  • 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.

Do you shock or put pH down in pool first?

Step 4 – Shock the Pool!



Equally important is to balance the water first, before shocking a pool. Minerals, metals and dirt often mix and deposit as stains or scale during shocking, when pool water is not balanced. In addition, chlorine has much more power or efficacy at lower pH levels, so you can use less.

Do I add chlorine or stabilizer first?

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.

Can I add pool chemicals at the same time?

You should not add all pool chemicals at the same time. You should also avoid mixing pool chemicals together. Adding chemicals at one time can cause dangerous chemical reactions and serious injuries. In addition, it will make it difficult to balance the pool.

You should always dilute your acid first. This way you can add it gradually and test your pH as you do so to make sure you’re not adding too much.

Can you add chlorine and pH at the same time?

The Orderly Addition of Chemicals



If both the pH and total alkalinity levels are too high, you’ll need to add pH reducer. Once you get your pH levels between 7.2 and 7.5 and your total alkalinity between 60 and 120 ppm you can move on to working on the calcium hardness and chlorine levels.

Should I add chlorine or muriatic acid first?

It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours. It is always best to test first! Muriatic acid can create a hot spot of acid in the water that could potentially burn or irritate your skin. It is best to wait 30 minutes after adding it to your pool.

What should be adjusted first alkalinity or pH?

What pool chemicals should not be mixed?

Incompatible Pool Chemicals



Mixing of organic chlorinating agents (such as trichloroisocyanuric acid) and inorganic chlorinating agents (such as sodium hypochlorite) can lead to fires, explosions and chlorine gas release.
