In general, 2 teaspoons of chlorine per 200 gallons diluted in water and poured into a circulating tub will generally help raise chlorine levels quite quickly without overdoing it. You should test your chlorine levels every few days and adjust as needed.
How much chlorine should I add to my hot tub? Aim to maintain a chlorine level of 3 to 5mg/l at all times. How frequently you add more chlorine will depend on your usage and bathing habits. It could be daily, every two to three days or weekly.
TABLET ADDITIONS CHLORINE:
2-3 TABLETS FOR 200-300 GALLON SPAS. 3-4 TABLETS FOR 300-450 GALLON SPAS. OVER 4 TABLETS ONLY IF HEAVY USE OR PROBLEM SPA. THE FLOATER SETTING SHOULD BE 2” TO 3” OPEN FOR BROMINE.
You only need a small amount of chlorine to successfully sanitize your spa, so it's possible to overdo it if you're not careful. Too much chlorine can damage your hot tub and irritate your skin, eyes and lungs.
Again, as a general rule of thumb, people should wait at least 30 minutes after adding chlorine before getting in the hot tub. Those who use bromine might have to wait a little while longer. Make sure the hot tub cover is off, allowing chemical vapors to escape.
How Long do Chlorine Tablets Last in a Hot Tub? Small 20g chlorine tablets will dissolve slowly over a period of 3-7 days depending on water flow, water temperature and hot tub usage.
Measure out 2 teaspoons of chlorine for every 200 gallons of spa water. Add the chlorine to a bucket of water to dissolve, and then pour the bucket into the hot tub.
For a 300 gallon spa, 0.7 oz of Chlorine Granules shaken over the water surface, will raise the chlorine level up to about 10 ppm. This should be done with a balanced pH (in the low range of 7.2-7.4), and with the circulation pump running on high to help distribute the shock quickly.
A 150-gallon kiddie pool would need approximately 1,200 drops of bleach to disinfect the pool's water. Since there are 600 drops in a fluid oz.
This can be done by adding 60g of chlorine granules per 1,500 litres of water to start the sanitation process and allow the level to drop to 3-5mg/l before using the hot tub.
Regular hot tub shocking is inevitable to keep your water clean and safe for use. Dead skin and other elements like hair may end up dropping in the hot tub, leaving the tub in a mess. It is essential to shock the hot tub frequently – at least once every week.
Place one tablet in the skimmer basket per 45.450 litres (10,000 gallons) and adjust tablet numbers as necessary to take account of your water flow to achieve 1 - 3 mg/I (ppm) relatively consistently.
A floater is really the worst way to take care of sanitizing your tub—about the most “dinosaur” method still used. It's difficult to regulate the amount of sanitizer being dissolved into the body of water. Then, it starts to seek out what it wants to “eat” after bacteria is gone: pH, tub shell, and more.
for every 200 gallons in hot tub capacity, this means a 220-gallon tub should get about 1.1 oz. of granules, and a 400-gallon one should get 2 oz. As a rough guide, you might expect a couple of tablespoons per dose.
In a clean, freshly filled 500 gallon wading pool, add a quarter cup of unscented household liquid chlorine bleach to the water. Then, at the end of each day, test the water and add an additional 1/8 to 1/4 cup, depending on the reading.
If you are struggling to keep your chlorine levels from dropping, it's important to make sure pH and total alkalinity are in proper range. Also, check your filter. It should be rinsed every 30 days but if you have been using your hot tub more than usual, it might need to be cleaned sooner.
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.
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.
Add the Tablets to the Chlorine Dispenser
The dispenser allows you to adjust how much chemical is released into the water at any given time. This may depend on how often people are using the hot tub or pool.
To use the right number of tablets, always round your pool volume up to the nearest unit of 5,000 gallons. For instance, your pool has a capacity of 20,000 gallons, you would add four chlorine tablets. But if your pool holds just 16,000 gallons, you'd still use four, three-inch chlorine tablets. It's that easy.
Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock.
Is Spa Shock the same as Chlorine? Sodium dichlor shock is a form of chlorine and can act as both sanitiser and shock treatment. If you're using a chlorine-free shock product like MPS (potassium peroxy-monosulphate), then this will not have any chlorine in it.
