Tips for Getting Rid of Yellow Algae Once and For All
Any type of algae infestation in a swimming pool can be a challenge for a pool owner, but yellow algae is even more complicated than the standard green variety. Yellow algae, also dubbed mustard algae due to its yellowish brown hue, is much more stubborn than its green counterpart. While this algae will respond to the standard algae treatment, it might not be enough to get rid of this infestation once and for all. You need to bring out the heavy guns and show plenty of perseverance if you want to truly rid your pool of yellow algae
What is Yellow Algae?
Algae are living creatures that multiply quite efficiently when conditions are optimal. These conditions include warmer temperatures, lots of sunshine and an imbalance in pool water that leaves chlorine levels lacking. Yellow algae most frequently shows up on the shady side of the pool and it can be resistant to the typical chlorine levels. Yellow algae cause major headaches for a pool owner. Algae can clog filters and use up chlorine that is needed to keep other contaminants at bay. It is important to hit yellow algae as hard as you can and as fast as you can to ensure it goes away completely and doesn't return.
A shock treatment is the first step in eliminating yellow algae. Some experts recommend shocking the pool with as much as triple the amount usually used. Every algae also requires treatment with an appropriate algaecide. However, the best choice for green algae is not going to work as well for the more stubborn yellow variety. You need to use an algaecide specifically designed for yellow algae, such as one with sodium bromide in the mix. Sodium bromide combines with a shock treatment to create bromine, a substance that has been proven quite effective in dealing with yellow algae. As the treatments work, brush the sides of the pool to ensure the algae spores come in contact with the chemicals.
During the chemical treatments, raise your chlorine levels to as high as 10 PPM and then let it sit overnight at anywhere from 1-3 PPM. It is also important to keep the filter running at all times during the treatment. Allow the pool to continue to circulate for 24-48 hours to ensure the problem gets addressed completely. By the end of the treatment, there is typically grayish white sediment that settles on the pool floor. Pools with cartridge filters need to be cleaned out daily or every other day while the sediment is being removed. If your pool has another type of filter, make sure you vacuum the pool thoroughly before using.
Once the yellow algae is gone, make sure to follow a strict maintenance schedule and test and balance your water regularly to make sure the algae doesn't return. If you see any signs, repeat treatment right away. By hitting yellow algae fast and hard, and keeping close watch that it doesn't return, you can successfully eliminate yellow algae for the entire swimming season.
