TTUHoopsFans Posted September 25, 2020 Report Share Posted September 25, 2020 Hi everyone, I am new here. I am having a heck of a time balancing alkalinity and PH in my 350 gallon Dr. Wellness X-6 hot tub. I’ve had the hot tub for about a month now and I’ve drained and refilled it twice already. I just filled it up and I spent all day yesterday getting the PH down from 8 to around 7.2-7.4. I was at alkalinity of about 100 when the PH was 8. I then began the process of adding salt yesterday and today (it has a prozone CSS5 salt system). I just checked PH and it’s now 7.6 and Alkalinity was low at like 60. If I add alkalinity increaser, I know it is going to raise my PH to 7.8 or 8 or higher. How do I get these balanced? I’m just going in circles adding alkalinity increaser and PH decreaser. The hot tub manufacturer (LPI) said to shoot for 100 alkalinity and PH of 7.4-7.5 since I have the salt system and was having a phosphate calcium issue when the PH got too high. Thanks in advance.

RDspaguy Posted September 27, 2020 Report Share Posted September 27, 2020 Sorry buddy, not familiar with that salt system, and not a fan of any. Water balance is a combination of calcium hardness, ph, alkalinity, and temperature. What are your readings right now? Some systems require lower than normal ch and alk because the cell produces a very high ph/alk when generating chlorine, which leads to scale on the cell. I would check the salt system manufacturers recommendations. 1 Quote Link to comment Share on other sites More sharing options...
