Swimming Pools

Safe hydrogen sulfide levels are typically not detectable in chlorine swimming pools. If hydrogen sulfide is present, it may indicate an underlying issue such as the presence of sulfur-reducing bacteria or poor water quality. It's important to address the source of hydrogen sulfide and maintain proper pool maintenance to ensure a safe swimming environment.

Solar panels produce DC voltages. I presume that your pool pump uses 120 volts AC. Find the amperage of the pump. Find out what the output current of a single solar cell produces. Divide this into the pump amperage. If the output voltage is 12 VDC then you will need at least 10 cells to start. The total current of these 10 cells will have to be greater that the pump motor nameplate. Now you will have to purchase an inverter to change the DC to AC.

If the solvent pool in a TLC developing jar is too deep, it can cause the sample spots to become diffused or spread out. This can lead to poor resolution and overlapping of the compounds being separated on the TLC plate. It may also make it difficult to accurately analyze and interpret the results.

A normal 20,000 gallon will require 2 1/2 lbs. of Sodium Bicarb. (40 oz.) to raise the pH about .1ppm. So for a 125,000 gallon pool you would use about 240 oz. of Bicarb., or about 14 lbs. I know soda ash is a bit more effective, but this sould give you a good starting point.

Remember to work your way up, not down. It's easier to add chemicals than take them away.

You should be running your pH between 7.6-7.8, not 7.2. It's too low, you'll use too much acid to keep it there, and the index most "pool experts" use is based upon your local water company's index, not an actual swimming pool index.

Yes, you may need to add chemicals to your pool to maintain proper water balance and sanitation. Common pool chemicals include chlorine for disinfection, pH adjusters to balance acidity levels, and algaecides to prevent algae growth. Regular testing and proper chemical treatment help keep your pool water safe and clean for swimming.

Your tests are referring to total alkalinity, not the alkaline nature of something. Total alkalinity (TA) is the amount of pH buffering capability of your water. Low TA allows for pH to change rapidly. High TA on the other hand makes changing pH difficult. Generally speaking, you want your TA to be between 80-120. This allows you to be able to change the pH without difficulty, but prevents pH from "drifting" on its own. Again, generally speaking, pH and TA are lowered together but can be raised separately. Always adjust alkalinity first. If a large amount of adjustment is required, do it over a period of a few days. Then re-test for pH and adjust if required last.

The number of chemical reactions that are possible to cause corrosion are beyond the scope of an internet questions. I do, however, know what is causing the metal to rust. Your "pool chemicals" are likely some acids and bases for pH up or down, a total alkalinity adjuster, and some shock chemicals containing chlorine. Chloride ions in solution are particularly good at being electron sink (a place for electrons to go). In contrast, metal alloys contain various metal atoms with different oxidation potentials that are a great electron source. The presence of chloride, and probably chlorine gas from the bottles, in the same area as metals is the reason for the corrosion. pH up or down chemicals will also cause rust, but most likely the problem is the chlorine. Clean off the metal surfaces and paint them with metal paint or find an alternate place for pool chemical storage.

You need three measurements, length, width, and depth, to calculate the volume of the pool

Due to buoyancy, your body naturally floats in water, making it difficult to stay at the bottom without actively holding yourself down. Additionally, your body may involuntarily float back up towards the surface due to your lung volume and the air trapped inside your body.

On a windy day, the wind causes increased evaporation from the surface of the water in the pool. Evaporation is a cooling process, so as the water evaporates, it takes away heat from the remaining water, causing the overall temperature of the pool to drop. Additionally, the wind can also carry away heat more effectively from the surface of the water, making the pool feel colder.

To increase the chlorine level in a swimming pool, you can add chlorine tablets, liquid chlorine, or granular chlorine according to the manufacturer's instructions based on the pool's size and the current chlorine level. It's important to regularly test the water to ensure the chlorine level is within the recommended range for safe swimming.

