My LSI score this am.

Per the LSI score, I was perfect this morning. First time ever…. As per the NPC guidelines. I go to Leslie’s a couple times a week just to get a sanity check on my chemistry. I did add bleach last night and a touch more Alkalinity. Pumps ran all night on schedule. I did add some make up water...

I have added Cyanuric Acid. It’s at about 40 ppm. Sorry I missed that in my post. I am following the NPC guide my contractor gave me. They do not do start-ups so I am flying solo.

That is the test kit I use. It’s great. Easy to use. Can do everything you need.

Pool chemistry is stable except for pH. I have to add a small amount of HCl every morning to bring the pH back to 7.6 range. Ca hardness is 230ppm. Alkalinity is steady at 90 ppm. Residual chlorine is steady at 2ppm. Water temp is about 78F in the afternoon. Not much plaster dust if any. Still...

Yes

Day 7 post start up. Water is clear. Chemistry is as follows. Ca Hardness is 220 ppm, Alkalinity is 90 ppm. Free chlorine is 2 ppm. CYA is 35 ppm. pH still rises at night to about 7.8 but drops to 7.4 with a few ounces of 31% HCl. Most of the day it stays at 7.6. Brush entire surface 2-3 times a...

Not if there is a warranty claim or lawsuit…….🤙🏼

Hence the comment about the contractor…..

It’s in the range where NPT says for day three. It’s 120 ppm. Day four start increasing up 200 ppm. 👍

Bleach strength can vary. Just look at the concentration. 👍

Day 3 of my start up. Contractor put Jack’s Magic magenta on fill day. I filled with city water that’s good quality. 18 hours to fill. No metals and little calcium. The pool eats up acid to maintain pH (3 gallons of 31% so far). Started adding bleach as per NPT guidelines. Very little plaster...

Follow the NPT guidelines. PH, alkalinity, Ca hardness and free chlorine levels are critical. They tell you what the correct levels are. Brush the entire pool surface twice a day. You tube is your friend. A lot of videos on how to brush your pool. Vacuum the plaster dust. Your contractor did you...
