When it comes to your outdoor space, you have unique swimming pool preferences based on several factors: the size and shape of your backyard, your family’s swimming pool use, your budget, and your desired aesthetic. But no matter what your exact set of circumstances, we’re willing to bet that one thing you don’t want to include is an algae infestation!
In our past 2 posts in this series (see Part 1 & 2), we learned about the basic ways that algae growth is encouraged as well as how to avoid it. We also looked at specific details about the first 2 types of algae: black algae and green algae. Though less common than the other 2, mustard algae may be the least recognized and is the most stubborn form of algae; that one will be our focus for today.
Mustard Algae Basics
This particularly chlorine-resistant algae type is actually a form of green algae. Mustard algae is tricky to spot, because it can look very similar to sand or dirt as it forms on the sides or bottom of a swimming pool. Because it contains compounds that resist the oxidation promoted by chlorine and other sanitizing chemicals, it can be especially stubborn and difficult to eliminate once it begins to grow. Of course, the longer it grows unnoticed, the more of a stronghold it attains, making it even more difficult to eliminate. Getting rid of mustard algae can be even more challenging when it grows in your pool’s filter and then attaches itself to bathing suits and other items that enter and re-enter the pool. As a result, you’ll need to potentially treat repeatedly not only your swimming pool but also any items that have been in your pool and that you plan to use in your pool.
Mustard Algae Treatment
Able to survive in highly chlorinated water, mustard algae can be difficult to treat. It can be easily brushed away, but then it can just as easily return. As with the other types of algae, the first step to treating mustard algae is to test your water and make sure chemical levels are balanced. Next, you’ll want to shock the pool using a quality product and forcefully brush any affected areas. After you’ve done that, you need to remove any dead algae by vacuuming or backwashing. Then apply a mustard algaecide and leave the pool filter running for a 24-hour period of time. After running the filter, again backwash or vacuum in order to remove any dead algae that remains.
If your mustard algae seems to be especially resistant to any efforts of removal, you may need to brush surfaces again and then apply products after 2 or 3 days. Once you have completed this remediation process, be sure to again test and balance the chemical levels of your pool.
Any algae in your swimming pool – black, green, or mustard algae – will be an unwanted addition to your outdoor oasis. You can reduce the likelihood of having algae enter your pool to begin with by being extremely cautious about allowing anything to enter your pool that has been in a natural body of water previously. If you do allow items to be used in your pool that have also been used in a lake, creek, or ocean, be sure to thoroughly sanitize those items before allowing them into your pool.
