What are some signs that my pool water is unhealthy?
Cloudy water. This is caused by blooms of algae that result from a lack of sanitiser in the water.
When algae growth is out of control, pool water will turn green or dark brown, depending on the type of algae. You’ll see this first in places where the water circulation is poor, such as corners, steps and where the pool floor meets the walls.
Yes. It can cause a range of health issues, including eye and ear infections, itchy skin and intestinal infections. However, it is important to note that you can have crystal clear water that is unhygienic too.
What should I do if my pool goes cloudy?
First, take a water sample from elbow depth to your pool specialist so they can recommend the correct chemicals and the right dosages to treat the algae.
Treating a pool with an algae bloom is fairly straightforward – add acid, chlorine and a flocking agent (with the amounts recommended by your pool specialist), then vacuum.
If the water is contaminated and requires bleaching, seek advice from your pool specialist. This is important because you’ll be handling dangerous chemicals and you need to understand how to use them safely – in particular, what not to do, such as pouring chemicals in the wrong order or putting acid in a container that once stored chlorine.
My pool water is dark green – should I just empty it out?
Don’t! No matter how bad it looks, never empty the water from your pool as it can create a number of financial and structural problems. This is because water acts as a stabiliser that weighs the pool down when it’s in the ground. When you take that water out, it can ‘pop’ out of the ground or the walls can cave in.
