In the heat of summer your pool can require 4 grams of chlorine per cubic meter of water (1000 litres) of water every day. For every person who uses the pool each day, you will require a further 10 grams of chlorine.
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).
56% - You will need 19g by weight or 19ml by volume of cal-hypo 56% to raise your pool chlorine levels by 1PPM per 10,000 liters of water. 65% - You will need 16g by weight or 15ml by volume of cal-hypo 65% to raise your pool chlorine levels by 1PPM per 10,000 liters of water.
Chlorine is present in most disinfected drinking-water at concentrations of 0.2–1 mg/litre (3).
What is the corresponding weight in pounds per gallon? Chlorine gas has formed into a liquid state. It weighs 19.75 lbs/gal.
To dose water in a tank with 5 mg/L chlorine use: 40 millilitres of liquid pool chlorine or 170 millilitres of bleach, for every 1000 litres in the tank.
In the heat of summer your pool can require 4 grams of chlorine per cubic meter of water (1000 litres) of water every day.
Quantity of water in the tank (in liters) = 785 x (Tank Diameter in meter)2 x (Height of water column) – All measurement in Meters. Quantity of bleaching power required: If the Bleaching powder contains 30% or more chlorine, then 5 gm Bleaching powder is required for proper disinfection of 1000 lits 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.
Find out the volume of your pool. This will give you an idea of how much shock you need. The general recommendation is to use 1 pound of cal hypo shock for every 10,000 gallons of pool water, and 10 ounces of sodium hypo with around 12.5% chlorine to sanitize your pool. Make sure the pool water is at its normal level.
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.
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.
Setting Up A Hot Tub
When a hot tub has been refilled, it is important to give the water a high dose of sanitiser. This can be done by adding 60g of chlorine granules per 1,500 litres of water to start the sanitation process and allow the level to drop to 3-5mg/l before using the hot tub.
Shocking a hot tub requires about 2 ounces (4 tablespoons)of chlorine for every 500 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.
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.
Regardless of how frequently or what system you use to add chlorine to the water, the chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool. Anything higher will make you to run the risk of red eyes and swimmers itch.
It takes about 5 milligrams of chlorine per litre to disinfect your tank.
For laundry bleaches: 1 gallon is required for every 1000 gallons of water, and there are 1500 gallons of water in the well. Therefore, 1 ½ gallons of laundry bleach is required to disinfect this well.
At what temperature does a pool freeze? Chlorinated and non-chlorinated pools freeze at the same temperature. However, salt water pools will freeze at a slightly lower temperature. It should also be noted that above-ground pools will generally freeze at a higher temperature than inground pools.
