Green Pool Solutions

Are you tired of dealing with green, murky pool water every swimming season? Algae growth is a persistent problem that many pool owners face, but it’s not impossible to overcome. In this article, we’ll explore some practical solutions on how to fix and prevent algae growth in your pool.

What is Algae, and How Does it Form in Your Pool?

Algae are microscopic plant organisms that thrive in warm, moist environments. They enter your pool through various means, such as wind, rain, and contaminated swimming gear. Algae spores quickly multiply in your pool if the conditions are suitable, forming those unsightly green or yellowish patches.

The most common types of algae species found in pools are green algae, yellow or mustard algae, and black algae. Green algae are the most frequent offender, causing the infamous green water and slime buildup on pool surfaces.

Albarda (2023) pool algae can be caused by poor filtration, out-of-balance water, low or inconsistent chlorine levels, or poor water circulation.

Additionally, In the Swim (n.d.) informs us that:

algae spores can also blow into the pool, or can even be introduced by contaminated ocean swimwear. In short, algae are always in the pool, and can bloom into a visible colony when conditions are right:

  • Poor water circulation; low flow or dead spots in the pool
  • Poor water balance; pH, Alkalinity, Calcium and Cyanuric levels
  • Poor water sanitation; low or inconsistent chlorine levels
  • Poor water filtration; short filter run times or an ineffective filter.

How to Fix a Green Pool

When you notice your pool water turning green, the first step is to determine the extent of the problem. In cases of a minor algae bloom, employ the following steps to fix it:

Brush the Pool Walls and Floor
Use a pool brush. Vigorously scrub off any visible algae growth from the pool surfaces. This action dislodges the algae and exposes them for the next step.

Shock the Pool Water
Shocking the pool refers to raising the chlorine levels of your pool beyond normal levels. This process helps kill off the remaining algae spores in the pool. Follow the instructions on your pool shock product for the right dosage and timings. Keep your pool pump working throughout the shock process to promote adequate circulation and filtration. Read one of our other articles titled, “How Often to Shock Your Pool.”

Vacuum the Pool
After the shock process, vacuum the entire pool, disposing of all debris and dead algae into the filter. Apply a pool clarifier if you notice excessive cloudy water or debris.

Retest and Balance Pool Chemicals
Once the shock treatment completes, wait for 24-48 hours before checking the pool water levels. Adjust the chemicals accordingly, ensuring that the proper pH, alkalinity, and chlorine levels are met.

The best way to maintain a clear, clean pool is by outsourcing pool cleanings. You won’t have to stress if you turn pool cleanings over to us.

How to Prevent Algae Growth in Your Pool

Prevention is always better than cure, so it’s essential to implement measures that help prevent algae growth in your pool:

Regular Pool Maintenance
Schedule regular pool maintenance with a reputable pool cleaning service. This service includes brushing, skimming, and vacuuming your pool, testing pool chemicals, and maintaining equipment like pool filter, pump, and heater.

Balance Your Pool Chemicals
Maintain proper pH levels between 7.2-7.8 and optimal chlorine levels for killing off bacteria and algae growth. Ensure that alkalinity levels are also balanced.

Keep Your Pool Clean and Free of Debris
Leaves, twigs, and other organic matter provide a breeding ground for algae to flourish. Skim the pool surface daily to remove any debris. Use a pool cover when not in use.

Proper Filtration and Circulation
Ensure the filter is correctly installed and maintained to provide adequate circulation and filtration. Run your pool pump for at least 8-12 hours per day to promote proper water flow. We offer a Pool Filter Cleaning Service.
