Little-Known Ways of Preventing Algae Growth in Your Water Tank

Posted on: 31 August 2017


With numerous areas in Australia becoming drought stricken, rainwater harvesting has become an essential measure for households looking for an additional supply of water. This renewed interest in rainwater harvesting has translated in an upsurge of water tanks being installed in homes to store this water being collected safely. However, simply purchasing a22550-litre tank for your home does not mean you water troubles are over. You also have to ensure that your harvested water stays safe enough, especially if it is being used for consumption. One of the biggest threats to collected water is algae. As the algae breed in your tank, it produces bacteria that contaminates the water, making it harmful to animals and humans alike. Below are some of the little-known precautions that you can take to prevent algae growth in your water tank.

Invest in an opaque tank

Your first line of defence against the growth of algae starts with the type of tank that you purchase. Algae needs adequate amounts of light to start to grow. Therefore, it is prudent to select an opaque tank for your water storage needs. Also, ensure that the walls of the tank are not too thin, as this would allow some light to pass into your tank, particularly if it is going to be in an elevated position.

Select the right location for the tank

Australian weather tends to be predominantly hot all year round. This climate means particular attention needs to be paid to where the tank will be located. As a rule of thumb, make sure that the tank is shaded. Shade is crucial because high temperatures can create a suitable environment for algae to thrive, even if the algae is not receiving constant sunlight. If you do not have a shed on your property, you could either have one constructed or invest in a carport or tarpaulin that can cover your tank. Alternatively, you could have the tank installed underground, which would protect it from both direct sunlight as well as high temperatures.

Clean your tank often

A  mistake people make is assuming since the water in the tank is not being disturbed, the tank will not become dirty. In reality, there are various ways that organic debris can make its way into your tank, which will lead to the development of algae. It is crucial to invest in professional tank cleaning on a routine basis to safeguard your water. The professional cleaners will eliminate any contaminants collecting on the interior walls of the tank and can subsequently chemically treat your water to keep it free of algae.
