, black, and pink. They can multiply rapidly, especially under ideal conditions, which typically include warm, sunny weather and poor water circulation. Of course, this combination is often found in Central Florida pools, making them prone to algae infestations.

The most likely sources of algae are the environment itself and items or individuals that come into contact with the pool. Algae spores can be carried by the wind, rain, or even birds, and then deposited into the pool water. They can also hitch a ride on swimwear, toys, or pool cleaning tools that have been in contact with infested water.

Identifying the Problem

Understanding what encourages algae growth is essential for prevention and treatment. Key contributors include:

  1. Poor Water Circulation Stagnant water provides the perfect conditions for algae to grow. Efficient circulation ensures pool chemicals are evenly distributed, deterring algae bloom.

  2. Insufficient Sanitizer Levels A pool without enough chlorine or other sanitizers is a breeding ground for algae. These sanitizers are crucial in killing algae spores before they can multiply.

  3. Unbalanced Water Chemistry Besides sanitizer levels, other chemical imbalances like pH, total alkalinity, and calcium hardness levels can also create a friendly environment for algae.

Banishing the Green Menace

Here's the good news: You can get rid of algae with a little bit of effort and the right tools.

  1. Scrubbing and Vacuuming A manual clean-up is the first step. Scrub the walls, floor, and any other infested parts of the pool using a pool brush. This will dislodge algae colonies, making them easier to eliminate. Vacuum the pool to remove the scrubbed-off algae.

  2. Shock Treatment 'Shocking' your pool involves adding a large dose of chlorine (10-12 ppm) to kill off the algae. After shocking, run your filter system continuously until the water clears up.

  3. Algaecide Application An algaecide can help kill any remaining algae and prevent new spores from growing. Choose a quality product that specifically targets the type of algae you have.

Preventing Future Infestations

Maintaining a clean, algae-free pool is a continuous process. Here are a few steps to help prevent future algae blooms:

  1. Maintain Proper Circulation Regularly run your pool pump and use pool brushes or an automatic pool cleaner to prevent stagnant water that promotes algae growth.

  2. Keep Your Pool Properly Sanitized Regularly test and adjust the sanitizer levels in your pool. The recommended chlorine level is between 1.0 and 3.0 parts per million.

  3. Balance Your Pool Chemistry Regularly check and adjust your pool’s pH, total alkalinity, and calcium hardness levels. The ideal pH for a pool is between 7.4 and 7.6.

  4. Regular Shock Treatment Even in a well-maintained pool, it’s good practice to shock your pool every 1-2 weeks during the warm season.

  5. Use Algaecide Regularly Especially during the warmer months, using a preventative algaecide can help keep algae at bay.

  6. Clean Pool Equipment and Accessories Regularly clean pool tools, toys, and even bathing suits that come in contact with your pool to avoid introducing new algae spores.
