The two results should equal each other under normal conditions.

0.5 mg/l (0.0 to 10.0 mg/l range) free chlorine number of tests: Oxidizers will destroy chloramines and reduce waste by literally burning it off and will. I just tested my pool and the results are as follows:

Your chlorinator is turned up too high. At this level, there is enough free chlorine in the water to neutralize all the chloramines in the water. This results in diminished disinfecting capabilities compared with free chlorine.

As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.”. If total chlorine is higher than free chlorine, there are contaminants in the pool. Have your authorized sustain dealer test your pool water's stabilizer level.

Free chlorine, combined chlorine, and total chlorine can be easily understood with the following equation: If you have a free. If free is the same as total, then you are in range.

0.0 to 3.5 mg/l (ppm) high range: If the water's free chlorine level is too low and its combined chlorine level is too high, your pool isn't as clean as it should be. Total chlorine is a measure of all the chlorine in the water and free chlorine is the chlorine that actually sanitizes the water.

In other words, none of the chlorine has been utilized yet. Fac + cac = tc To fix the problem, the goal is to reach a point called breakpoint chlorination.

Were improving i guess, fc was at 10 for 3 days. If it is low, you will use a chlorinated shock. While free chlorine has a much higher disinfectant.

Total chlorine is the amount of chlorine, used or not, in your water. When too much chlorine is added to the water, a safe pool can become a pit of harmful chemicals.

Luckily, total chlorine is an easy enough concept to grasp. Chlorine compounds together with chloramines form combined chlorine. I have a 18 foot round pool and i seem to be having chlorine demand i test the water and i get no chlorine reading i took a sample to a local pool store and they said my total chlorine was at around a 3 and my free was at 0 my ph and alkalinity reading are fine my cya is a little high at 80 but it read that last year and didn’t have this problem i added powder chlorine and then.

I know that i need to bring the ph down and the ta. To fix the problem, the goal is to reach a point called breakpoint chlorination. Here the difference between those two types indicates your pool water has combined chlorine.

Therefore, it is good to deal with combined chlorine while it is still small. This can be done by adding your weekly dose of an oxidizer like beachcomber carefree, mineraluxe oxygen or beachcomber ultra shock. 0.1 mg/l (0.0 to 3.5 mg/l range);
