How to prevent algae growth in my cold plunge tub?

To prevent algae growth in your cold plunge tub, maintain proper sanitation and circulation of the water. Regularly checking and balancing pH levels and using appropriate algaecide can be effective. Algae typically thrive in warm, stagnant water, so ensuring your tub is used frequently and cleaned regularly makes a big difference. For instance, if you notice greenish tinting, it’s time to clean and treat the water. PRO TIP: Consider adding a small pool cover when the tub is not in use to reduce exposure to sunlight. CONSIDERATION: If you frequently host gatherings, be prepared to increase your cleaning frequency to combat algae.
