What is the purpose of acid washing?

An acid wash will generally remove superficial stains, fine scale deposits, and various colored deposits from the plaster. The process strips off (dissolves) a very thin layer of plaster, and will therefore generally restore 70 to 80 percent of the plaster’s brightness. An acid wash will not remove heavy deposits or stains that have penetrated through many layers of plaster. Acid washing is the most practical means of removing unsightly stains and an acid wash is absolutely essential to successful pool painting. If the pool is to be painted, the surface must be thoroughly etched with acid prior to applying paint.

Prior to draining the pool for an acid wash, the pool must be free of algae and debris (it will clog the pump). As a rule, acid washing a pool should be done by a licensed professional.

Why do I need to shock my pool?

When sweat, urine and other swimmer wastes enter the pool water, they quickly react with the chlorine to produce Combined Available Chlorine, also known as chloramines. This Combined Available Chlorine is much less effective than Free Available Chlorine. It usually has a foul smell and is an eye and skin irritant. Shocking will free up the Combined Available Chlorine up and return it back to the water as Free Available Chlorine.

How long should I wait after shocking my pool to be able to swim?

This depends on what you are using to shock your pool. If you are superchlorinating with a chlorine product such as a powdered shock that has 65% or more available chlorine we recommend that you wait and stay out of the pool until the chlorine level drops to 2.0-4.0 ppm. In some pools it could be up to 8 hours or 36 hours. It all depends on the chlorine demand of the pool itself. Re-testing the pool water is the only way to know if it is at this safe level to re-enter the pool.

Is it better to use the drops from a test kit or test strips to test my pool water?

Both provide usable results when used properly. Reagents (drops) are more precise, offering results that are as accurate as possible, while test strips display results in more general ranges. However, test strips are generally considered easier to use than the reagents. Since results from both are acceptable, it is simply a personal preference.

How long should I run my pump?

The pump should be run as long as it takes to cycle all the water through the circulation system. This is called Turnover Rate, and it varies from pool to pool based upon the size of the pool, the plumbing, and the pump. A general rule of thumb is to run the pump for 6 to 8 hours.

Can I get sick from algae?

You cannot get sick from the algae itself. However, algae can harbor disease-causing organisms that can cause illness. Algae also makes the pool surface dangerously slippery. Prevention is the best medicine; it is easier to prevent algae than it is to remove it.

My pH keeps dropping. What could be causing the problem?

Are you testing the Total Alkalinity? If not, your Total Alkalinity is probably low. What is Total Alkalinity? In simple terms, it is a key water element that helps keep the pH stable and in the proper range. The ideal range for Total Alkalinity depends on the type of sanitizer used. If you are using trichlor, sodium dichlor or bromine tablets, the range is 100-120 ppm. If you are using calcium hypochlorite, lithium hypochlorite, or sodium hypochlorite, the ideal range is 80-100 ppm. Call a J and M pool professional for more information.
