Thank you for all the information you've given me. I did order the test kit you suggested. I won't have it until the weekend. In the meantime, the water is clear now.
I do have an indoor swimspa, and I keep it covered when it's not in use.
I'm using a test strip. The alkalinity is fine 80-120. The ph is always around 6.8 I use dichlore (Spa 56 (99%)) to sanitize.)I'm actually using alkalinity increaser...sodium bicarbonate because I was told it would level out the ph. I haven't tried baking soda yet.
Thanks so much for any help you can give me with this.
I have a 2,000 gallon swimspa pool. The ph is always low. I'm not sure how much baking soda to add at a time before waiting an hour and retesting. I know for the spa side I add one ounce for the 450 gallon hot tub. Thanks so much for any help with this issue.
