# Can a saltwater pool freeze?

Yes, a saltwater pool can freeze in cold temperatures just like a traditional freshwater pool. It's important to take precautions to prevent freezing, such as running the filtration system continuously and using a pool cover.

# Can you get struck by lightning in a hot tub that is on a deck?

Yes, it is possible to get struck by lightning in a hot tub that is on a deck. Water is a good conductor of electricity, so if lightning strikes the hot tub or the deck, the electricity could travel through the water and potentially harm anyone inside the hot tub. It is important to follow safety guidelines during thunderstorms and avoid being in a hot tub during lightning storms.

# How are geothermal pools formed?

Geothermal pools are formed when hot water from beneath the Earth's surface rises to the surface, carrying with it minerals and gases. This hot water then collects in depressions or cavities on the Earth's surface, creating geothermal pools. The heat from the Earth's interior warms the water in these pools, creating the relaxing hot springs that people enjoy for relaxation and health benefits.

# How one might use bromthymol blue and phenolphthalein to test the ph of water in a swimming pool?

To test the pH of water in a swimming pool using bromthymol blue, add a few drops of the indicator to a water sample. The color change will indicate the pH level. Phenolphthalein can be used similarly; a color change to pink indicates the presence of a base (high pH). Compare the color changes obtained from both indicators to assess the pH level accurately.

# How many cubic meters of water in a swimming pool that is 24 feet round and 5 feet deep?

The swimming pool has a diameter of 24 feet, which means a radius of 12 feet. Using the formula for the volume of a cylinder (V = πr^2h), with a depth of 5 feet, the pool would contain approximately 33.5 cubic meters of water.

# After backwashing a pool do you need to add earth back to the filter immediately?

Yes, after backwashing a pool filter you should add diatomaceous earth (DE) back to the filter immediately if you have a DE filter. If you have a sand or cartridge filter, there is no need to add anything after backwashing.

# Can lightning strike you in a swimming pool?

Insurance companies seem to think it's likely, but that's not saying a whole lot. I swim in an indoor pool that is in the LOWER level of an athletic center, and when the front desk hears thunder . . . out we go for 30 minutes! Stupid.

I have done extensive research on the web to find an answer to the question of getting hit by lightning while swimming. In more than 450 cases I have looked at I have found only two in which one person, who was among others swimming in the ocean, was struck by lightning, and the other was a scuba diver, and the lightning actually struck his tank while he was coming out of the water. The first guy was surfing, so you might even say he was not technically in the water, but on it (perhaps making him more of a target?).

I have also found that while people do not seem to be struck by lightning in the water, many, many are struck just after getting out of the water to take shelter. I've yet to find one in which people are struck by lightning in a swimming pool--recently or any time in the "ignorant" past when people "didn't know better" to get out of the water when thunder was heard.

The whole idea of a pool-full of people being killed or electrocuted from a single strike in the water is ridiculous. I know it sounds right, though, since water is a good conductor of electricity. I have even read some pretty stupid remarks by "experts" that claim when lightning hits the water it disperses throughout the entire body of water. But this is simply not true, and research shows it not to be the case (hey, where are the thousands of dead fish that should wash up on shore after a stormy afternoon at the beach?). No "expert" can actually tell the truth about this because it is "conventional knowledge" that you are not to be in the water when thunder is heard--and insurance companies wouldn't like it.

How about this one: I found one story in which a man was killed by a lightning strike while sitting in his boat (a common place for people to get struck) while his two friends, who were swimming next to the boat, looked on, completely unharmed!

Most people who are struck were hit while standing out in the open, wet with rain, not under cover. And what happens when you get out of a pool? Hmmm, suddenly you are a lightning target standing in the open!

I've found many stories of people getting struck on a clear day, in their homes, in cars, laying on the ground, under trees, standing next to swimming pools--in short, all the places you are advised to go to take shelter. And only two of people being struck in the water (ocean, to be specific). There are probably more out there, but good luck trying to find them.

Perhaps, if proper research was conducted, it might actually turn out that we should all be diving into water when we hear thunder!

# How many kw of electricity should a 1 hp pump use in 24 hours?

A 1 HP pump typically consumes around 0.75 kW of electricity. In 24 hours, this pump would use approximately 18 kWh (0.75 kW x 24 hours = 18 kWh) of electricity.

# Can using to many extension cord reduce the pressure on the pool pump?

Using too many extension cords can lead to a drop in voltage, causing the pool pump to work less efficiently. This reduction in voltage can reduce the pressure at which the pump operates and may lead to potential damage or overheating of the pump motor. It is best to minimize the use of extension cords and ensure that they are of adequate length and gauge for the equipment being powered.

