A pool can show low levels of chlorine if the cyanuric level is below 50 ppm
parts per million. Cyanuric acid or conditioner is important to allow clorione
to stablise from ultraviolet light that breaks down chlorine. Chech to make sure you have the proper level of stabilasert (cyanuric).
Add chlorine
Chlorine tabs are for use in a chlorinator - there's some that just float in the pool and some that are connected to the water line and so are "automatic". They are a slow delivery system to help maintain the chlorine level in the water between 'shocking' the pool.
measure the pH level
The level of total dissolved solids in water does affect chlorine disinfection. That's why there is a recommended specification for the level of total dissolved solids in water for the water that is sent to homes.
You add water to the pool
Nothing you just wait for it to go down. if you have a salt water pool there is usually an aadjustment to reduce the chlorine level,
Cl is an abbreviation for "chlorine" you should check free chlorine and total chlorine for comparison.
beacause chlorine is a chemical used to clean water
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
Pulmonary edema is water on the heart or lungs. This can be causes by very high levels of chlorine, which break down the cell walls and allow water in where it should not be.
Your chlorine level needs to be increased to 3-5ppm and kept at that level. This will help you control them.
You can either remove some chlorinated water and add fresh water or you can just wait because chlorine levels drop on their own over time and from sunlight.
