To prevent algae from growing in your water tank, deprive it of sunlight, nutrients and stagnant water. Algae is a diverse amalgamation of aquatic organisms – living entities that use photosynthesis to produce food and thrive. So, removing everything necessary for photosynthesis is the only way to prevent algae in your water tank.
How to Block Sunlight From a Water Tank?
You can keep your water tank blocked from sunlight using opaque paints, covers, external shade, or even by burying the tank itself underground. Warm, stagnant water is the perfect environment for algae growth. So, using these methods correctly will ensure the water inside the tank is cold and protected from the sun’s rays.
What Paint Should I Use to Cover my Water Tank?
To coat your water tank to block sunlight, choose dark, opaque colours and a product compatible with the material of your water tank. Some paints won’t adhere to polyethylene and are prone to prematurely cracking or peeling. And lighter colours, while reflecting the sun’s rays, could allow some light to penetrate the tank. Dark colours absorb heat, which may raise the water temperature inside your tank. But they will block light far more effectively than brighter alternatives.
How Does a Water Tank Cover Block Sunlight From a Water Tank?
Specialised water tank covers insulate heat and provide UV-resistance. These properties help to regulate the water temperature and sufficiently block sunlight, keeping your tank cool in summer and warmer in winter. Some modern water tanks include an internal liner that eliminates light transmission and prevents algae from growing.
How to Shade a Water Tank?
Installing your water tank in areas with natural shade is the first option, such as under a large tree or on the north side of your building. However, if this is not an option, constructing a simple shelter, such as a shed or roof overhang, will protect your water tank from sunlight.
Why Should I Bury My Water Tank Underground?
Burying your water tank underground is an excellent way to prevent algae growth and promote temperature regulation. Keeping the temperature of your water tank steady ensures the water doesn’t freeze in the winter or (effectively) boil in the summer, conditions that can damage your tank and its plumbing. Not to mention, aesthetically, installing your water tank below ground is a discreet, space-efficient method of maintaining the visual appeal of your property.
Burying your water tank underground is a significant, often costly decision that you should thoroughly consider. The maintenance and repair processes are more challenging, and the potential for undetected leaks is higher. But burying your tank could ensure its interior is better protected.
How to Maintain Water Quality in a Water Tank?
Ensuring the water in your tank is continually moving and clean can help significantly inhibit algae growth. Algae thrives in still, mineral-rich environments. So, installing a pump or circulation system between draining and deep cleaning will ensure that no sediment or debris feeds the algae can settle.
Could Relining Help Prevent Algae in My Water Tank?
Relining your water tank can be a practical and cost-effective solution to prevent algae growth by creating a seamless, non-porous barrier algae can’t attach to. Relining creates a light barrier and eliminates the cracks and pits that algae thrives in. So, if you’ve exhausted your options and algae keeps reappearing, relining might be the way to go.
