Some indicator solutions sold specifically for pools already contain a chlorine neutralizer to combat this bleaching action. The number of tablets required to bring about this change is recorded and multiplied by a constant provided by the test-kit manufacturer.

For more on water hardness, see the section on Keeping Your Water Balanced. Like total alkalinity, an end-point reaction best measures calcium hardness. The first reagent is a pH buffer to bring the pH level up to approximately The second step adds a dye that, when reacting with calcium, turns the sample water a different color.

Next, the titrant EDTA is added one drop at a time until the water changes color. The total number of drops required gives you the amount of hardness when compared with a manufacturer's chart. Using Palintest Calcium Hardness tablets, add one tablet at a time shaking the bottle until dissolved. Keep adding tablets until the color changes from pink to bright violet.

However, more accurate measurements can be made by using a test kit designed specifically to determine calcium hardness and by following the manufacturer's directions regarding color changes. In these tests, a specific amount of water is taken from the pool, and an indicator is added to the sample. A reagent is added, causing a color change that indicates the calcium hardness level in ppm. To test for total hardness, an exact amount of pool water usually 60 ml is treated with a solution called a buffer.

Then a dye is added. The reagent is added to the sample and mixed, one drop at a time. The number of drops necessary to change the water color, multiplied by a constant provided by the manufacturer, determines the hardness in ppm. The tablet method for testing water hardness is equally simple. A tablet containing the pH buffer, the indicator dye, and the hardness reagent is added to a ml sample of water. The color changes as additional tablets are added.

The number of tablets required to bring about this change is recorded and multiplied by a constant provided by the test-kit manufacturer. Total dissolved solids TDS is the measurement of all materials dissolved in the water, i. TDS is measured by using a portable electronic analyzer. The equipment is specifically used to measure for dissolved solids and should be standard equipment for operation of spas and hot-water pools.

A pool should be dumped and refilled when a TDS reading exceeds 1, ppm above the domestic water supply reading. This equipment is quite expensive and is not normally at the disposal of the private pool owner, so you have two choices: Take your sample of pool water to your pool center and ask them to measure TDS for you. They will normally be happy to do this for you free of charge if you usually buy your chemicals etc from them. As TDS plays a less important part in the calculation than the other factors you can estimate it, but do bear in mind that this will then only give you a rough idea of whether the water is scale forming or corrosive.

As a guide, for pools which have been recently refilled, use a figure of ppm. For pools which have not been recently refilled, or where there has been little water replacement by backwashing, or where cyanuric acid levels are above ppm, use a figure of ppm for TDS. Super Chlorination or Shocking Super chlorination is a term that describes an extra large dose usually 8 to 10 ppm of chlorine to oxidize organic compounds and kill and remove algae and other contaminants from the water.

This is the same as using three to six times the normal dosage of a chlorinating agent. As mentioned, HOCI is the form of chlorine that provides sanitation. Because it is an extremely active chemical, however, it also reacts with organic impurities. When there is enough HOCI present, the impurities are completely oxidized. Combined chlorine is formed when there is an insufficient supply of HOCI or when there is a very high level of organic impurities.

Combined chlorine compounds can be oxidized by increasing the HOCI level in the water. The point at which all the organic impurities are oxidized is called the breakpoint. The addition of sufficient chlorine to reach this point is known as breakpoint chlorination. Every once in a while, your pool or spa water may become a veritable hotel of unwelcome contaminants and bather waste products. You can often detect when this happens because a "chlorine" odor may begin emanating from your pool or spa, or you may notice that you're experiencing some skin and eye irritation.

But the most reliable -- and better -- way to monitor your water quality is to take a second look at your sanitizer readings. If your chlorine test readings keep dropping hard and fast, you may be faced with the need to evict chloramines from the water. For more on how chloramines form, see the section on Keeping Your Water Balanced.

This is done easily enough with a process called shocking. No, you don't electrocute the chloramines. What this process entails is adding extra high doses of sanitizers to the water. By adding a large dose of chlorine -- a process called super chlorination or shocking -- you bring up your residual of free available sanitizer in a relatively short period of time.

The newly added sanitizer will promptly rid your pool and spa water of those annoying guests. To be safe, do not use your pool or spa for at least 24 hours after shocking with chlorine. You should also test for the proper sanitizer levels before getting back in the water. There are non chlorine shocking products available that lessen the amount of time swimmers need to stay out of the pool or spa. Add large amounts gradually in thirds over a 2-hour period.

Add directly into the pool or spa when no swimmers are present and time is sufficient to permit even distribution of the chemicals. Add indirectly in small amounts slowly through skimmer or overflow to prevent corrosion of metals.

Heat consumes chlorine, and makes it easier for algae to grow, who prefer the warm water. Pool, can I ask you a few questions? Everyone has this idea pop into their head first, but can you really lower pool water temperature with ice?

I pressed him for a formula for determining how much ice would be needed to lower pool water temperature, so he scratched this out on a slip of paper. For example, cooling my gallon pool down 10 degrees Fahrenheit would look like this: Great for adding a spooky fog on the surface of the pool, but not so good for lowering pool water temperature.

He also warned that it will pummel your pH level, being very acidic, and could cause skin burns if swimmers touch it. We want to hear from you!
