Does non-chlorine shock affect alkalinity?

Change to Total Alkalinity

When applied in significant quantities, non-chlorine shock can cause your pool water to have unhealthy total alkalinity levels. Furthermore, the total dissolved solids content will simultaneously increase.

Can I add non-chlorine shock and chlorine at the same time?

While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.

Does non-chlorine shock raise free chlorine?

That said, it should be noted that non-chlorine shocks don't kill algae, or raise the chlorine level. Your FAC level should be around 1.5 ppm for a non-chlorine shock to work effectively. If the pool has algae, or there has been a fecal accident, always use a chlorine-based product.

How soon can you go in hot tub after adding chemicals?

Chemicals in your hot tub water can be a delicate balance. So it's crucial to maintain the levels of pH, Alkalinity, and Chlorine or Bromine, also known as sanitizers.

Why does my skin burn after hot tub?

Chlorine, which is a hot tub sanitizer, can cause dry, itchy skin, redness, and hives. The condition is called irritant dermatitis and is similar to a chemical burn. Chlorine rash prevention, therefore, involves the management of hot tub water chemicals and self-care.

Why is my pH always high in my hot tub?

Hot tubs in particular generate a lot of bubbles and tend to have higher temperatures. This combination creates a gas called carbon dioxide very quickly. Carbon dioxide builds up and makes the pH go up. This is why hot tub owners, on a regular basis, need to add something to lower their pH and alkalinity.

Does high pH cause hot tub foam?

Foam will appear if the pH balance of your hot tub water is off. This is caused by using cheap chemicals or inaccurately mixing them. Water with low calcium or too much pH or alkaline can lead to cloudy water. If you use your hot tub frequently, you yourself could be causing foam to appear.

How do you fix a high pH in a hot tub?

In order to lower both the pH and alkalinity of your hot tub water, you will need to add acid. Common choices are liquid muriatic acid or dry sodium bisulfate. When the acid is introduced to the water, it increases the hydrogen concentration and lowers the pH.

How do you shock a hot tub with dichlor?

A. Chlorine-granular dichlor
  1. Regular use- add ½ teaspoon per 100 gallons after each use.
  2. Heavy use-add 1 teaspoon per 100 gallons after each use. If the spa goes unused for 3-4 days, add ½ teaspoon per 100 gallons.
  3. Special events, kid's parties, and use throughout the day: add chlorine throughout the day.
