Preguntas frecuentes sobre Water analysis
Why is it important to analyze pool water?
Analyzing pool water makes it possible to determine the water’s actual condition before adding chemicals or modifying the treatment.
Measuring parameters such as pH and disinfectant levels helps detect deviations and make the necessary corrections. Depending on the treatment system and the water’s characteristics, it may also be advisable to monitor alkalinity, hardness, stabilizer, salt, or other parameters.
Analyzing the water before dosing prevents treatments from being carried out based solely on the water’s appearance, smell, or color.
What parameters should I analyze in pool water?
The parameters that need to be monitored depend on the type of pool and treatment system.
pH and disinfectant concentration are among the usual measurements. In certain installations, it may also be necessary to monitor alkalinity, calcium hardness, cyanuric acid, salt, bromine, or other parameters.
Not all kits, strips, meters, or photometers analyze the same parameters, so it is advisable to check which measurements you need before choosing an analysis system.
How often should I analyze my pool water?
There is no single frequency that applies to all pools.
The testing frequency depends on factors such as the type of treatment, water temperature, number of swimmers, weather conditions, and parameter stability.
During the swimming season, regular checks are advisable, with increased frequency when water conditions change, after an incident, or before and after certain chemical adjustments.
What values should pool water have?
The appropriate values depend on the treatment system, type of pool, and applicable recommendations.
For chlorine-treated pools, an approximate pH of 7.2 to 7.6 is commonly used as a reference, but it is not advisable to establish a single universal table for pH, chlorine, bromine, alkalinity, hardness, stabilizer, or salt.
To interpret an analysis correctly, use the ranges corresponding to your treatment system and the instructions for the products and equipment installed.
What is the difference between strips, reagent kits, and pool photometers?
Test strips allow quick checks of different parameters. Reagent kits use a chemical reaction that must then be interpreted according to the system used.
Pool photometers perform an instrumental reading of the reaction produced by the reagents and can facilitate a more objective measurement of certain parameters.
This does not mean that every photometer automatically provides exact results. The quality of the equipment and reagents, storage, calibration where applicable, and correct performance of the test all affect the result.
Which water analysis system should I buy for my pool?
The choice mainly depends on the parameters you need to measure and the level of monitoring you want to perform.
For basic checks, certain test kits or reagent strips may be sufficient, while a photometer may be useful when you want to measure several parameters with a digital reading or perform more comprehensive checks.
Before buying, check which parameters it measures, the measurement range, the reagents required, how easy it is to obtain replacements, and the operating procedure.
What is the purpose of measuring pool water conductivity?
Water’s electrical conductivity is related to the presence of dissolved ionic substances, including salts, but it should not automatically be interpreted as a specific measurement of sodium chloride.
In saltwater pools, it is important to know the salt concentration required for the chlorinator to operate within the range specified by its manufacturer.
To monitor salinity, use equipment or a method suitable for this measurement and check that the result is expressed and interpreted correctly for your salt chlorinator.
What should I do if my pool water analysis result is out of range?
First, confirm the measurement and determine which parameter needs correction. It is not advisable to add several chemicals at once in an attempt to solve the problem without knowing its cause.
Make adjustments according to the instructions for the product used, taking into account the water volume and initial value, and measure again when appropriate to check the result.
If several parameters are unbalanced, it is also important to bear in mind that they may be related to one another and that the order of correction may depend on the treatment used.
