Hello to everyone.We have been maintaining swimming pools in Serbia for 20 years and we have never had a problem with alkalinity in the water, we never even measured.
A year ago, in one of the pools where we disinfect the water by electrolysis system, we noticed problems with the alkalinity dropping incredibly quickly, which created a problem with the chlorine measurement probe.
The pool is filled with city water where the alkalinity is around 200 and in a few days it drops below 30. At that time, the chlorine probes were not working. We tried adding baking soda, but we had to add it in large quantities to keep the alkalinity range between 80 and 120.
This was not a solution because using so much baking soda caused the water to change color and form a precipitate.
Does anyone have experience telling us why the alkalinity in the pool drops so quickly and how to solve the problem so we can measure the chlorine residual in the pool since the pool is not private but public and we have to measure the residual?
