How To Avoid Algae Growth In Your Water Tank

On Earth, life is impossible without water. Around 2.1 billion people globally lack access to safe, clean, and reliable drinking water at home. Nearly 4.5 billion people live in areas without access to safe sanitation. According to a report released by UNICEF and the World Health Organization, this is the case. Proper water storage is crucial for maintaining a safe and clean water supply. You are not alone in your desire to prolong the life of your tanks.

Proper Water Storage

Proper water tank storage and lining are crucial for the environment. Algae growth is one concern that could compromise your ability to extend the life of your tanks. When any contaminants are identified in your water, it becomes unsafe to drink for humans, animals, or plants. Algae are a reservoir for pathogenic bacteria that can be fatal to various organisms.

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

Before calling your “refill water tankcompany, there are steps you can do to keep your water tanks free of toxic algae and bacteria. Here are some helpful suggestions for extending the life of your aquarium and avoiding algae growth.

Opaque Tanks

Ensure that all tanks are opaque. To gain energy and grow, algae require sunlight. This is because the organism is photosynthesis-dependent. Without sunlight, algae cannot grow. Additionally, if your tanks are not exposed to sunlight, algae are less likely to colonize them. As a result, algae are less likely to collect in your tank, and when they do, they die.


Bleach should be used to eliminate the algae. You can use bleach to eradicate algae if you have a problem. 1/4 or a quarter teaspoon per gallon of water in your tank should be the recommended ratio. Bleach is a wonderful disinfectant for removing algae (and other organisms that may be lurking in your tanks) and preventing its regeneration. Bleach made from a solution containing 5.25 percent hypochlorite is effective in scientific studies. Bleach and chlorine should never be mixed. This mixture is also known as chlorine gas, which nobody wants.


Chlorine is an effective algae growth inhibitor and is also used by your local southwestern water company. To 1,000 parts water, you should add four parts chlorine. When the amount of chlorine used is not excessive, the water remains potable and does not taste bad.


It is vital to monitor the bleach-to-water and chlorine-to-water ratios very closely. This will eliminate or significantly slow the growth of algae while still maintaining a clean water supply. You can simply prevent algae growth in your tank by following these guidelines. Collecting rainwater is pointless if algae are allowed to grow on it. Even using a robust and durable water treatment tank lining will be ineffective if algae have invaded your tanks.


You should do this sanitization process on your tanks every six months to a year to help avoid the accumulation of contaminants and algae in the first place. Because algae are highly unlikely to grow in freshwater tanks, keeping them clean should be straightforward if you adhere to a regular sanitation schedule. If you follow the directions above, you should end up with an algae-free freshwater tank.
