Boost it up to 30 ppm by adding 3 lbs of Stabilizer per 10,000 gallons of pool water, to protect free chlorine from the sun.
The most important factor though is the size of the pool. You'll need about 52-104 oz of liquid chlorine per 10,000 gallons of water. This amount should get the chlorine level to between 5 and 10 ppm.
At first you'll add chlorine in what's called “shock” levels – an extra heavy dose to start your pool off. A shock dose coupled with extra circulation will ensure that all the water gets treated properly in the beginning.
Add a clarifier to the water. The clarifier will help the filter to remove the very tiny particles that enter the pool in the filling process or that may remain following construction and installation. 5. Start the pump and filtration equipment and allow the water to circulate for 24 hours, if practical.
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2-4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
Your first instinct when you fill your pool with new water, is to shock it. But that shock then oxidizes the metals, that chemical reaction then causes the green hue in your water. This is common with refills that used well water or even water that hasn't been shocked but instead contains a high level of metals.
Open your pool under normal procedures, and let the filter run with its normal amount of chemicals. When all the other chemicals, such as chlorine. pH and alkalinity, are balanced, add the chlorine stabilizer. Add the stabilizer only after the filter has been backwashed to ensure it is cycled through a clean filter.
Before shocking the pool, be sure that you have properly balanced the Total Alkalinity, pH, and Calcium Hardness levels, and have addressed metals in the pool.
In theory, if you have a cloudy swimming pool, you can add chlorine to “shock it” and clear things up. Chlorine will get the job done. But, the amounts may vary and you may have to really pound the pool with chlorine to get the water totally clear.
Should the green be due to pollen, there may be little to do in the way of minimizing the discoloration short of erecting a building around the pool. Fortunately, assuming there are no allergies to the pollen, it is safe to swim in a pool with that as the cause for green water.
Baking Soda and Green, Blue, or Yellow Algae
You'll need to use an algaecide to kill the algae and superchlorinate your pool to clear the water. After this treatment, test your pH and alkalinity and add baking soda to raise alkalinity to at least 100 ppm and pH to between 7.2 and 7.8.
Wait about 20 minutes after adding balancing chemicals to your newly filled pool, and you should be good to swim. Calcium chloride – If you have hard water issues, it's advised to wait about 2-4 hours before swimming after adding calcium chloride to soften your pool's water—or until one filter cycle has been completed.
Acid washes are ideal for minor discolorations caused by things like leaves falling into the pool. The main benefit of acid washing, during some new finishes application is to remove any haze or cement residue.
For the greatest protection against algae, bacteria, and cloudy water, Intex pools should maintain a chlorine level of 2.0-4.0 ppm at all times. If you opted for the Intex Salt Chlorinator, you can make your own chlorine by adding the correct amount of Pool Salt to the water.
2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water. Ultraviolet light, water circulation, and aeration will speed up the evaporation process dramatically. Chlorine will last between 6 and 8 minutes in 10 gallons of boiling tap water.
The procedure for adding granular chlorine is pretty much the same as adding calcium chloride or sodium bicarb to a pool. Measure the dry chemical, pre-dissolve in a bucket, and pour around the perimeter of the pool (never into the skimmer directly).
Pool water turns green because of algae in the water. Algae can grow rapidly, particularly when it's warm like Summer, which is why it can surprise you overnight. This generally comes down to an imbalance or lack of chlorine in the water.
So if the pool water isn't cloudy and the 'dirt' is clinging to the walls after brushing, the problem is likely be yellow/mustard algae. Yellow/ Mustard algae is very resistant to even high chlorine levels and will grow and thrive in a chemically well-balanced pool.
High doses of chlorine, like pool shock, can cause temporary cloudiness as it kills contaminants. High levels of pH, alkalinity, and calcium hardness are more likely to cause cloudy water.
Skim the top of the pool for debris that may have settled on the pool surface. Add one pound of diluted granular shock to the water for every 7,000 gallons of pool water. Run the filter for 24 hours and retest the water. The slimy looking film can be an early onset of algae.
