Algae
If there are slimy coating inside the hot tub spa, then most likely that your hot tub is under algae attack. Please note that algae may not appear green at all times. Sometimes it has black or mustard color.
Algae starts to thrive in your hot tub if the water’s pH level is imbalanced. Moreover, algae spread fast if the hot tub cover is removed since they need sunlight to thrive.
High metal content
Tap water is consist of different metal contents, and one of which is copper or iron. And whenever you shock the water, there is a possibility that the oxidation of chemicals causes the copper content of the water to react, thus giving the greenish look of the water.
Not Enough Sanitizer
Aside from imbalanced water, low sanitizer also causes green hot tub water.
How?
Without enough sanitizer in the water, bacteria and germs will thrive in the water. This also makes a great environment for algae to grow. Sanitizers destroy the microorganisms present in the water.
Dirty Filtration System
A hot tub with an excellent filtration system pumps hot tub water through a microfilter. What this microfilter does is to trap all contaminants so that they can be easily removed from the hot tub water.
Now, imagine if the system that supposedly cleanse the water has become a place where microorganisms thrive, breed, and multiply? Gross!
