First-time poster here. I'm super frustrated! I had a new pool built and filled just last April 2014 and have had a pool guy taking care of it for this past year - I have, however, been reading on this board a lot over the last year and am generally familiar with the basics of ABC's of pool chemistry (I know, I know, I should've just taken care of the pool myself entirely) Anyway, I've had tons of white calcium flakes coming out from the SWG the last month, and finally, today, my pool guy tells me my CH is at 800!!!! and my only option is to really drain and re-fill, which in SoCal right now is tough with the drought, etc. My pH and TA have generally been good (around 7.5 and 80-100, respectively). Also, he just tested my fill tap water today and it's only 250. What do I do?? Does my new plaster have something to do with this super high CH too? My biggest concern is that after only a year of filling the pool and doing what I feel was a decent job of keeping the chemistry in balance, my CH is out of control and if I have to refill, then how do we keep the CH under control going forward so this isn't an annual occurence?
Thanks for any suggestions - I love reading posts on this forum and all the nice people here!
