I have a Hayward H400FD running on natural gas in line with my pebble sheen pool (refinished more than a year ago). It has a cupro-nickel heat exchanger. Hayward recommends a min TA of 80. I use bleach to sanitize. Would it be safe to this heater to set the TA to 70 to counter fairly frequent pH rises?
Also, I see that if I raise the CH from my current 180 ppm to the max recommended of 400 ppm, then my saturation index would be closer to 0. Is it ok to do this?
Once I have all these balanced, I am thinking of borating the pool.
Thanks,
