It always seems as though algae blooms in our pools at the worst times – when the weather’s warm, and everyone starts swimming. Although this is possibly the worst time to get algae, it’s actually the most expected time to get it. The primary cause of algae is low levels of chlorine in your water. Chlorine levels plummet every time the sun beats down on the water and when there’re plenty of bathers in the water. That being said, make sure you’re putting extra chlorine in your water during these times.
Sometimes, our pool chemistry falls out of place and our water gets a little dirty. So, here’s a guide on how to spot algae in your swimming pool:
Green Algae
This type of algae grows on the walls of pools, sometimes turning the water completely green. This algae is fairly easy to spot because of its bright colour. When you see it, be sure to act as quickly as possible to get the right chemicals in your water.
Mustard Algae
Mustard algae disguises itself as sand. So, if you see a sand-like substance at the bottom of your pool, it’s probably algae. One way to tell the difference between sand and mustard algae is algae is light and will puff away when brushed, whereas sand will simply displace. Mustard algae is easy to brush off walls and floors, but will resettle fairly quickly.
Unfortunately, this algae is difficult to get rid of, so expect to put in a bit of work to get it out. With the right chemicals, however, you can get it out of your pool once and for all.
Black Algae
This algae appears as bluish-green spots around the pool. The spots usually form in dead space where circulation is low. Black algae is another difficult algae to get rid of. Brushing it off the walls is a strenuous task as it adheres strongly to the sides of pools. Also, black algae can survive in some of the harshest conditions so if the algae isn’t completely gone by the end of the season, expect to see it again the following spring.
Pink Algae
This is a fairly common form of algae that presents itself as slime. It tends to grow on walls and around lights. Compared to other forms, pink algae is not difficult to treat. With the right chemicals, you can get rid of this algae pretty quickly.
