The Algae Menace

Green Gunk: Types of Algae You May Encounter

There are mainly three types of algae that can infest your pool:

  1. Green algae: The most common variety, it thrives in warm water and sunshine and clings to pool surfaces.
  2. Black algae: The most stubborn kind, it forms strong roots within the cracks of your pool surface and is highly resistant to pool chemicals.
  3. Yellow algae: Also known as mustard algae, this type prefers the shady areas of your pool and is chlorine-resistant.

The Root Causes of Algae

  • Insufficient circulation: Stagnant water results in less effective filtration, providing ideal conditions for algae growth.
  • Unbalanced water chemistry: Improper pH levels and insufficient sanitizer levels can both lead to an algae-friendly environment.
  • Environmental factors: Debris such as leaves, dust, and pollen can introduce algae spores to your pool.

Pool Maintenance: Combating Algae

Effective Ways to Remove Algae

  1. Balance the pool chemistry: Ensure that the pH, total alkalinity, and chlorine levels are within the ideal ranges.
  2. Shock treatment: Adding a large dose of pool shock to your water will kill off the algae.
  3. Brushing and vacuuming: Regularly brushing the pool surfaces and vacuuming the debris will help prevent the growth of algae.
  4. Utilize algaecide: A preventative approach using an algaecide will help keep algae at bay.

Tips for Algae-Free Pool Filters

  • Clean out your skimmer baskets regularly.
  • Operate your pool pump for at least 8-10 hours a day.
  • Ensure the pool filter is clean and functioning correctly.

The Backwash Schedule

Understanding When to Backwash

  • When the filter’s pressure gauge reads 8-10 PSI higher than the normal operating pressure.
  • After a heavy rainstorm or extreme weather event.
  • Following a pool party or a period of heavy pool usage.

Backwashing Techniques

  1. Turn off your pool pump.
  2. Set the backwash valve to the right position.
  3. Turn the pool pump back on and let it run for about two minutes.
  4. Turn off the pump and return the valve to its normal position.
  5. Restart the pump and check the pressure gauge.

What You Need to Know About Backwashing with Algae

When dealing with an algae infestation, it’s crucial to follow a strict backwashing schedule. Ensure that you backwash after each algae treatment, as dead algae spores can clog your pool filter, reducing its efficiency. If you’re dealing with a persistent algae problem, consider backwashing more frequently than usual.
