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.
As a rule, you don't add more than 2.5 pounds of baking soda in a day. Instead, start off adding the required amount (e.g., 1.25 for 10,000 gallons of water) of baking soda that can raise the alkalinity of your pool to 10ppm. You can sprinkle your baking soda over the surface of the pool, or you pour into a skimmer.
Grab a brush and some baking soda. Bicarbonate, the active ingredient in baking soda, is an effective spot treatment to help kill the algae and loosen it from the wall. Make sure you really get every last particle free; black algae has particularly long and stubborn roots which makes it a persistent strand.
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.
You will need to wait 6 hours to let the baking soda thoroughly dissolve into the pool water. However, you can often speed up the process by turning on the pool's circulation system.
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
Baking soda will also improve the stability and clarity of cloudy pool water. You'll want to add baking soda to your pool if the water has too much chlorine. Pool water of this nature can cause swimmers to have itchy skin and stinging eyes. In addition, it can corrode pool ladders, liners, and other components.
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.
Does baking soda kill algae in pools? 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!
Combining vinegar, water and baking soda is ideal for targeting the toughest algae stains and mould growth. In a large container, add two parts white vinegar to one part water and stir in three heaped teaspoons of baking soda.
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.
But he finds a homemade cleaning solution of white vinegar and water works for him. “Just mix equal parts of both in a spray bottle and give it a good shake,” he says. “Spray it onto the algae-covered area and let it sit for about 15 minutes. Then, gently scrub the surface with a soft brush to get rid of the algae.
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.
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.
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.
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.
For an isolated algae bloom, use granular chlorine to treat it. You can also get a brush, apply algaecide to the water, and scrub. If you have free-floating algae, you'll have to shock your pool. To start, balance your pool water to get your pH between 7.1 and 7.3.
When temperatures reach below 40°F algae growth is stopped, but it can still survive and become dormant over the winter. Pool algae will come back to life weeks before you decide to open 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.

Adults who are not pregnant can mix about half a teaspoon (tsp) of baking soda with at least half a cup of water to relieve temporary indigestion. However, the NCPC recommend using OTC indigestion products, such as Tums, rather than making at-home remedies. This lowers the risk of overdosing.
