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.
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. Always test the residual chlorine level with a chlorine test strip.
Add the Chlorine
Generally, you should maintain the pool's chlorine level between 1 and 3 ppm. Thus, if the chlorine level is already 1 ppm and you want it higher, add 0.00013 ounces per gallon to raise the chlorine by 1 ppm.
Example – A 50,000 litre pool will require up to 200 grams of chlorine and if 5 people use the pool a further 50 grams of chlorine is required = total of 250 grams per day.
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.
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).
Use 1-3 tablets at a time, depending on your pool size. You'll need enough to establish and maintain proper chlorine levels. Small Intex pools under 12′ in diameter should use 2-4 of the 1″ tablets in a chlorine floater.
You'll need to know how much water your pool holds in order to determine the right amount of chlorine to add. For a quick estimate, measure your pool's length and width, find the average depth, then multiply length by width by the average depth.
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.
Liquid chlorine may be a good choice if you have a large pool, but the costs associated with it, and the available chlorine per pound could mean that chlorine granules are the better option. In the end, both liquid chlorine and chlorine granules will do their job and keep your pool clean and clear.
Super chlorinate (shock) the pool ideally with liquid chlorine to shock level to 20ppm of Free Chlorine using either Liquid Chlorine (1.5L per 10,000L) or Chlorine Granules (310g per 10,000L). Run the filtration system on 'Recirculate” for 1 hour to allow the chlorine to spread throughout the pool.
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.
In the industry it is recognized to have the pool run for 3 hours at a bare minimum up to 24 hours. 24 hours really is overkill but it'll ensure the water is completely mixed with the chemicals.
Depending on its levels of content, the evaporation time for chlorine from tap water can be estimated: 2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water.
Chlorine Floaters: For each 5000 gallons of pool water, add one 3″ chlorine tablet. Open the baffle or vent at the bottom, fully open. The wider open, the greater the dissolution rate. Your test kit will tell you for sure if you are using enough chlorine tablets.
Answer: Yes, when using tablets they can be present in the water while you swim. Also confirm with a test of the chlorine level to be sure the sanitizer level is safe for swimming.
Although inflatable pools don't need to use chlorine, it's one of the most common ways to keep pool water sanitary and safe to swim in. The chlorine is used to efficiently kill bacteria in the water that may be harmful to swimmers. Larger inflatable pools will benefit the most from the use of chlorine.
It Should Not Be Done Together
This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
