Chlorine tablets are slow dissolving and therefore need to be placed in either a floating dispenser, in-line chlorine feeder or a skimmer basket.
U.S. Pool Supply Floating Chlorine Dispenser
Highly reviewed, users found that the dispenser held up and did its job no matter how rough and tumble kids and pool users were with it. Easy to load and adjust for chemical output, this dispenser does the job of keeping the pool water clean and sanitized quietly and simply.
To use this Spa & Hot Tub chemicals dispenser, simply remove the top and place the slow dissolving chlorine tablets or bromine tablets in the base of the Spa & Hot Tub chemicals dispenser. Replace the lid and place the Spa & Hot Tub chemicals dispenser in your Spa or Hot Tub.
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.
Floating pool dispensers can be used in aboveground and inground pools, but make sure your pool manufacturer says it's safe to use one. The chlorine floater must be removed from the water when people are in the 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.
Answer: Yes, when using tablets they can be present in the water while you swim. Also confirm with a test of the chlorine level to be sure the sanitizer level is safe for swimming.
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.
You should put chlorine in your hot tub at least once a week. However, some people prefer to add a small amount after each use. Finding the best water care routine will depend on how often and how many people use it. Chlorine levels should be between 1.5 and 3.0 ppm.
Facts about water buoyancy
On thin surfaces, humans and objects float easier. That's why they float in salt water rather than fresh water. The lower the salt level in swimming pools, hot tubs, lakes and rivers, the higher the boom. The bones and muscles are denser than fat and will not float.
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.
It is recommended to wait at least 20 minutes to an hour after adding water balancing chemicals. You should wait 2-4 hours (or one full cycle through the filter) to swim from the moment you use calcium chloride in your pool. It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours.
If you have a spa, bromine has a lot of advantages over using chlorine. It may cost a little bit more, but it lasts longer and does a much better job than chlorine at killing bacteria, especially at high temperatures and high pH levels.
In theory, if you have a cloudy swimming pool, you can add chlorine to “shock it” and clear things up. Chlorine will get the job done. But, the amounts may vary and you may have to really pound the pool with chlorine to get the water totally clear.
Chlorine in general is an excellent controller of bacteria. It works quickly and effectively to keep your hot tub safe! Both chlorine tablets and chlorine granules are therefore very effective in killing bacteria. The key comment to make here is that all hot tub users must ensure their chlorine level is between 3-5ppm.
Dichlor, short for Dichloro-S- Triazinetrione, is one type of chlorine available for keeping pool water clean. Similar to trichlor, a different kind of chlorine, dichlor is usually granular but can also be found in tablets.
A typical use of one person taking a 15-minute soak once a week might only require adding chlorine every 2-3 days, while more frequent use can mean topping up the chlorine every day. Another factor that contributes to how often you need to add chlorine is the total amount of bathers in your hot tub at one time.
If theres too much chlorine it will vaporise and form gas that floats just above the surface of the water. If this vapor is inhaled it can inflame airways and exacerbate certain breathing conditions. Read more What Temperature Should My Spa Pool be at and Why?
A chlorine level of between 3-5mg/l must be maintained in your hot tub at all times. The addition of chlorine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 1mg/l add 2g per 1000 litres).
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.
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.
When a pH is too high in a hot tub, the water becomes scale forming . High pH can cause premature equipment failure and increase your sanitizer consumption.
Do NOT use chlorine granules in a floater or feeder. When you're adding granules, broadcast them evenly over a wide area in the deepest part of the pool – NOT in the skimmer.
If the tablets are not dissolving, and you get a strong smell of chlorine when you open the chlorinator, you probably have a bad check valve in the chlorinator. It is not allowing any water to move through the chlorinator, and any water that is there simply sits there and builds up a yellowish chlorine gas.
As a general rule, we see stabilized chlorine tablets (also called trichlor tablets) last anywhere from two to three days. Slow dissolve cal-hypo tabs may last four to five days.
