Our pH is on the lowest end of the test strip. We have added 8 lbs. Of baking soda and it does not seem to have done a thing. What can I do?
It is important to maintain the total alkalinity (which is abbreviated as TA) of the water in your swimming pool in a range of between 80 and 120 PPM, but it is more important to maintain the pH of the water in your swimming pool in the range of between of 7.2 and 7.8. The buffering effect could be higher than the normal limit because the water in your swimming pool probably contains some other minerals than bicarbonates and carbonates.
The pH of the water in your swimming pool can naturally be brought up by the use of minerals without making corrections on a regular basis. The main reason why your pH has got affected is because of the staining in your pool which has been caused by the algae which are present in your swimming pool. The effectiveness of the chlorine decreases considerably with a rise in the level of the pH and an increase in the level of pH can possibly lead to a greater chance of the growth of algae.

When you consider ph, you have to consider alkalinity as well. There is a scale or graph if you will (you may find it on line). The ph scale runs from 0-14 with 7 being stable, however, a ph of 7 with a low alkalinity of say 100, then your water is acidic and corrosive. But a ph of 7 and an alkalinity of 300-350, you are in good shape. Alkalinity is a measurement of the water's ability to absorb an acid, it comes from calcium such as water flowing over limestone rocks. Buy a test kit and if your close in these two parameters, then I would'nt worry about it. Most pool plumbing is plastic now, so corrosion is not much of a problem.
