How to Keep Your Water Tank Algae-Free

Water is a necessity for life to exist on Earth. Around 2.1 billion people worldwide lack access to safe, clean, and dependable drinking water in their homes. According to a UNICEF and World Health Organization report, almost 4.5 billion people do not have access to safe sanitation. Proper water storage is essential for keeping it clean and safe. You’re not alone if you want to extend the life of your tanks.

Proper Water Storage

Proper water tank storage and water storage tank liners are vital for the environment. Algae growth is one issue that may limit your ability to extend the life of your tanks. If any contaminants are identified in your water, it is no longer safe to drink for humans, animals, or plants. Pathogenic bacteria found in algae can be fatal to a variety of species.

What can you do to keep your water tank algae-free? 

Before calling in services for water delivery for cisterns and tanks, you can take steps to keep harmful algae and bacteria from growing in your water tanks. Here are some pointers for extending tank life and reducing algae growth.

Opaque Tanks

Always get opaque tanks. Sunlight is essential for algae to gather energy and grow. This is owing to the organism’s dependency on photosynthesis. Algae cannot grow in the absence of sunlight. Furthermore, if your tanks do not see any sunlight, algae are less likely to build a new home. As a result, algae are less likely to collect in your tank, and if they do, they will die.


Bleach can be used to kill the algae. If you have an algae problem, you can use bleach to eliminate it. The ratio should be a quarter teaspoon per gallon of water in your tank. Bleach is fantastic for removing algae (and other organisms that may be lurking in your tanks) and preventing its regrowth. According to scientific evidence, using bleach made from a solution containing 5.25 percent hypochlorite is effective. Never combine bleach with chlorine. This combination is also known as chlorine gas, which no one wants.


Make use of chlorine. Chlorine is good at inhibiting algae growth and is used by many water suppliers like Bright Water Services. To 1,000 parts water, mix four parts chlorine. When not too much chlorine is used, the water remains potable and does not taste bad.


It is vital to monitor the bleach-to-water and chlorine-to-water ratios. This will destroy or slow the formation of algae while also keeping the water clean. Using these methods, you can simply keep algae at bay in your tank. It’s pointless to gather rainwater if algae grows on it. Even using a solid and powerful water treatment tank lining will not help if algae have colonized your tanks.


You should go through this sanitization procedure with your tanks every six months to a year to help prevent contaminants and algae from forming in the first place. Because algae are unlikely to form in freshwater tanks, keeping them clean should be straightforward if you follow a regular sanitation routine. If you follow the directions in the letter, you should have an algae-free freshwater tank.
