Frequently Asked Questions
Q. Why is my pool water cloudy?
A. The key to clean clear sanitary pool water is always a matter of two things being in balance - chemistry and filtration. Every pool is different because of a number of variables – pool size, bather load, surrounding landscaping, filter equipment efficiency, weather, etc. Although it may seem to be an easy matter to balance the pool chemistry and run the filter equipment, if your pool water is cloudy there is something that is not in balance. At this point it is a matter of deeper investigation to identify the problem.
Q. Why does the “yellow algae” in my pool always come back?
A. Yellow algae, also called mustard algae is a very stubborn strain of algae. Yellow algae are resistant to the sanitizing properties of chlorine. To kill yellow algae, use an algaecide that is specifically formulated to kill it. Then continue to use a preventative algaecide weekly during the spring and summer months.
Q. What should my filter pressure be?
A. Ideal filter pressure can be within a range of 3 to 10 PSI on the filter pressure gauge. This usually provides the most efficient filtration. Filter pressures can vary widely. The more important question is “what is your filters pressure when it is clean”? After you have disassembled and cleaned the filter, what is the starting pressure? Your filter pressure should always be as close to that number as possible. As the pressure begins to rise the filter is collecting dirt. By periodic backwashing or cleaning you can maintain the filters starting pressure.
Q. Can I drain my pool and leave it empty?
A. This is not a good idea. The pools plaster surface needs to be in a chemically balanced environment to maintain its integrity. Also fluctuations in the weather can contribute to the plasters deterioration. A pool that is left empty (without water) for an extended period of time will usually result in damage to the plaster.
Q. How often should I change my pool water?
A. Ask five pool service professionals this question and you are likely to get five different answers – this is my answer. There is no need to change the pool water unless there is a specific problem that requires it. There are a number of problems that would call for draining the pool water, but I do not recommend changing the pool water simply because it has not been changed for a long time. If there is no problem don’t waste your time, money and water.
Q. Will a 2 horsepower pump use less electricity than a 1 horsepower pump because it will circulate more water in a shorter time?
A. Absolutely not! For optimum filtration and energy efficiency most residential pool pumps should be 1/3 to ¾ horsepower. The days of cheap electricity and "bigger is better", are gone
. Properly sizing the pool pump for your particular pool is one of the most cost effective decisions you will make. According to Southern California Edison, the two largest users of electricity in your home is first- the air conditioner and second – the pool filter equipment.
