Tips for Preventing and Removing Algae

Algae has its place in ecosystems and can be very beneficial. However, it can wreak havoc on your pool. If you find that your pool is suddenly green, yellow, or see black spots on the sides and bottom of the pool, you have an algae issue. Not only does it make your pool an unattractive color, but it can damage your pool and allow dangerous microorganisms to thrive. It's critical to nip an algae problem in the bud before it becomes unmanageable. Let's take a look at tips for preventing and removing algae from your pool.

What Type of Algae are You Dealing With?

It's important to be able to spot algae as soon as it starts. There are three main types to be on the lookout for. Green algae is easy to identify and the most common. Your water will turn a greenish color, and you may see algae floating on top of the water. The second most common type is yellow algae. It is harder to identify because it looks very similar to dirt and sand and most commonly grows at the bottom of your pool. The third kind is rare but very difficult to remove and the most damaging to your pool. It is black algae and looks like black spots on the sides and bottom of the pool. It causes the most damage because the roots can grow through your pool's liner and surface.

Knowing what to look for will you help you identify algae immediately before damage can occur.

Algae Prevention

Of course, the prevention of algae is preferred. Follow these tips to help keep algae out of your pool:

  • Ensure phosphate levels are below 100 ppb
  • Shock your pool weekly (or more often if needed)
  • Brush the sides and bottom of your pool at least once a week (more often if needed)
  • Make sure your filter pump is set to run at least once an hour

Algae Removal

Ideally, your preventative strategy will ward off any algae growth. Unfortunately, even with the best plans, nature can concoct the perfect environment for algae growth in your pool. Here's what you need to know about algae removal.

  • First, identify what type of algae you are dealing with
  • Thoroughly clean your pool's filter (run your pump for at least 36 hours during treatment)
  • Increase the water's pH to at least 7.8
  • Ensure the total alkalinity is between 80-120 ppm
  • The cyanuric acid level should be between 30 and 75 ppm
  • Free available chlorine needs to be at about 2.5 pp

Once your pool's water meets the above criteria, you can begin with the removal process:

  • Rigorously brush the sides, bottom, and steps of the pool. Either leave the brush in the pool during treatment or disinfect separately.
  • Purchase the correct algaecide and carefully follow the manufacturer's directions for treatment.
  • Shock your pool with calcium hypochlorite - once again, be sure to follow label instructions.
  • Wait about 12 hours and then turn off the pump.
  • Test the water and ensure phosphate levels are below 100ppb. If not, use a phosphate reducer (algae feeds on phosphate).
  • Clean your filter once again.
  • Remove dead algae with a removal product.

Be sure to conduct a final water test to ensure levels are where they need to be. Once your pool is back to health, you and your family and go back to enjoying it again!
