Algae is not welcome in your spa or hot tub!
Algae can take various forms and colours from green, yellow, pink, white and even black. They can cause your water to take on a green tinge, become cloudy or feel slimy. If left for a prolonged period of time, they can form green or black slime.
The first indication of an algae bloom will be a significant increase in sanitiser use. You’ll find that you’ll be adding more and more sanitiser and still struggling to keep your water clear.
Algae are not bad characters in small doses however some can be toxic and no one really likes to share their spa with algae, which at the least, significantly reduces water clarity.
In this article, we'll discuss how to prevent algae and how to treat it if it rears it's ugly head in your spa!
If your water has been green for less than 24 hours then you may be able to bring it back around again. Follow the steps below;
If these steps don't work and your spa water still has a green tinge, you can try these more involved techniques below;
Spa shock can be used to help reduce algae however the effects are very short-lived, as these products are not true algaecides. Make sure you remove spa pillows, headrests and your cover before using spa shock.
Poppit Pool & Spa Complete Maintenance followed by frequent cleaning of your spa filter cartridges with Poppit (phosphate-free) Filter Cartridge Cleaner will not only remove the problem, but it is also extremely effective prevention.
Poppits® 3 month algaecide is considered to be the strongest. This is the only algaecide compatible with chlorine-free (Hydrogen Peroxide) sanitiser.
Follow instructions on the label of the algaecide. 30 mL / 1,000 litres is generally sufficient to kill the algae and will clean up the spa within 48 -72 hours. This will provide protection for the life of the water in the spa.
NOTE: (Phosphate removers do not actually remove phosphates from your spa. Instead, they form an insoluble molecule that becomes trapped in the filter. This means it is important to regularly clean your spa filters, especially after using an algaecide
Make sure to soak and clean your filter after using these algaecide and phosphate-removing products.
We recommend the Poppit spa filter cleaning solution because it is the only filter cartridge cleaner that can make the claim that it is free of phosphate, sulfate or nitrate. All of which act as Hors d’oeuvres at the algae party.
If an algaecide is not completely effective within 72 hours and there are still signs of algae, you will need to empty your spa water and replace it with fresh water. You'll need to re-balance and sanitise your spa. Follow the directions in the water quick start up guide if you need help.
Ensure you are replacing your filter cartridges regularly. We recommend replacing your filters every 11-12 months for a standard spa with normal use and every 12-18 months for a swim spa. Spas with higher usage may require the filters to be replaced more regularly.
Green water in your spa is most likely caused by algae growth that has been able to thrive because of insufficient sanitiser. This could mean your water is not safe to enter as there will likely be bacteria and other microorganisms that have been able to multiply in your spa water.
Some forms of algae are harmful to your health. Algae in your spa water is also a sign that something is not right with your water balance. Algae will form when your sanitiser is not working properly, which can mean that other invisible bacteria may have formed in your spa water.
Algae is a tiny plant-like microorganism that grows in water. Like all organisms, it needs food to grow. The main source of food for algae is phosphate - which is a naturally occurring inorganic chemical that is widely used in detergents, animal feed and fertilizers.
Many common household laundry detergents, soaps, shampoos and beauty products contain phosphates. When you and your guests use your spa, small amounts of residual phosphates will remain in your spa water - leaving food for algae!
Other contributing factors to algae growth include;
