The honest truth is that every hot tub owner has accidentally over-shocked their hot tub at least once. It happens from time to time and it's not the end of the world. Try to keep it to a minimum, though, as it can damage your hot tub and actually harm your body, too.
Chloramines have a strong chlorine odour that is often mistaken for too much chlorine, they can make the water appear cloudy and also sting your eyes. ... Using Non Chlorine Shock in a hot tub running on Bromine will oxidise the bromide ions (spent bromine) and form new bromine, this boosts the bromine level.
If too much is added, it can cause the overall pH level of the pool to drop for a sustained period, which you'll then have to raise. Whereas, with a chlorinated shock, if you overdose the pool on it, all you have to do is wait a few extra hours for the sun to burn off the chlorine.
If your chlorine levels are very high after a shock or after adding too many chlorinating granules and you need to use your hot tub soon, you can use a chlorine neutralizer. ... A rise or fall in chlorine levels can affect the other chemical levels.
Measure 17g of non-chlorine shock per 1500 litres or 35g of chlorine shock per 1500 litres (consult the label instructions as this can vary based on chemical quality and brand). Carefully add the required shock to the hot tub. Leave the cover off for approximately 20 minutes.
After NON-CHLORINE shock wait 10-15 minutes before entering. After chlorine shock it can take up to 24 hours to clear. Therefore it is recommended to use non-chlorine shock.
It works to oxidize organic matter from dead skin cells, sweat, sunscreen, dirt, leaves, and other sources. It also oxidizes chloramine. Unlike chlorinated shock, chlorine-free has a pH level of 9 (neutral is 7).
Having pH levels that are higher than 7.8 or lower than 7.2 can cause problems for your and you hot tub. High pH is a common cause of calcium and scale build up at your hot tub water line and cloudy or dull water. It also causes bathers to often experience itchy skin and burning eyes.
When they are too high in a hot tub this can be uncomfortable for hot tub owners to sit in. High bromine/chlorine levels can be very irritating on a person's skin, eyes and respiratory system. It can cause red itchy skin, red itchy eyes, and effect the lungs in a negative way.
Adding chlorine besides the shock can increase the chlorine content in the water which can make the entire shocking process useless. Hence, it is better if you don't use the shock and chlorine at the same time. The best time to add chlorine to the pool water is after you have shocked the pool.
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.
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.
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.
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. You should wait 12 hours before entering the hot tub when you've added either chlorine or bromine to allow it to take effect properly.
One ppm of unstabilized chlorine will dissipate in 15 minutes or less under direct sunlight. With heated spa water, this dissipation rate is even faster. The loss can be controlled with a separate, one-time addition of CYA.
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.
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.
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.
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.
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.
Dichloroisocyanuric Acid: Also known as “dichlor,” this is another type of chlorine shock. Dichlor contains both chlorine and cyanuric acid and will, over time, raise your cyanuric acid levels.
Causes of cloudy hot tub water. When it comes to cloudy water, it's likely one of a few culprits — high pH, high alkalinity, and low sanitizer. Dirty filters, body care products, and old water can also be responsible for cloudy water.
