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.
Vinegar can also be used to remove mineral deposits from a pool, shine up metal surfaces, clean your pool filter, and get rid of algae and other things growing in your pool. You can use a vinegar solution and scrub brush to accomplish most of this and use undiluted vinegar for stubborn stains.
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.
In the same way that baking soda can be a spot treatment for black algae, household borax does the same for blue and green algae. Simply use the borax to scrub away algae that's sticking to your pool walls, then use the brush to dislodge it. Follow up by vacuuming up or scooping out the free-floating algae.
Adding shock to your pool super-chlorinates your water. And this extra dose of sanitizer will kill algae growth. The more serious your pool algae problem, the more shock you'll need. We recommend using calcium hypochlorite shock, or cal-hypo shock, as an effective algae treatment.
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.
Using baking soda in your pool is one of the easiest but most efficient ways to get your backyard ready for summer. 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.
This is most effective for algae like Staghorn. Every time i have used the H2O2 to kill Staghorn algae, i've had a 100% success rate. It also makes a difference for algae like fuzz, spirogyra, brown hair algae and other hair algae types.
Only algaecides can "kill" algae in pool water. However, baking soda can help clear up algae. Use both so you can restore sparkly, clean water!
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.
Chlorine is still one of the most effective killers of algae so doing a super-chlorination of 10-20 ppm of chlorine can go a long way towards wiping out the algae. Liquid chlorine is an ideal shock for algae because it is fast acting and does not add cyanuric acid (CYA) or calcium to the water.
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.
You can use a bleach and water solution made with Clorox® Disinfecting Bleach for cleaning algae and mold from exterior sealed non-porous surfaces like stucco and painted wood, siding, tile, brick and patio stone. In some cases, bleach and water are all that's needed to clean away mold and algae.
In the case of blue-green algae: Use 1.5 to a maximum of 2.5 ml of the 3% solution of hydrogen peroxide per gallon of water. In the case of green algae: 20.25 ml to a maximum of 32.5 ml of the 3% solution of hydrogen peroxide per 13 gallons of water.
The truth of the matter is: hydrogen peroxide is another dangerous chemical just like chlorine. This particular system requires high levels of hydrogen peroxide to be effective. At these levels it becomes an irritant and will oxidise skin, hair and swimsuits. It can also cause respiratory problems.
A rule of thumb is 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool's pH tested below 7.2, add 3-4 pounds of baking soda. If you're new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.
Use a pool brush to vigorously scrub any pool surfaces covered in algae, including the walls, floors and steps. Apply a green algaecide according to the directions on the label. Let the water circulate for 24 hours, then brush the pool surfaces again. Vacuum or backwash to remove any remaining dead algae.
However, adding too much baking soda might also raise the PH level of your pool to an undesired stage (alkaline). In the case where too much baking soda is added to hard water, it can cause a build-up of calcium around your pool.
Scrub the black algae away with a good, stiff pool brush. This will help break down the protective layer and make it easier to treat. Break a chlorine tablet in half and rub it directly onto the affected areas. The chlorine treatment will kill the algae's roots and prevent it from coming back.
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.
Once algae gets into your pool water, they can turn into an algae bloom if you have nitrates, out-of-balance chemicals, warm temperatures, sunlight, carbon dioxide, or phosphates. Poor water circulation, poor filtration, and not sanitising your pool will also contribute to rapid growth.
