Rowan said white vinegar is also a "practical and effective way" to remove algae from outdoor tiles. He continued: "Simply spray it onto the algae and let it sit for less than an hour. "Once it has penetrated the spot, the acidity will break down the algae, then scrub the surface with a stiff-bristle brush.
Q Here in the Pacific Northwest, one solution I have found effective in the removal of algae from our brick patio is to spray the surface with apple cider vinegar. I use a pump sprayer early in the spring on a dry day, and it lasts the entire year. The vinegar smells for a short time, but leaves nothing to wash off.
Bleach is great for killing algae (and other organisms that may lurk in your tanks) and for keeping it from coming back.
If you have an algae problem, your best friend is white vinegar. White vinegar can quickly kill algae but is not harmful to birds, insects and the majority of plants. Use a mixture of one part water to one part white vinegar to spray down the area and kill the algae.
To remove algae from a fence using vinegar, ensure a small amount is mixed with some water before spraying the mixture onto the algae - and after 30 minutes, it will look as good as new. It can be purchased from supermarkets for as little as 29p.
Shock Your Pool
Shocking is the process of adding chemicals to your pool to raise chlorine levels and kill bacteria and algae. We recommend using a calcium hypochlorite shock to treat your algae problems.
Barley straw. Barley straw is a natural way to fight algae. On contact with water, the straw starts to break down, and as it does so it releases peroxides into the water which combat algae. Available in mini bales, or as a concentrated extract of barley straw liquid, it's a natural way of chemically fighting algae.
Amy Caner agreed: "Definitely white vinegar. Easiest and most effective way to get rid of it." Lindsey Hall added: “I use white vinegar diluted with water to remove algae from my fence and it doesn't even take the paint off."
Hardware stores and home centers sell products designed to kill moss and algae, but you can save money by using inexpensive chlorine bleach or a non-creamy hand dishwashing detergent, such as Dawn.
TIP 5: USE BLEACH OR VINEGAR
Oxidized bleach immediately starts to kill algae cells once it comes into contact with it. Bleach, however, should not be your first option, especially if the area you plan to rid of algae is near plants or grass.
Another chemical-free solution that you can consider is a mixture of baking soda, water and vinegar. Add two parts of white vinegar to one part of water and three heaped spoons of baking soda. Dip a scrubbing brush into the mixture and apply it to the algae stains on your furniture. Leave it for about ten minutes.
But as it turns out, copper pennies do a pretty good job of keeping algae away for a few days! Pennies made before 1982 contain copper and according to Google, “copper kills algae by binding to it, which damages the algae cells, causing them to leak and die.” I tossed in 10 pennies and waited for the results.
Don't use more than the prescribed amount because it can cause the algae to die off too quickly, leading to an ammonia spike which is dangerous for fish. The peroxide will take effect within a few minutes, and the increased oxygen will last for a few hours.
To eliminate and prevent green algae in a swimming pool, start by adding an extra dose of chlorine to your pool to shock the algae and stop the bloom. Let the chlorine work overnight, then test the pH levels of the pool in the morning to see if the pH is back to normal.
Metallic pool algaecides like silver algaecides are especially effective on black and yellow algae. Metallic algaecides are the most powerful of the three, therefore can be expensive. Most metallic algaecides are made with copper which can cause staining of pool walls and hair.

This pool idea is loved by experts who recommend using this homemade remedy to increase the alkalinity and pH level of your pool – and treat black algal growth on your swimming pool wall.
When added to water containing algae, H2O2 breaks down into water and oxygen, releasing free oxygen radicals in the process. These free oxygen radicals can then react with and destroy the cell walls and membranes of algae cells, causing them to die off.
Since baking soda is highly alkaline and reacts when mixed with an acid, many people assume it can be used to change the pH of a pond to discourage algae growth. However, even a large amount of baking soda dissolved in a pond will have little to no effect on either algae or pH.
