We've had the hottest, sunniest summer on record, and my 20x40, 36,000 gallon, in-ground pool has been crystal clear every day. However ... I'm burning through tri-chlor tablets, and a recent water sample I brought to the pool store showed:
Ph: I'm unsure, but with my own liquid test kit, it doesn't give a color that's on the chart, so I'm sure it's wicked low.
Yet ... My pool has been crystal clear all summer, it doesn't have an odor. The only negatives is that the water sometimes burns the eyes. My understanding is that I need to increase TA by adding either sodium carbonate (baking soda) or sodium bicarbonate (20 mule team borax). My understanding is the former raises TA AND PH, while the later focuses solely on increasing TA. Is this accurate? Also, I've been trying to raise the PH by aerating the pool by turning the 5 jets upward to create a fountain/bubble affect. I also have a pool fountain that creates bubbles. Still, after adding about 30 pounds of baking soda and 20 pounds of 20 mule team borax, I see no increase in either PH or TA. How can this be? I'm aerating and dropping in all these chemicals, and my PH is still not registering and I think the TA is zero or close to it (I'll confirm when I bring in a sample to the pool store tomorrow). Any thoughts?