To get rid of chemical smells in a swimming pool, you can first check the pH and chlorine levels to ensure they are balanced. Increasing the pool's water circulation and adding activated carbon or a pool deodorizer can help absorb and eliminate the chemical odors. Regular pool maintenance and proper water treatment will also prevent future chemical smells in the pool.

I wouldn't risk it. They wouldn't last long with all the chemicals they put in pools. Turtles are better suited to salt or fresh water.

Yes they can if there are no chemicals. If it is just for housing the turtle. Also if you're keeping it outdoors make sure that it can survive outdoors in your area. Be sure the turtle can climb out of the pool, and be sure Raccoons and other critters cannot get them.

To remove a fireworks stain from the bottom of a vinyl pool liner, first, brush the stained area gently to loosen any debris. Next, create a paste using baking soda and water, then apply it to the stain and let it sit for a few hours before scrubbing with a soft brush. Rinse the area thoroughly with water. If the stain persists, you can try using a commercial vinyl pool liner cleaner following the manufacturer's instructions.

It would be about 32.2 laps to make one mile.

== == Sunlight and environmental pollutants reduce the biocidal effectiveness of the pools disinfection system, while bathers activities add to the potential risk.

One of the side effects of having too much algaecide in a swimming pool includes the likelihood of nose and eye irritations after prolonged swimming. Dry skin is also common after someone has been swimming the whole day and did not lotion up.

The time it takes for alkalinity to clear pool water can vary depending on factors such as the current alkalinity level, the size of the pool, and the effectiveness of the treatment used. In general, it may take a few hours to a few days for the alkalinity levels to adjust and for the pool water to become clear. Regular testing and adjustments will help maintain the proper alkalinity levels in the pool.

To test alkalinity in a pool, you can use a pool water test kit or test strips specifically designed for measuring alkalinity. Follow the instructions on the kit or strips to collect a water sample and add the appropriate reagents. Compare the color change to the provided chart to determine the alkalinity level.

There are two types of salt based pool chlorinators. More expensive and less common are those with a separate salt tank and these will normally use tablet salt for water softeners. The more common type is where salt is added to the swimming pool itself. In the UK we most commonly use PDV salt - that is Pure Dried Vacuum Salt or table salt. Granular salt for water softeners can be used. Tablet salt for water softeners should be avoided unless you have a white liner, because the tablets may bleach spots on the pool liner before dissolving. Julian Hobday of KindWater.

The active ingredient in Baquacil Metal Control is chelating agent. It helps prevent staining and discoloration caused by metals in pool and spa water by binding with the metals and preventing them from reacting with other chemicals.

In water it surely does. It is very dense.

All the water in the pool bend a lot of the light that enters your eyes, so the floor appears closer and bent too. You can look at the bottom of a cup full of water, and the bottom would also look bent and closer.

To have a better view of the actual depth, you can empty out all of the pool's water if there's an electric switch that can do it. Once all the water drains out, you'll know whether it's a good idea to swim in this pool depending on how experienced you are at swimming.

Or, you can fasten a pair of goggles on, lie face-down on the edge of the pool so that only your head and neck and maybe upper-chest are above the water and not touching the ground. Inhale and hold your breath, then bend down so that your protected eyes dip below the water so you can clearly look around the pool and see the bottom. The rest of your body (from chest to feet) should be lying on the ground with your hands clasped onto the edge of the pool, preventing you from falling in. Just to be sure, in case you might fall in somehow, have someone relatively nearby.

Another way to determine the depth is to get a yardstick or a really long stick to lower into the pool until it reaches the bottom, so you can measure the actual depth of the pool.

By the way, never play in a swimming pool by yourself, unless if you're a very experienced swimmer or the pool is deep enough so the water only reaches your chest when you stand up straight in the pool.

The density of water remains constant regardless of the volume or shape of the container it is in. This is because the mass of water and its volume stay the same, resulting in the same density for both a pool and a cup of water.
