In a clean, freshly filled 500 gallon wading pool, add a quarter cup of unscented household liquid chlorine bleach to the water. Then, at the end of each day, test the water and add an additional 1/8 to 1/4 cup, depending on the reading.
How much shock do I need to shock my pool? A simple ratio and a standard rule of thumb to follow when you shock your pool is to dissolve one pound of either calcium hypochlorite or sodium dichlor for every 10,000 gallons of pool water.
The basic balance of chlorine to water is between 1 and 3 ppm, or 0.00013 ounces of chlorine per gallon of water.
Since there are 600 drops in a fluid oz. of water, only 2 oz. of bleach would be needed in a 150-gallon kiddie pool ( 1200/600 = 2 oz.).
A general rule of thumb to shock chlorinate and disinfect a storage tank is to mix non-scented NSF-approved household bleach (5.25% chlorine) in the reservoir at the ratio of 1 gallon of bleach for every 1,000 gallons of water (i.e., 1 quart for every 250 gallons of water).
For the greatest protection against algae, bacteria, and cloudy water, Intex pools should maintain a chlorine level of 2.0-4.0 ppm at all times.
Shocking a hot tub requires about 2 ounces (4 tablespoons)of chlorine for every 500 gallons of water.
If the water is clean and clear, then add about 3 oz of liquid chlorine per 1000 gallons of water – while the pool filter is running. This should give you a chlorine level of about 3 ppm.
Answer: One tablet is all you need. Failed to get answers.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
“It's important to change the paddling pool water every day – drain it and let it dry at the end of the day and use an anti-bacterial spray to kill any germs so it is safe to use the next day.”
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.
What happens if too much shock is added? You cannot overshock a swimming pool or add too much. Adding too much shock or overshocking your pool will kill off algae. The negative of adding too much shock is it will upset the chemical balance of your pool.
12.5% Liquid Chlorine Pool Shock – Normal Dosage: 1 gallon of shock per 10,000 gallons of water. Shock Dosage: 2 gallons of shock per 10,000 gallons of water. Source: Champion Liquid Pool Shock instructions.
To use the right number of tablets, always round your pool volume up to the nearest unit of 5,000 gallons. For instance, your pool has a capacity of 20,000 gallons, you would add four chlorine tablets. But if your pool holds just 16,000 gallons, you'd still use four, three-inch chlorine tablets.
But excessive exposure to chlorine can cause sickness and injuries, including rashes, coughing, nose or throat pain, eye irritation and bouts of asthma, health experts warn. Instructions for safely chlorinating a pool usually call for a maximum of four parts per million when people are in the pool.
How Much Chlorine Should I Add to my hot tub? A chlorine level of between 3-5mg/l must be maintained in your hot tub at all times. The addition of chlorine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 1mg/l add 2g per 1000 litres).
In general, 2 teaspoons of chlorine per 200 gallons diluted in water and poured into a circulating tub will generally help raise chlorine levels quite quickly without overdoing it. You should test your chlorine levels every few days and adjust as needed.
How Long do Chlorine Tablets Last in a Hot Tub? Small 20g chlorine tablets will dissolve slowly over a period of 3-7 days depending on water flow, water temperature and hot tub usage.
Once the pool is full it's unlikely to have much (if any) chlorine. That's why it's recommended to use a “shock” or starter dose once you have your pool up. This will help prevent algae and bacteria from the get-go. You should allow 50g of chlorine granules per 1000 gallons.
