Algae Control in Spas & Hot Tubs

Algae can be a problem for any sanitation system, it grows very quickly once it gets a hold and colours the water green.

The potential for algae bloom can be removed from a spa by removing the algae’s primary food source - phosphates. Without its main nutrient the potential for algae growth is significantly reduced. 

Where do phosphates come from?

Unfortunately phosphates can be present in the tap water in quite high quantities in some areas of the UK because the water authorities add them to reduce the amount of lead leaching into the water from old pipe work.  Phosphates also come from leaves falling into your tub and bather wastes such as sweat and urine. Other phosphates sources are detergents, some insecticides, fertilisers, soft drinks, toothpaste and even some pool and spa chemicals.

How do I remove algae from my tub?

If algae does ever get a hold in your hot tub then the best solution is to first remove the the food, using a phosphate remover, and then to shock the water with a sodium based shock treatment, such as SpaLite, to kill the algae.  You should then thoroughly clean your filters using a proprietary filter cleaner, such as FilterBrite, and immediately re-apply your chosen sanitize. 

Assuming that the correct santiser level is maintained, the problem shouldn't reoccur until the next time you change your water.

Note: As an alternative to using SpaLite, you could also kill the algae by super-chlorinating the water to 20 ppm of free chlorine, but you must wait for the chlorine level to reduce to a safe level before bathing again.
