Is your pool trying to tell you something?
If your pool could speak, green water would be a desperate cry for help. That alien hue literally means your pool has dead spots and it is being invaded by another life form – algae. Just as poor circulation leaves our bodies vulnerable to illness, poor circulation compromises your pool’s health.
While your pool’s pump is like a heart, and very efficient at drawing water from the surface of the pool into the filter where it can be cleaned and sanitised, it can’t circulate water from the middle and bottom layers of your pool. The right cleaner however, can.
Circulation beats agitation
Suction cleaners work in tandem with the pump to draw water from the bottom of the pool and send it through the pool filter and sanitiser to kill nasty bacteria. Not only is water cleaned, then thoroughly circulated, this motion also ensures chlorine or salt is fully dispersed around the pool.
And this happens every day, every time the pool pump runs. The result? Crystal clear water and a healthy, sparkling pool.
Unfortunately it is a different story with cleaners that work independently of the pump. While they blow water around the bottom of the pool, and the return jets disperse water on the top, the middle layer of the pool can literally be left unmoved. This is the dead zone that leads to green spots. The fact that these types of cleaners aren’t leave-in-the-pool cleaners compounds the problem – the water isn’t being circulated effectively or often enough.
Leaf no trace
Another cause of pool discoloration is staining on the bottom of the pool, caused by tannins leeching from leaves, nuts and berries. Prevention is better than cure, so giving the pool a daily clean will remove the organic matter before it has a time to break down. Again, suction cleaners have the advantage over robotics on this score.
