Help balancing pool chemistry post-replastering

[HiddenRiver]

We replastered the pool with wet edge Martinique quartzite on October 28. We added 120 ounces of sequestering agent according to contractor recommendation. Pool now is 0 chlorine 70 calcium hardness 8.2 pH, 240 Alkalinity. 0 CYA. I just added 8 pounds of cal hypo which pool math says it will raise calcium 21 ppm. To get to 200 will I have to add 50 pounds??? I need a sanity check?

Did the plaster company provide you any guidance on pool start up? I have attached the Wet Edge from the website.
You do have 40k gallons so your chemical additions will be high to get to proper levels. Did you verify your volume when you filled your pool as that is the main factor on chemical volume. Also, rather than cal hypo which increases FC and CH use Calcium Hardness increaser which is Calcium Chloride that will increase CH directly.

The pool water folks charged us for 38,000 gallons. We had been filling from our well for a few hours before the water trucks started to arrive so I think the volume is about right. Thank you for the information for the Wet Edge website, didn’t think to look there! I typed the incorrect name it is Cal Plus we are adding and I understand that is Calcium Chloride. Could not add 50 pounds without a sanity check!

Do NOT add 50 pounds of Cal-Hypo! Note that will also increase your chlorine level to around 100ppm.

Pool water chemistry is different during first 28 day startup. What were the PB recommendations?

Most startup guides say no CYA for first 4 days. Keep FC between 1-3ppm.

I am so sorry I Wrote Cal hypo and I should have written Cal plus.
