Liquid Chlorine has the shortest shelf life of all your pool chemicals, losing up to 50% or half of its potency six months from when it was first opened and up to 90% after a year.
Most pool chemicals have a shelf life of 3-5 years, when stored properly: Consistent and cool temperatures, in a dry and dark location. Tight bucket lids and bottle caps, and sealed inner bags to lock out moisture and contaminants.
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.
So if you buy liquid shock, be aware that it only lasts one to two months at the most before it starts to lose effectiveness. While many swimming pool chemicals stay good for years if stored correctly, some pool-maintenance supplies expire more quickly.
The simple answer to this question is yes. Like any chemicals, chlorine tablets go bad if left long enough or improperly stored. Kept in the right conditions, however, and they can remain effective for over five years.
Liquids should not be stored on top of solids. Acids and chlorine should be stored apart from each other. Chemicals should be stored far away from electrical sources and heat, and areas prone to flooding.
Store them in separate containers with lids in a locked shed away from the house and pool." The State Fire Marshal wants homeowners to ensure their pool chemicals are being stored safely, as any moisture or container left opened could pose serious health risks.
All pool chemicals, aside from unstabilised liquid chlorine, are good for up to three to five years as long as they're stored in a cool and dark place away from sunlight and they're packed in air-tight containers.
There is no harm in using liquid chlorine after storing it through the winter, but it will be less effective than when initially purchased. Pool chlorine comes in different forms with differing levels of stability.
Can Pool Chemicals Be Stored Outside? If you live in an area where the temperature is moderate, without extremes of heat or cold, then it's fine to store pool chemicals outside. However, if your climate is subject to extremes, indoor storage may be preferable to prevent chemicals from reacting to heat or freezing.
Liquid chlorine — In general, it's a good idea to wait at least four hours after putting liquid chlorine in the pool. The size of your pool and the amount of chlorine added does play a factor in this, too. Once your levels reach 5 ppm or lower, you're ready to swim.
Powdered chlorine is the most typical form of chlorine used in a domestic pool environment. It is typically only slightly more expensive than liquid chlorine but it is much easier to use and has a lower pH, therefore has less impact on your pool's balance when used.
Liquid chlorine
They are identical in every way, with the exception of strength. Household bleach is usually a 6% concentration (although some of the cheaper stuff is 3%), while pool chlorine can typically be found in strength between 10% and 12%.
Are chlorine and shock the same thing? SKIMMER NOTES: No. Chlorine and shock are not the same thing. Shock has a more intense chemical strength than the traditional chlorine sanitizers, and it also differs in how you should apply it to your swimming pool.
The first thing to note is that it is recommended that you keep your pool chemicals at a location no warmer than 95º. The pool chemicals are reactive to sunlight so the chemicals should never be stored in direct sunlight or be near any type of heat source.
As long as the climate you live in doesn't get extremely hot in the summer, storing pool chemicals outdoors is a possibility. Just make sure they're protected from the elements including direct sunlight.
Your pool chemicals should always be stored in a cool and dry environment, to prevent them from becoming defective or dangerous. Typically, pool owners will stash their chemicals in an outdoor shed or garage.
Answer: It is true that pool chlorine is stronger than bleach. For bleach and water to be the same strength as pool chlorine and water, you would have to adjust the ratio, increasing the bleach and reducing the water. But no matter which chlorine you use, make sure to test a small area before doing the job.
Pool-grade chlorine and a jug of Clorox are essentially the same thing, chemically. However, they're not made with the same concentrations of chlorine. Pool-grade chlorine, which you can usually buy in tablets, granules, or as a liquid, tends to be available in formulations of between 65% and nearly 100% chlorine.
Liquid chlorine may be a good choice if you have a large pool, but the costs associated with it, and the available chlorine per pound could mean that chlorine granules are the better option. In the end, both liquid chlorine and chlorine granules will do their job and keep your pool clean and clear.
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.
Liquid chlorine is basic or alkaline (high pH) and requires a conscientious effort for safe handling and storage. Although powder or granular packages offer greater convenience, they still require attention for transportation, storage and usage. Total alkalinity is the measure of water's resistance to change pH.
Liquid Chlorine: Depending on how much you have added and the size of your pool, it is generally safe to wait about 4 hours after adding liquid chlorine or until levels reach 5 ppm or lower. After Shocking Your Pool: It is safe to swim once your chlorine levels reach 5 ppm or lower, preferably at 3 ppm.
