Hello - Got my pool replastered in January and calcium hardness has been creeping up since then. Todays readings are:
The CH of our fill water is 125. We do not add anything to the pool except for acid, which was daily for months and in the last six weeks we have only had to add it every 2 or 3 days.
I have no idea why my CH has risen so much since we replastered but I'm assuming it is the plaster curing. We live in drought stricken CA and have large penalties for going over our monthly allotment of water so drain/refill is not an option. My questions are:
1) What are the optimum levels I need to keep everything at so as not to cause problems? What number should I aim for with the CSI?
2) Has anyone ever done reverse osmosis (there is now a company in my area that offers it) and does it really work or does it cause other problems?
I'm trying to figure out the best course of action before my CH reaches 1000. Thank you!!
