Ways To Keep Algae Out Of Your Water Tank

Water is required for life on Earth to exist. Around 2.1 billion people worldwide live without access to safe, clean, and reliable drinking water. According to a statement released by UNICEF and the World Health Organization, nearly 4.5 billion people do not bear access to adequate sanitation. Proper water storage is crucial for maintaining a safe and clean supply. You are not alone in your desire to extend the life of your tanks.

Proper Water Storage

Proper water tank storage and lining are vital to the environment. Algae growth is one factor that may affect your ability to extend the life of your tanks. If any of these contaminants are identified in your drinking water, it becomes unsafe to consume for humans, animals, or plants. Algae are known to host pathogenic bacteria that are fatal to various organisms.

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

Before calling in services for bulk water delivery, there are steps you can do to prevent the growth of harmful algae and bacteria in your water tanks. Here are some ideas for increasing the life of your tank and avoiding algae growth.

Opaque Tanks

Always purchase entirely opaque tanks. Algae use sunlight to obtain energy and grow. This is because the organism is photosynthesis-dependent. Algae cannot survive without sunlight. Additionally, algae are less likely to colonize if your tanks receive no sunlight. As a result, algae are less likely to collect in your tank, and those that do will die.


Bleach should be used to disinfect the area and kill the algae. If you have an algae problem, you can eliminate it with bleach. A quarter teaspoon per gallon of water in your tank should be the ratio. Bleach is extremely effective in eradicating algae (and other creatures that may be lurking in your tanks) and preventing its recurrence. According to scientific studies, bleach made from a solution containing 5.25 percent hypochlorite is effective. Combining bleach and chlorine is never a good idea. This combination is also referred to as chlorine gas, which nobody wants.


Utilize chlorine. Chlorine is highly effective at inhibiting the growth of algae. To 1,000 parts water, add four parts chlorine. When the amount of chlorine used is not excessive, the water remains potable and does not taste foul.


It is vital to monitor the bleach-to-water and chlorine-to-water ratios. This will eliminate or significantly limit algae growth while also keeping the water clean. You can simply keep algae from developing in your tanks, cisterns, and reservoirs by employing these strategies. There is no use in collecting rainwater if it is allowed to grow algae. Even using a robust water treatment tank lining will not assist if algae have invaded your tanks.

To Conclude

You should do this sanitization process on your tanks every six months to a year to help prevent contaminants and algae from forming in the first place. Due to the rarity of algae growing in freshwater tanks, provided you adhere to a regular sanitation plan. If you follow the directions above to the letter, you should have an algae-free freshwater tank.
