Hi - We are about 5 weeks after having pebble sheen installed. All the levels are finally in line except the calcium hardness. It is hovering around 150. We have had the pool start up company for the last 5 weeks (I have been following up behind them) and I have brought up several times about the low CH. They did add calcium about a week ago but it is still low. Need opinions on letting the CH raise naturally with the fill water or adding additional now. I am in the desert and fill alot during the summer months and always battle HIGH CH so I am hesitant to add any more. I am testing all levels and my CSI is within range even with the lower CH. What are your opinions? Let it raise with the fill water or add calcium now? Thank you.

Keep the CSI in range.and let the fill water CH raise your pool water CH. Once you are at 250 ppm CH, you should switch to softened water for makeup water due to evaporation.
