"Heavy rain dilutes pool chemicals, especially salt and chlorine, which causes the pool to turn green. This means the water is not sanitised or healthy, so it's vital to address this.
Should the green be due to pollen, there may be little to do in the way of minimizing the discoloration short of erecting a building around the pool. Fortunately, assuming there are no allergies to the pollen, it is safe to swim in a pool with that as the cause for green water.
The use of baking soda in pools can spot treat algae
No one ever wants to see algae build up in their swimming pool. It can turn any backyard pool murky green or cause unsightly black spots on the walls and floor of any swimming pool.
When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there's not enough. But be careful—adding too much chlorine in pool water can cause those metals to oxidize and turn the pool a different shade of green.
Pool water turns green because of algae in the water. Algae can grow rapidly, particularly when it's warm like Summer, which is why it can surprise you overnight. This generally comes down to an imbalance or lack of chlorine in the water.
Bleach, like any other kind of pool treatment, is best used in specific concentrations -- that is, you'll want to be able to detect a certain amount of chlorine in your pool water. Too little, and you won't effectively sanitize your pool water and surfaces. Too much, and your pool water might become too harsh to use.
Household bleach, Clorox and liquid chlorine can all be used to sanitize a pool. They are all types of chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine. Household bleaches often have unwanted fragrances and colors.
A pool turns green when there is algae in the water. There are several reasons why algae could grow, but it is most commonly caused by prolonged exposure to the sun, rain and temperature spikes. These factors affect the chemical balance of the pool and result in the pool turning cloudy and/or green.
ADD POOL CLARIFIER
The change in your pool water colour means that you have successfully eliminated the algae and can now clean it out of your pool. If your water is still green, wait another 24 hours and redo the steps from Days 1 and 2.
Set up your waste line and vacuum the pool to waste getting the algae and debris out of the pool. Don't let the water level get too low during this process, if it gets more than 6 inches below the tile, stop. Turn the system off and refill the pool and repeat until the whole pool is vacuumed.
They are identical in every way, with the exception of strength. Household bleach is usually a 6% concentration (although some of the cheaper stuff is 3%), while pool chlorine can typically be found in strength between 10% and 12%. All of this is sodium hypochlorite, and works the same in sanitizing your water.
Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
After your cyanuric acid level is set, add the bleach. Then proceed with daily testing until you understand how much chlorine your pool uses. At this point, chlorine maintenance can be as simple as adding a little bleach to your pool every day to keep it within the target levels.
Answer: It is true that pool chlorine is stronger than bleach. For bleach and water to be the same strength as pool chlorine and water, you would have to adjust the ratio, increasing the bleach and reducing the water.
Swimming pool shock contains 12.5% sodium hypochlorite (bleach) vs. 6-8.5% for Clorox (bleach). Some Clorox products go as high as 8.5%. At a 12.5% concentrate, liquid pool shock is approximately 2x's stronger than Clorox bleach.
Clorox is a bleach product from a company by the same name having its headquarters in Oakland, California. Though the company makes several chemical products, it is its bleach that is most popular.
If you need to calculate how much bleach or Clorox you need to shock your pool, you will have to use 1/2 gallon of bleach per 10,000 gallons of water to raise the chlorine levels by 5 ppm.
Daily as needed and indicated by measurement. One caveat, however: if your total alkalinity and pH are not where they should be, you will find it difficult to keep enough free chlorine in your pool water. Adjust your alkalinity first, then correct your chlorine.
It can, therefore, be concluded that bleach can be used in your pool as a substitute of chlorine. Can I use bleach in my pool? Yes. Bleach, just like chlorine, will release HOCL into the water and keep it clean and safe.
