Can you use too much non-chlorine shock in the hot tub?
Chloramines have a strong chlorine odor that is often mistaken for too much chlorine, they can cloud the water, and they can also sting the eyes. Using chlorine-free shock in a bromine-supplied spa oxidizes bromide ions (spent bromine) and forms new bromine, increasing bromine levels.
What happens if you add too much non-chlorine shock?
Adding too much can cause the pool's overall pH to drop for a longer period of time, which you will need to increase. As for chlorine shock, if you overdose from the pool, all you have to do is wait a few extra hours for the sun to burn off the chlorine.
What happens when you put too much shock in a hot tub?
If your chlorine levels are too high after a shock or after adding too much granular chlorine and you need to use your spa soon, you can use a chlorine neutralizer. ... An increase or decrease in chlorine levels can affect other chemical levels.
How much non-chlorine shock should I use?
Measure 17g of non-chlorine shock per 1500 liters or 35g of chlorine shock per 1500 liters (see label instructions as this can vary by chemical grade and brand). Carefully add the necessary shock to the hot tub. Leave the cover for about 20 minutes.

Can I shock and chlorine in the hot tub at the same time?
Adding chlorine to the shock side can increase the chlorine level in the water, which can render the entire shock process useless. So it's better not to use Shock and Chlorine at the same time. The best time to add chlorine to pool water is after shocking the pool.
Does non-chlorine shock affect alkalinity?
Switch to full alkalinity
When used in significant amounts, non-chlorine shock can leave pool water with unhealthy total alkalinity levels. Furthermore, the total dissolved solids content increases at the same time.
Can I add chlorine-free and chlorine-free shock at the same time?
While quenching and adding algaecide are effective in killing algae, they should not be used together. Because if you mix chlorine and algaecide, they both become useless. Therefore, you should shock the pool first and wait until the chlorine level drops below 5 PPM.
Does a non-chlorine shock increase free chlorine?
However, it should be noted that non-chlorine shocks do not kill algae or increase chlorine levels. Your FAC should be around 1.5 ppm for a non-chlorine shock to work effectively. If the pool has algae or if there is a fecal accident, always use a chlorine-based product.
How soon can you get in the hot tub after adding chemicals?
The chemicals in your spa water can be a delicate balance. Therefore, maintaining pH, alkalinity and chlorine or bromine levels, also known as disinfectants, is critical. You must wait 12 hours before getting into the hot tub after adding chlorine or bromine for it to work properly.

How long does it take for chlorine to evaporate from a hot tub?
One ppm of unstabilized chlorine will dissipate in 15 minutes or less in direct sunlight. With heated spa water, this dissipation rate is even faster. The loss can be controlled by a single, separate addition of CYA.
Why does my skin burn after a hot tub?
Chlorine, a disinfectant for hot tubs, can cause dry, itchy skin, redness, and hives. The condition is called irritant dermatitis and resembles a chemical burn. Preventing chlorine breakout, therefore, involves managing chemicals in spa water and self-care.
Why is my pH in my hot tub always high?
Hot tubs, in particular, produce a lot of bubbles and tend to have higher temperatures. This combination produces a gas called carbon dioxide very quickly. Carbon dioxide builds up and causes the pH to rise. Because of this, hot tub owners need to add something regularly to lower the pH and alkalinity.
Does high pH cause foam in the hot tub?
Foaming occurs when the pH of the spa water is not correct. This is caused by using cheap chemicals or inaccurate mixing. Water that is low in calcium or very high in pH or alkaline can result in cloudy water. If you use your hot tub frequently, it could be causing the suds to build up.
How do you fix a high pH in a hot tub?
To lower the pH and alkalinity of your spa water, you need to add acid. Common alternatives are liquid hydrochloric acid or dry sodium bisulfate. When acid is introduced into water, it increases the hydrogen concentration and lowers the pH.
How do you shock a hot tub with dichlor?
A. Chloro dichloro granules
- Regular Use - Add ½ tsp per 100 gallons after each use.
- Heavy Use - Add 1 tsp per 100 gallons after each use. If spa will not be used for 3-4 days, add ½ tsp per 100 gallons.
- Special Occasions, Kids Parties and All Day: Add chlorine throughout the day.
Is free chlorine the same as shock?
Total chlorine is simply the combination of free and combined chlorine. The shock then releases the combined chlorine and releases the contaminants, increasing the amount of free chlorine in your pool or spa.

FAQs
What happens if you add too much non-chlorine shock? ›
If you use too much non-chlorine shock, you can cause your alkalinity and pH to decrease. And that means you may need to add something, like pH increaser, to raise the pH level back to between 7.4 and 7.6.
Can I shock if free chlorine is high? ›If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
How much non-chlorine shock to add? ›There are a lot of potential benefits to non-chlorine shock. It dissolves immediately upon hitting the water and leaves no residue. You need about 1 pound per 10k gallons of pool water. It works to oxidize organic matter from dead skin cells, sweat, sunscreen, dirt, leaves, and other sources.
What does chlorine free shock do? ›Non Chlorine Shock will oxidise oils such as body oils, lotions, deodorant, dead skin cells, sweat, detergents or leaves from your hot tub water, helping to prevent or reduce foaming and to reduce strain on your hot tub filters. This can also reduce reliance on chemicals that should be used sparingly such as Anti-Foam.
How long does it take for chlorine shock to work? ›You need to wait for at least 8 hours and up to 24 hours after using a chlorine-based shock before you can swim. And you'll want to retest your water to make sure your chemical levels are within range. If your free chlorine is at or below 5 ppm and your pH levels are at or below 7.6, it's likely safe to swim.
How long does it take for free chlorine levels to drop? ›Direct sunlight breaks down chlorine. Without a stabilizer (cyanuric acid) in the water, as much as 90% of free available chlorine could be destroyed within just two or three hours.
Can free chlorine be higher than total? ›If the readings are the same, then no Combined Chlorine is present. The Total Chlorine level cannot be less than the Free Chlorine level. Once you know how much Combined Chlorine is in the water, you add about 10 times that amount of Free Chlorine to get rid of it.
Why is my free chlorine low after shocking? ›There are several reasons why your free chlorine levels are still low after shocking your water: Other pool chemicals are out of balance: Without the right amount of pH or cyanuric acid in your water, your chlorine levels can fluctuate.
