Can you over shock a hot tub?

The bottom line is that over-shocking is possible, but being responsible with your chemicals and timing will help you to avoid it as often as possible!

What do you put in a hot tub after every use?

Shock the spa using dichlor chlorine at a ratio of 1.5 tablespoons dichlor per 250 gallons. Test water with chlorine test strips, waiting until chlorine level has dropped below 5ppm before using the spa. After each use, add 1 tablespoon Oxy Spa per 250 gallons.

Will Shock raise free chlorine?

Total chlorine is simply the combination of free and combined chlorine. Shocking then releases the combined chlorine and off-gasses the contaminants, increasing the amount of free chlorine in your pool or spa.

Does adding chlorine increase pH?

Using liquid chlorine raises the pH of the water.

Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.

How do I fix a low chlorine level in my pool?

Does chlorine raise or lower pH in hot tub?

In most cases, adding chlorine to the swimming pool or hot tub water will lower pH levels. … Chlorine is a powerful chemical that can reduce the pH level of water in hot tubs. Therefore, it’s important always to add chemicals slowly and carefully, wait 20 minutes before testing again.

What causes high pH in 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.

Can too much chlorine damage your pool?

Having too much chlorine in your pool water can be dangerous. Exposure to high levels of chlorine can cause lung irritation, skin and eye damage, and provoke asthma. … High chlorine levels decrease the pH of your pool’s water, making it more acidic. The more acidic the water, the higher the likelihood of corrosion.

How long should you wait to use hot tub after adding chemicals?
