What can you add to the pool to increase the free chlorine levels?

If you are adding chlorine and it is dissipating with in hours, you may need to stabilize your pool by adding cyanuric acid. If your free chlorine is lower than your total chlorine, its time to shock your pool.

The free Cl level will always be lower than the total level, because the latter means the combined locked (ineffective) and active chlorine.
The chlorine is dissipated by sunlight (UV radiation) and of course by its reactions with bacteria and impurities. Isocynauric Acid minimises the former but not the latter (obviously!).
You can buy chlorine donors with cyanuric acid stabiliser already added. The trade or generic names include "Trichlor", "Troclosene", etc. Using this avoids both having to store a second chemical and having to calculate its own dose.
Be careful though: the stabiliser does not break down in normal service, and if allowed to accumulate will eventually stop the chlorine from working. When that happens the only solution is to drain and refill the pool. You can buy test kits that measure the Cyanuric Acid level: I think from memory the maximum concentration before it starts to cause real problems is about 180ppm.
Don't forget you still need to maintain the pH level to between 7.2 and 7.6, and correct it if necessary before adding any other chemicals.

Can you swim in a pool that has high free chlorine?
Chlorine levels should be between 1-5 ppm
What is free chlorine in a pool?
Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.
What is a safe chlorine for swimming?
Someone/something changed the original question and that is probably why it has not been answered.Safe levels for chlorine are 1.5 ppm to about 5.0 ppm. of free chlorine. You should have a test kit that will give you free chlorine readings as opposed to just a chlorine residual. Free chlorine is what sanitizes the pool water. If you can smell a chlorine odor coming from your pool then you do not have enough chlorine in the water.K
Do you need to santize pool after rat swims?
So long as the proper free chlorine levels are maintained you should have nothing to worry about. That is what the chlorine is meant to do.
What do you do if chlorine in saltwater pool is high?
Adjust your chlorine generator levels.
How do you reduce free chlorine in a salt water pool?
Free chlorine is the sanitizing portion of chlorine. You may not want to reduce that. Are the levels excessive? There is a product which reduces or eliminates chlorine but beware. Not a good product if you use too much. What are your readings?
Is a salt water or chlorine pool better?
A Salt water pool is a chlorine pool. The difference is that in the case of a saltwater pool there is a chlorinater fited inline that converts the salt into chlorine automaticaly, Meaning that you don't have to purchace any chlorine to keep up chlorine levels.
How long will it take a chlorine level to drop from 10 ppm to 3 ppm in a 7000 gal pool?
A few days. You will probably be able to use the pool when the level gets to about 5.0 ppm 1) you should know the difference between residual chlorine and Free chlorine 2) Chlorine lost depend on size of you pool and temperature 3) circulation of water , temperature & size of pool will increase chlorine lost
How much chlorine do you put in a15foot by 3foot pool?
I'm assuming 15 round? Not much, start with 4 ounces of granular per week, monitor levels to see where total and free is at. Make sure to shock weekly, too. A chlorine based shock is your chlorine levels need to be raised, or a non-chlorine oxidizer if your chlorine levels are above 5 ppm.
How do you filter out rainwater from an inground pool?
The rainwater will be treated by the chlorine in the pool and you may have to adjust the chlorine levels. See the related link for more information.
How do you lower chlorine level in a hot tub?
The easiest way is to just wait a couple of days the chlorine levels will drop on their own. Also, if you use a pool cover, leave it off. This allows free Chlorine to evaporate from the surface. === ===
Can you swim in pool hat has a normal chlorine level but the free chlorine level is high?
There is 3 measurements of chlorine in a pool or spa. Total chlorine, combined chlorine, and free available chlorine. Free available chlorine is the good chlorine that is active in the pool killings germs and algae. Combined chlorine is chlorine is basically chlorine that was once active but has killed germs or bacteria and is now inactive in the pool. Total chlorine is free available and combined chlorine added together. If your combined chlorine is higher than free available chlorine then the water needs to be shocked to eliminate the combined chlorine. But be careful here. If you don't reach what's called break point you will only add to the combined chlorine. There are products on the market which will only remove combined chlorine without effecting your free available chlorine if you are unsure about reaching breakpoint. Hope this helps.
