Why is my free chlorine higher than my total chlorine?
If free chlorine measurements are higher than total chlorine using a DPD method, check the alkalinity and pH of the sample. … Higher amounts of bicarbonate in the water can cause small bubbles (looks like turbidity) to form which will increase the free chlorine results.
Does pool shock raise free chlorine?

What does free chlorine mean on a test strip?
Free Chlorine is the amount of chlorine that has not yet combined with chlorinated water to sanitize contaminants. … The easiest way to check your chlorine levels is with test strips. However, ideal free chlorine levels are dependent on cyanuric acid levels.
Is shock the same as chlorine?
Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock. … You should aim to keep the chlorine level at between 1 and 3 ppm.
How high does chlorine need to be to shock a pool?
A chlorine level of between 10 ppm and 30 ppm, sustained for several hours, is usually needed to remove algae, bacteria and chloramines. Super Shock can deliver 10 ppm per 10,000 gals, per 1 lb. bag, in good water conditions – you may need more.
