If you notice a brown or yellow algae settling on your pool walls or floor, it’s once again time to reach for the scrub brush. Regular cleansers often have a hard time reaching mustard algae because it tends to collect at low water levels. Fortunately, this strain of algae is far less stubborn than black algae. Good scrubbing, vacuuming, and water balancing should clear it up.
It is important to note that re-infection is very common with mustard algae. This algae can survive on pool toys like floaties or noodles, and it can even escape treatment by hiding in the pool filter. It can also live within your trusty scrub brush, undoing all your hard work! Inspect and clean all your pool supplies and accessories when you notice mustard algae.
Blue or green algae is the most common strain of pool algae, but it is no less difficult to clean. Green algae clings to the walls of your pool, but can also be free floating which creates murky, swamp-like film over the water. You guessed it – you’ll need the good ole’ scrub brush and some borax.
In the same way that baking soda can be a spot treatment for black algae, household borax does the same for blue and green algae. Simply use the borax to scrub away algae that’s sticking to your pool walls, then use the brush to dislodge it. Follow up by vacuuming up or scooping out the free-floating algae. You will have a much easier time once the borax has stopped the algae from blooming.
Eliminate Algae of All Types
The goal is to never have algae. Test your water regularly, keep your filter clean and in good working order, and be sure to treat your water after big pool parties. Using a floating pool skimmer and chemical dispenser like the Solar-Breeze NX2 will remove debris from the surface of your pool before it has a chance to sink, decay, and turn into food for algae. With careful pool maintenance, algae can be one thing you do not have to worry about.
