My pool is 1 year old, pebble finish/gunite pool.
PH 7.4
FC 4.5
CC 0
CYA 40-50
ALK 70
CH 250
My ALK has come down over time. In looking back over my PS-233 kit log it started at 115 and is now down to 70 after about a years time. I have never added baking soda to increase it. I normally have to routinely add acid to lower PH about once a week.
With an ALK of 70 should I look to increase this up to 90 ro so ? Would it help keep my PH more stable ? I wonder if my spa spillover and waterfalls have lowered the ALK over time ? I have a 3-4 foot high waterfall over a grotto, another waterfall in the pool, a spa spill over which runs when the filter runs and a waterfall inside the spa and a slide. Would this provide the areation to lower my ALK over time ?
Normally the spa spill over runs all the time when the filter runs but the others are just on when in use.
thanks,
