Five Tips for Keeping Algae Out of Your Water Tank

If you have a water tank or pond for irrigation or household use, algae may grow in it. Luckily, there are numerous ways to reduce the presence of algae in water tanks. Take a look at these ideas.

1. Don't Feed Ducks Bread

If your water tank is an open pond, you may have ducks or other fowl there. Although it can be tempting, you should not feed them bread. Uneaten bread can sit on the surface of the water and encourage the growth of algae. If you really want to feed the fowl, you should buy seeds designed for their intestinal tracts.

2. Block Sunlight

While many people use ponds, that isn't ideal if you're trying to prevent the growth of algae. Algae needs sunlight to grow and an open water tank or pond has lots of sunlight. Instead, consider using a concrete water tank. Ideally, it should have a cover or an access hole so you can get into the tank as needed, but its design should block as much sunlight as possible.

3. Opt for Light Colour Tanks

The temperature in your tank can also encourage algae growth. In most cases, the warmer the water, the more likely it is to encourage algae growth. Dark colours will attract and absorb heat from sunlight, and that can cause your water to heat up unnecessarily. Instead, consider getting a concrete water tank as concrete is relatively light coloured and has natural insulating abilities or another type of light coloured tank.

5. Add Chemicals

The right chemicals can also help to reduce or eliminate algae in your water. In most cases, both chlorine and bleach can work, but you should only use them separately, not together. You should consult with a water expert before adding these chemicals. You need to be very careful with them if you are drinking the water, and you also need to ensure you don't put in chemicals that can be hard on your plants.

5. Clean Out the Tank

If you find algae growing in your tank and you don't want to add chlorine or bleach, you may want to try emptying and cleaning the tank. Clean the sides of the tank with bleach to kill existing algae, but make sure to rinse well so that residue doesn't get in your water.
