You should check your pool water weekly to ensure that all levels are balanced, and that there is sufficient amount of sanitizer (typically free chlorine) in the water.
The basic tests that a homeowner should be capable of doing are for free chlorine, PH, and total alkalinity. PH level should be maintained between 7.4 -7.6. Total alkalinity levels should be maintained between 120-150ppm. Free chlorine levels should stay around a 3ppm.
We recommend all pool owners invest in a simple liquid drop test kit for PH and alkalinity, as well as test strips for the free chlorine. The chlorine test that comes with a standard liquid drop test kit only tests combined chlorine levels, and not the free chlorine levels that are shown by the strips. (Free chlorine is the amount of chlorine in the water that is available to sanitize)
There are numerous other tests that our technicians utilize (phosphate, nitrate, salt, calcium hardness, TDS, etc.) in order to fine tune your water and keep your pool looking great all summer. As always, Humble Lawn & Pool is more than happy to help you maintain the chemical balance of your pool, or handle any other areas of maintenance or service.
