How long does it take for chemicals to work in a pool?

If you add chemicals to balance the water after testing, wait a full day – or even longer – before retesting. It takes about 24 hours for the chemicals to properly circulate in order to get an effective reading from the retest. The water test will assess the pH, chlorine, total alkalinity and calcium hardness.

How often do you need to put chemicals in a pool?

Factor #1: Regular Use This works out to once every day or two. Testing at this frequency should ensure you are able to keep free chlorine levels at recommended ranges of 2.0 to 4.0+ ppm, assuming no unusual activity or events cause a spike in contaminants.

What chemicals go in pool first?

Chemicals Needed for Pool Start Ups

• Stain & Scale Preventer.
• Granular Shock Chlorine.
• Chlorine Tablets.
• pH Increaser and/or pH Decreaser.
• Alkalinity and/or Calcium Increaser.
• Cyanuric Acid (Stabilizer)
• Algaecide and Clarifiers if needed.
• Complete Test Kit or Test Strips.

Should I shock my pool when I first fill it up?

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. Now it’s time to keep the water hardness in check, otherwise known as alkalinity.

Do you shock pool after rain?

Shock & Filter the Water Shocking helps sanitize any contaminants or materials that were introduced to the water during the storm. Run your system for at least 12 hours to ensure proper filtration and circulation. This removes dirt and debris, and also assists with circulating the chlorine throughout your pool.

What does a lot of rain do to a pool?

Heavy rains will dilute your pool alkalinity level, causing it to fall by 5-10 ppm a day. Low Alkalinity and low pH levels in pools can create a corrosive water environment. Corrosive pool water can result in the damage of underwater metal surfaces, such as pool lights, ladders and rails.

How often should you shock a pool?

about once a week
How Often Should I Shock My Pool? Shocking your pool regularly will help to keep the water clean and free of contaminants. You should aim to shock your pool about once a week, with the additional shock after heavy use. Some tell-tale signs that your pool needs to be shocked are cloudy, foamy, green, or odourous water.
