Add the granules to the water; don't pour water onto the granules. Pour the mixture around the edges of the pool. You can pour liquid chlorine around the edges of the pool. You can also pour it in front of the water return from the pump to distribute it throughout the pool.
Yes, either in the skimmer basket (tabs or liquid) or pour (liquid) in front of the return with the pump running. Wont hurt a thing- just be sure to circulate the water while and directly after adding any chemicals.
Add enough chlorine to bring the level to 8 ppm.
Remember to test your pool water before adding any chemicals to it. Once you've measured and, if necessary, diluted the right amount of chemical, add it gradually to the pool. Pour it slowly as you walk around the pool's perimeter to ensure even distribution.
Granular chlorine: It should be dissolved in a bucket of water before adding it to the swimming pool.
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2–4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
Granular chlorine, liquid chlorine, chlorine tablets and granular shock all have similar active chemicals that sanitize your pool. What's different about shock is the strength of the chemical and how you're supposed to use it.
It's best to add chlorine to your pool at night, so it can work while no one is swimming and the sun has set. If you use a slow-dissolve chlorine treatment like a tab, adding it at night gives it time to dissolve, so the pool will be ready to face the day.
Statistically, a pool without chlorine is more likely to make you sick because of the possibility of being exposed to the things not contained or killed by chlorine. Remember, your skin is porous, so microscopic impurities can pass through. A pool sans chlorine is akin to a big puddle of murky water.
While it may be tempting to toss chlorine tablets into the skimmer for convenience, doing so can have serious repercussions for your pool and equipment. From fluctuating chlorine levels to corrosive water chemistry, and equipment damage, the pitfalls of skimmer placement far outweigh any perceived benefits.
How much chlorine to add depends on the type you're using. But since tablets are the most common, we can say that the rule of thumb for how much chlorine to add is two 3-inch tablets per 10,000 gallons, or one 3-inch tablet per 5,000 gallons.
In The Skimmer
It has long been believed that the ideal place to put your chlorine tablets is in your pool's skimmer. As the water filters through, it will disperse the chlorine and keep your water at the appropriate level between 1-3 ppm.
Having too much chlorine in the pool can be dangerous. Not only is it bad for your overall health, but it can also cause problems for the equipment and finishes in the pool. Improper maintenance of chlorine levels in the pool can lead to several issues and cause pain and discomfort to you and your family.
You can pre-mix chlorine granules in a 5-gallon bucket that's 3/4 full of pool water. Add the granules to the water; don't pour water onto the granules. Pour the mixture around the edges of the pool. You can pour liquid chlorine around the edges of the pool.
Generally, it's recommended you add shock to your pool: When first filling up your pool. After spotting any signs of algae or slime. After any period of heavy use.
If you need to shock your pool, it's important to treat the pH balance first and ensure it's between 7.2 and 7.6. Chlorine will be mostly wasted if the pH balance is off. Powder or liquid is generally used for this step, but you'll need to mix it with some water in a bucket first to help it spread throughout the pool.
Shock the pool by adding 1 lb to 5 lbs of granular chlorine shock per 10,000 gallons, depending on the condition of the water (see above). Vinyl pools should always pre-dissolve chlorine pool shock into a bucket filled with water, before pouring the solution around the pool edge.
If the swimming pool isn't used much, be sure to check the water quality once a week using a water tester. If the pool is used more than 2 days a week, the water quality needs to be checked 2 to 3 times a week. If the pH value is good, check whether the chlorine tablet has completely dissolved or not.
You should not add chlorine and shock at the same time, as it's largely redundant to do so.
Raising pool chlorine can be much easier than trying to lower chlorine levels. Simply adding chlorine in the form of chlorine tablets, granular chlorine, liquid shock or powder shock will increase the total amount of chlorine within the pool.
If you're adding your regular doses of chlorine (i.e. not shock), a good rule of thumb is to wait 4-8 hours or until the water has experienced 'turnover' and has been cycled through the whole system. If you're shocking your pool, you'll have to wait longer.
