Pool water testing - no pool problems
At least once a week, the swimming pool water needs to be tested to ensure certain levels of pool chemicals. This is most conveniently done after backwashing the filter.
A good pool test kit is a must - preferably one that uses tablets rather than liquid drops. Expired tablets/ test liquids (reagents) should be thrown out as they very often give inaccurate readings, resulting in us pouring unnecessary (expensive) chemicals into our swimming pools. Always keep the test kit in a cool dry place out of the sun and out of the reach of children.
When testing the pool water, rinse the cells of your test kit thoroughly before filling them with water from at least 20-30 cm below the surface of the swimming pool. When you're finished the tests, never empty the test solution back into the swimming pool.
If there are no obvious problems in your swimming pool, the following tests need only be done every 3 months or so but preferably every month. They are either undertaken by a professional swimming pool consultant who comes to your pool, or they can be done at many specialist pool shops if you take them a pool water sample (in a clean glass jar!).
If the water in your area is free from any metals and your swimming pool shows none of the symptoms of iron or copper presence, the test for these metals is unnecessary. If, however, you notice staining on the walls and floor of the swimming pool, you should have the levels of these metals checked.
