Generally, pool water needs to be replaced once every five to seven years. This should be done during mild weather so that your pool surface is not at risk from strong sunlight and heat. Your pool maintenance company can recommend when it is time to drain your pool.
Maintenance is critical when it comes to the quality of your pool water. Well maintained pool water can last up to 5, maybe even seven years before you need to replace it. This means weekly cleaning, functional filters, and checking ph levels every day.
Pool industry experts recommend you drain your pool and refill it every five to seven years. No two pools are alike, so there is no set number at which you must drain your pool.
Draining a pool is risky business for several reasons. Your pool is not meant to be empty. Whether you have a vinyl, concrete, or fiberglass pool, it is at its best when it's full of water. Once the water is drained, you open yourself up to all sorts of damage, so drain a pool only when there is no other option.
Resale Value
A pool can increase not only your social worth but also the value of your home. However, the increase is probably not as much as you think. According to HouseLogic, there's no real guarantee that you'll make your money back. In fact, adding a swimming pool may only increase your home's value by 7%.
I think the answer to your question is about 3-6 days. The problem is that the chlorine that you need to keep the bacteria in check is used up more quickly as the temperature rises, the activity increases, and as sweat and other body stuff is put into the pool.
On average, swimming pools lose about a quarter of an inch of water each day, yet variations in wind intensity, humidity and sunlight can drastically change water loss rates. Some of the strongest and most intense wind in the country can be found in mountainous regions.
You can do the “bucket test” on your pool to measure evaporation. Place a bucket of water beside the pool and mark both the water in the bucket and the pool water level. Wait 24 hours then check the loss of both. If the pool loses more water than the bucket, then you have a leak.
The average pool water evaporation rate is about a quarter of an inch of water per day or more than two inches in a week, which on a 33′ x 18′ swimming pool (an average pool size) is more than 2500 liters or approximately 600 gallons a week; this may vary depending on your climate and the factors listed above.
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. Granular chlorine can be re-packed to extend its shelf life.
Even from a health standpoint, it is simply not safe to operate a pool without some added “chemicals” to combat bacteria and contaminants in the water. A pool without chemicals is the perfect breeding ground for bacteria, viruses, and parasites.
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.
No, you cannot use the liquid dishwashing soap at home to clean your pool.
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
Household bleach, Clorox and liquid chlorine can all be used to sanitize a pool. They are all types of chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine. Household bleaches often have unwanted fragrances and colors.
The Bottom Line
Adding a Magic Eraser sponge to your pool skimmer is not a professional-approved pool maintenance technique. It may remove some algae, but it may also cause other problems you're not anticipating – including serious health risks.

Using vodka gives your pool a deep clean besides disinfecting it. However, a simple answer by pool research experts to the question “does vodka really clean a pool?” is no! This is because vodka would cause a chemical imbalance in your pool, leading to severe issues in the future.
Your pool also loses water in summer, up to 2 inches per week, due to the heat of the air. You can employ a swimming pool cover to protect the pool from these powerful rays. A pool cover will also keep heat in your pool when the weather is cold. In summer, the air around the pool is hotter than the pool water.
If your pool lost water overnight and it is more than the quarter-inch due to evaporation, you probably have a leak. Evaporation accounts for a minor amount of water lost each day. Losing a half-inch or more overnight indicates a problem.
