Pool Algae Removal in Phoenix
Green spots on the walls, yellow dust in the corners, or black dots that won't brush off? We identify the algae and treat it properly.
Not All Algae Is the Same
Green algae is the most common. It floats in the water and clings to walls, turning the pool cloudy or green. It responds well to proper shocking and filtration.
Yellow or mustard algae looks like dust or pollen sitting in shady corners and steps. It brushes away easily but comes right back if it isn't treated thoroughly. Black algae shows up as dark spots with roots in the plaster, and it takes aggressive brushing and repeated treatment to get rid of.
Identifying which type you have matters, because the treatment and the number of visits are different for each.
How We Remove Pool Algae
We start by testing and balancing the water, since chlorine works poorly when pH is off. Then we brush the affected areas hard to break up the algae's protective layer, shock the pool, and run the filtration. For stubborn types like mustard and black algae, we treat spots directly and repeat brushing and shocking over follow-up visits.
Dead algae ends up in the filter, so we clean or backwash it during the process. Pool toys, floats and cleaning tools can carry algae back in, so we'll let you know what should be cleaned too.
Why Algae Is Common in Phoenix Pools
Algae thrives in warm water, and Phoenix pools stay warm for most of the year. Intense sun burns through chlorine, while monsoon dust and debris add nutrients that algae feeds on. Shaded corners, steps and areas with weak circulation are usually where it shows up first.
High cyanuric acid (stabilizer) is another common local issue. Stabilizer protects chlorine from the sun, but too much of it makes chlorine less effective, which can let algae grow even when chlorine readings look okay.
Algae Removal vs. Green Pool Cleanup
If the whole pool is green and you can't see the bottom, our green pool cleanup service covers the full recovery. Algae removal is the right fit when the water is mostly clear but algae keeps showing up on walls, steps or corners. Either way, we'll tell you which one makes sense when we see the pool.

Frequently Asked Questions
Why does algae keep coming back in my pool?
Usually because of low chlorine, high stabilizer, poor circulation, or a dirty filter. Fixing the cause is just as important as killing the algae.
Can black algae be removed completely?
It can be controlled and removed with aggressive brushing and repeated treatment. Older plaster with deep roots may need more visits.
Do I need to drain the pool to get rid of algae?
Usually not. Draining is only recommended when the water itself has problems, like very high stabilizer, that keep chlorine from working.
