We have 2 rock weeping waterfalls that cross the waterline and sit in the water, each abouy 4 feet wide. pool is 1.5 years old and we are starting to see some white lines on the rock at or actually just above the waterline. Our calcium hardness is typically around 300-350. our fill water is quite hard. We've had lots of rain the past couple of weeks and calcium harness has dropped to 280.
Does anyone have insights into if the desired calcium hardness level should be shifted higher or lower based on having these rock weeping walls which sit in the water? Or on if having these rocks in the water makes the pool more sensitie to calcium levels? Or it could also be PH levels? we've alsp fought PH creep to 8.0-8.2 this summer with the heat, kids running the waterfall (have a plunge/waterfall section they like to use a lot as well), and being away from the pool this summer more than last year.
FA 2.5. FC 2.6. PH 7.8. TA 76. CYA 66. CH 279.
Yes, CYA is high. We've been moving that down since firing our pool guy who relied on too many tabs for sanitization.
Thanks!
