Chlorine Granules are a powder form of chlorine (Sodium Dichlor) and they can be added directly to your hot tub water. Chlorine Tablets for hot tubs (Trichlor) are the size of a 50p piece and usually float in a dispenser or an in-line feeder.
Which is better liquid chlorine or granules?
Liquid chlorine is generally less costly than granular shock and comes in refillable containers, where granular shock does not. Liquid chlorine does not need to dissolve in your water as it is already in liquid form. In addition, liquid chlorine is non-scaling and leaves no residue.
How long do chlorine granules take to work?
Typically, a 3-inch pool chlorine tablet is designed to chlorinate from 7,500 to 10,000 gallons of water per week, meaning it’ll take seven days to dissolve.
How long do chlorine granules last?
Granular chlorine when kept in airtight containers that are cool and dry can last for over five years, though when stored otherwise and exposed to humidity it can dissolve in under two years.

How often do you add chlorine granules to pool?
Shock is liquid or granular chlorine. You should add one gallon (or one pound) of shock per 10,000 gallons of pool water every week to two weeks. During hot weather or frequent use, you may need to shock more frequently.

Can I put bleach in my pool?
Clorox itself recommends using between 100 and 200 ounces of regular-strength bleach per 10,000 gallons of pool water — one gallon is 128 ounces, and many bottles of bleach are available in one-gallon or half-gallon sizes. Pool professionals tend to recommend more conservative amounts of bleach.
How long after shock can I add chlorine?
You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool. As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.

Does granular chlorine raise pH?
Liquid chlorine and bleach (sodium hypochlorite) have a pH of 11.0 to nearly 13.0 so it is logical to think that they will raise the pH of the pool water. The fact is that initially or upon addition liquid chlorine raises pH because sodium hydroxide (lye) is made.
Can you mix liquid and granular chlorine?
It is best to wait before going into the pool because liquid chlorine levels will be high after shocking, but it will be safe to swim after only 24 hours. Each chlorine compound is designed for a specific purpose. Using these two types in conjunction with one another will keep your pool clean, clear and sparkling!
Are chlorine tablets or granules better?
The Advantage of Chlorine Tablets for Swimming Pools
The most significant benefit of using chlorine tablets for your pool is its longer-term nature compared to granules. Once you get the right dosage, you shouldn’t have to add another chlorine treatment for at least a few days.
Do chlorine granules dissolve in cold water?
The cold water, anything below 65°, has an impact on the ability of the chemicals to dissolve properly. I would recommend using liquid chlorine if you have to shock in lower temperatures. You can dissolve granular shock in warm water. Perhaps it will work if you completely dissolve it before adding it to the pool.
Why are my chlorine granules not dissolving?
Because stabilizer granules are slow to dissolve, certain manufacturers recommend dissolving cyanuric acid in warm water before adding it to the pool. Others recommend broadcasting the granules over the pool by adding the product near a jet or return line.