# How many gallons of water does a pool 10'x15'x52inches hold?

A pool measuring 10'x15'x52" holds approximately 3,944 gallons of water.

# Can you swim during a lighting storm in an inside pool?

Swimming during a lightning storm in an indoor pool is generally considered safe because indoor pools are grounded and protected from lightning strikes. However, it's always best to err on the side of caution and avoid swimming during a storm to minimize any potential risks.

# How do I know the amount of swimming pool chemicals I need for my home swimming pool?

You can determine the amount of swimming pool chemicals needed based on the volume of your pool. Your pool supplier or a professional pool maintenance service can help you with this calculation. It is important to follow the manufacturer's instructions for the specific chemicals you are using to ensure they are properly balanced.

# If you want to measure the amount of water that can fill a swimming pool what standard unit of measurement would you use?

Liters or cubic meters are typically used to measure the volume of water in a swimming pool.

# How does adding food coloring to water affect its evaporation?

Adding food coloring to water will not affect the water's rate of evaporation. The food coloring simply changes the color of the water but does not alter the basic properties of the water molecules that determine its evaporation rate.

# What causes discomfort in the midddle ear when diving to the bottom of a deep pool?

When diving to the bottom of a deep pool, the increase in water pressure compresses the air inside the middle ear. This pressure differential can cause discomfort or pain due to the unequal pressure on both sides of the eardrum. Techniques such as equalizing pressure through methods like swallowing, yawning, or pinching the nose and blowing gently can help alleviate this discomfort.

# Describe what is meant by specific heat Which has the highest specific heat the grass the parking lot or the swimming pool?

Specific heat is the amount of heat energy required to raise the temperature of a substance by 1 degree Celsius. The swimming pool would have the highest specific heat because it can absorb more heat energy compared to grass or a parking lot due to its larger mass and ability to retain heat.

# A swimming-pool worker wants the pool's pH to be 7.2. She comes by to test the water and finds that the pH is 9.2. What should she do to correct this situation?

To lower the pH from 9.2 to 7.2, the worker should add an acid, such as muriatic acid or pH decreaser, to the pool water. She should follow the manufacturer's instructions on the product to gradually lower the pH level, frequently testing the water until it reaches the desired pH of 7.2.

# Why is it important to understand the chemical composition of chlorinating agents used in swimming pools before using them?

Understanding the chemical composition of chlorinating agents is important to ensure proper disinfection of the pool water. Different chlorinating agents have varying strengths and properties, and using the wrong type or amount can lead to ineffective sanitation or even harmful chemical imbalances in the water. It is crucial for maintaining a safe and hygienic swimming environment for users.

# John is trying to drain a swimming pool. He has two pumps but he can only use one at a time. He knows that the time a pump takes to drain the pool varies inversely with the power in watts of the pump.?

If the time it takes to drain the pool varies inversely with the power of the pump, it means that as the power of the pump increases, the time it takes to drain the pool decreases. Therefore, John should use the pump with the higher power to drain the pool in the shortest amount of time.

# What to do when pool cover has heavy snow and ice?

It's best to remove the snow and ice from the pool cover to prevent damage and ensure proper functioning. Use a broom or soft snow rake to gently push off the snow. Avoid using sharp tools or excessive force to prevent tearing the cover. If the ice is too difficult to remove, applying a de-icer or warm water can help melt it.

# How and how much pH minus do you use when alkalinity is 350 in a 6800 gallion pool?

To lower pH in a 6800-gallon pool with an alkalinity of 350 ppm, you would typically use pH minus according to the product's instructions. The amount needed can vary based on the product concentration and pool conditions, so it's best to follow the manufacturer's guidelines for dosage. It's important to test the pH after adding the pH minus and make adjustments as needed to reach the desired range of 7.2-7.6.

# How long to wait after adding clarifier to pool to add other chemicals?

It is generally recommended to wait at least 24 hours after adding a pool clarifier before adding other chemicals to allow the clarifier to work effectively. This will ensure that the clarifier has sufficient time to settle and improve water clarity before introducing additional chemicals.

# Why is it important to understand the chemical composition of chlorinating agents used swimming pools before using them?

Because each different type of chlorine will effect your pH differently. Each type of chlorine also leaves behind different ingredient residuals. For example.. Liquid chlorine leaves behind some salt, tablets leave behind chlorine stabilizer, some shock bags leave behind calcium and other shock bags leave behind chlorine stabilizer. There are many other types... Also, do not ever mix them together. The results could be chemically life threatening and explosive. Bottom line....read the label and really know what you are buying.
