Thanks Pat!
Currently on the 7th day of the Traditional Start-Up. Kiddos can't wait to jump in. My goal is to have them swimming by MLK weekend.

Thanks Kim. I was surprised how fast it was built, two weeks early. Just in time for Christmas.
This is very cool. Thanks for posting this, and congratulations on a beautiful swimming pool [emoji474]!

Prior to adding calcium -- what is the pH, TA, and CH of your fill water? If the CH is higher than 100 I would suggest not adding any calcium as with evaporation and adding fill water to the pool your CH will rise.
Can you add the state to your location?
Take care.

Sorry for the delayed response, work has been crazy. I will get the fill water numbers tomorrow.
I am located in Southern California.

Don't bother adding calcium as you will be fighting to keep it low soon enough. I grew up in Lakewood and I'm right down the street in LB now. On average my pool's CH raises by 100 points a year.
Interesting...I live in LB (Lakewood Village) about 3 blocks from the OP. My fill water (which I understand 'might' be from the same underground basin in E. LB?) tests at CH 60 (I've tested many times as I still cant believe it, haha). Ping, what is your fill CH?? After finding this awesome site about a month after startup(5/17) I increased to 400 and she has been holding steady since. Hope mine does not raise by 100 per year

Search for the water reports and you will see the calcium level has a wide range during the year. My fill water usually measures around 80.
What you will notice is the amount of acid you need to use to keep the pH in range. Lakewood pH ranges 7.8 to 9.0 and the TA averages around 160 like you measured which means just about every time you add water you will need to add acid to keep the pH and TA in range.
What I recommend now is continue on lowering the TA because the evaporation rate is low right now which makes it easier to lower the TA due to not having to add fill water every week. Don't adjust the calcium level and keep the pH around 7.5/7.8 when finished lowering the TA.

Ping,
Thanks for your feedback. I haven't added anything to raise CH. As far as lowering TA, I will continue to add acid and aerate until my TA reaches a good level.

This is so true. Our pool was fresh filled with city water that has TA=125 & CH=175. 2 years later, CH gradually climbed to 525ppm without introducing any CH increaser. Fill water test results from last month, TA=90 & CH=125.
@James,...how's your new plaster holding up?
Our pool received new coping, tiles and plaster and was also filled on 12/16. I went by the NPC startup guide and to date, the water chemistry level is right on. Currently, CH level is at 200ppm and I will not dare to add more. Based on testimonials from others and as observed, overtime CH will uncontrollably climbed to unmanageable level. In a district with water restrictions, it's a losing battle!
Neeways, I bypassed the salt Cell since and I have not added salt yet. My SWCG will have to wait until the water temp climbed back up to 60 F to function properly.
@Meadow, the gray plaster is holding up pretty good, it has a pretty cool marble look. Here are my numbers as of today (startup was on 12/16/2017)....
