What Causes Yellow Algae

Mustard algae can be really annoying to deal with. The spores enter your pool either through your pool equipment and bathing suit contaminated with the algae spores or elements, such as rain or wind.

The speed of the algae bloom will depend on your location and specific situation. The factors that affect how quickly it blooms are the following:

  • Plenty of sunny days or if you live in a place with a mostly warm climate
  • If your pool has high levels of carbon dioxide or nitrates
  • Improper filtering, maintenance, and sanitizing of your pool
  • Pool chemicals are not balanced
  • Overlooking pool circulation

The lack of chlorine and proper filtration are the two main culprits of yellow algae. Many factors play a part in these, including sanitation techniques, run time, bather load, pump speed, and weather. For example, if you live in Florida, your pool water will not be kept clear with a pump run time for six hours during August. The ideal run time you want to start with is at least 8 hours.

    What Causes Algae To Form In A Pool

    The main cause of algae in a swimming pool is low free chlorine level. Algae is rampant in hot and humid climates or during the summer, simply because chlorine reduces faster as water temperature increases leaving your pool vulnerable to algae and bacteria.

    As such, the only way to keep algae and bacteria away is to maintain recommended FC level of 3ppm all the time by adding chlorine whenever it drops below 3ppm and this should be done on a daily basis. But don’t think, even for a moment, that maintaining chlorine levels is enough: You need to maintain an appropriate balance of all chemicals in your pool because they affect how long chlorine lasts in your water.

    Most chemicals used in the pool, such as pH chemicals, sanitizers, alkali, calcium, stabilizers, and more, will affect how chlorine works and how it is consumed. For this reason, the only perfect way to avoid algae or cloudy water is to constantly maintain the correct chemical balance in your water, which means using an accurate pool water testing kit.

    Causes For Pool Algae Development

    Anyone who decides to build a pool in their back yard should learn how it is properly maintained.

    If you dont do that, instead of a place to relax in, it will become just another chore around the house.

    With the right care your pool will always stay fresh and clean.

    Proper maintenance means you need to thoroughly clean the pool on a regular basis and use the appropriate care products.

    If you neglect this for long enough, dont be surprised if the water turns cloudy or green.

    The pH value and the colour of the water provide information on the water quality and indicate which cleaning measures are necessary.

    Ideally, the pH value is 7.4. A pH value higher than 7.4 is really good for algae. Algae and bacteria are not always responsible for discoloured water or deposits on the walls:

    • Yellow-green water: indicates the increased iron concentration
    • Cloudy water: indicates pollution from organic residues
    • Slippery walls: algae or bacterial covers
    • Rough pool walls: means calcification of the water

    If there isnt enough algae protection in the pool water, the risk of algae growth increases. The pH value has a significant influence on algae growth. The organisms need nutrients to grow, which they get from leaves, hair, cosmetics or skin cells.

    If You Already Have An Algae Problem

    If you have green algae already, then the first thing youll want to do is shock it until the pool is a blue/grey shade. Be sure to remove any pool cleaners or solar blankets so they arent affected by the high chlorine level. You must use enough chlorine when trying to kill algae, pouring it directly in affected areas, or if you have algae all over the pool, then distribute evenly. Dont forget to lower the pH first to between 7.2 – 7.4 so the chlorine is as active as possible.

    After the shock, brush the whole pool thoroughly and take special care to get into all the little nooks and crannies of your pool such as behind the ladder or around the drains. Also consider areas that could have had algae exposure such as the underside of the pool cover.

    After a chlorine shock and a good clean, youll need to pay particular attention to regrowth. PH levels much be correct, so check these daily. Also clean filters that might have removed algae from the pool.

    Washing all swimsuits on a very hot cycle with bleach is advisable and bleach all of your nets, vacuum heads, accessories and cleaning equipment.

    If you have a sand filter, you should also replace this.
