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.
How do you fix low free chlorine in a pool?
If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
Why is my free chlorine so low?
What causes low free chlorine in pool? Things that cause low free chlorine levels are excessive sunlight, high bather loads, and improper water chemistry. Not having enough chlorine in your swimming pool will also cause the little bit of chlorine that’s in there to be used up faster too.
How much shock Do I need to raise free chlorine?
When you’re shocking a pool, the goal is to raise the free chlorine level of the pool water to roughly 10 times the combined chlorine level.
How does lower chlorine raise free chlorine?
Tips to Lower the Chlorine Level in Your Pool Stop Adding Chlorine and Start Swimming. Use the Sunshine. Heat the Pool Water. Dilute the Pool. Use Hydrogen Peroxide. Use a Chlorine Neutralizing Product. Try Sodium Thiosulfate.
Why is my pool showing no chlorine?
If you test your pool water and can’t get a chlorine level reading at all it may be due to a very high chlorine demand. Contamination, low pH or low chlorine stabiliser levels could cause this situation. The water might appear cloudy, the pool walls be slimy or the pool may look relatively OK.
Does adding salt to pool increase chlorine?
Instead of adding chlorine to sanitize a saltwater pool, you add salt, and then a chlorine generator converts it to chlorine. For instance, low chlorine readings can indicate that you need to increase the chlorinator output or run it more frequently.
What does free chlorine mean on a test strip?
Free chlorine refers to the amount of chlorine that has yet to combine with chlorinated water to effectively sanitize contaminants, which means that this chlorine is free to get rid of harmful microorganisms in the water of your swimming pool.
Can I add shock and chlorine at the same time?
Adding chlorine besides the shock can increase the chlorine content in the water which can make the entire shocking process useless. Hence, it is better if you don’t use the shock and chlorine at the same time. The best time to add chlorine to the pool water is after you have shocked the pool.
Can you over shock a pool?
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. It’s likely to do that regardless of if you overshocked the pool or not.
What is the difference between shock and chlorine?
1) What is the difference between chlorine and shock? Chlorine is a sanitizer, and (unless you use Baquacil products) is necessary for maintaining a clear and healthy pool. Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly.
Why is free chlorine high?
Adding too much pool shock or putting too many chlorine tablets to the feeder can both result in very high levels of chlorine. Another common way to over-chlorinate a pool is to leave a liquid chlorine pump running all night – you’ll often come in the next day to discover a greenish-looking pool.
How do I know if I have chlorine lock?
The quickest way to determine if a chlorine lock is present is to perform a test for total chlorine and free chlorine. Total chlorine is a measure of all the chlorine in the water and free chlorine is the chlorine that actually sanitizes the water. The two results should equal each other under normal conditions.
What eats chlorine in a pool?
The chlorine in your pool acts the same way. Keep in mind, organic materials like algae, leaves, sunscreen, lotions, pee, poop, and etc., consume chlorine. As chlorine does its job, it is depleted in the process.
How do I raise the pH and free chlorine in my pool?
Chlorine sanitizes well in water with a pH below 7.2, but acidic water corrodes fixtures in the pool and causes discomfort for swimmers. So raise the pH with soda ash or baking soda if it’s too low.
How do you balance free chlorine and total chlorine?
If total chlorine is higher than free chlorine, there are contaminants in the pool. Subtract the free chlorine measurement from the total chlorine measurement to calculate the amount of combined chlorine (total – free = combined). If combined chlorine is higher than 0.5 ppm you should shock the pool.
Why do I have to add chlorine to my pool every day?
During the bathing season, the chlorine is “burned off” by the sun and when you are using the pool a lot, you also need to add up chlorine. As a rule, you must add chlorine every day to keep the right balance during the bathing season.
What to do if chlorine locks up?
How to fix chlorine lock Partially drain the pool. Partially draining your pool is probably the best choice since you should be doing it occasionally anyway. Non-chlorine shock. Non-chlorine shock oxidizes the water, restoring the balance and making it cleaner. Chlorine shock.
