I mostly follow nitro's approach to water chemistry for my 350 gallon hot tub. I use the Taylor test kit and for the most part everything is fine. What I've noticed though is that when I want to raise the TA with baking soda, I also end up raising the PH. Then when I go to lower the PH with this it also lowers the TA. I've usually settle for a TA of 60 and a PH of about 7.9. Overall this gives me a CSI of 0.05 which I think is pretty great and it stays very stable, but my understanding is I should have my TA higher, like 100. So two questions? What do folks do to raise their TA without raising their PH? Do you think I should have my TA higher? Thanks in advance! This forum is great! -
I've had a hot tub for about 2 months now. It's my first hot tub so I've been obsessive over testing the water. It's a small 3 - 4 seater and about 215 gallons. I've been battling pH at TA since day one. I've been using SpaPure chemicals (that's what my local vendor sells). I always seem to having a climbing pH and a falling TA. I also had problems initially establishing bromine only to find out a month later that my phosphates were about 3 times the max range. Has anyone had experience with SpaPure products? Are they no good? Is there something else I should do, something else I should use? This past week I concentrated on pH and got it within range and it was staying there, but the TA continued to drop. Below are my readings from when the local spa place tested my water. 10/24/2015 10/30/2015 11/7/2015 11/21/2015 11/23/2015 11/25/2015 11/27/2015 12/4/2015 Bromine (2.0 - 4.0 ppm) 0 0.5 0 0.1 0 0 0.1 0.5 pH (7.2 - 7.6) 6.7 7.7 7.6 7.7 7.8 7.9 7.5 7.8 Hardness (150 - 250 ppm) 0 120 200 220 190 200 210 210 TA (80 - 120 ppm) 0 110 70 50 90 40 50 60 Phosphates (0 - 500 ppb) N/A N/A N/A N/A 1750 0 0 N/A
