Starting resurfaced pool

[Kidney]

My pool just got resurfaced with pebble sheen and a measure at the water meter during fill up showed it is 14,000 gallons.

I've been following national plasterers council instructions as per directions provided by pebble sheen installer.

After 4 days, I have ph at 7.9, Total Alkalinity at 70, Calcium Hardness at 160 and a SI of 0.1.

Instructions call for TA to be 80. Should I raise my TA with baking soda to 80 before lowering ph with prediluted muriatic acid? Instructions call for pump running 24/7 for 7/10 days which aerates the water and it seems raises ph every day...

Help!

Tonight I added ~2 lbs of Baking Soda to try raising total alkalinity by 10ppm to 80ppm.

I will retest tomorrow morning with the Taylor kit I ordered through Ben's store. I hope to be doing the right thing by raising TA before trying to lower pH. Just hope pre-diluled muriatic acid will do the trick for lowering pH tomorrow without killing TA.

Once this is in order, I am supposed to add chlorine then CYA and I surely hope delaying the chlorine does not result in some algae.

If you don't have any chlorine in there, I wouldn't wait to add some or you may end up with a green pool to deal with!

Thanks Watermom!

Yes no chlorine yet. I thought of adding 9 cups of undiluted bleach (the max recommended by NPC right now) but knowing my pH is high at 8.0+ and seeing the little book that came with my K2006C says bleach is high pH, I thought I might add to my high pH/low TA issue and decided to add Baking Soda to address my lowish TA of 70.

This (rainy) morning:
Ph 8.0+ (max on K2006C)
TA 90
CH 160
Water temp: 82°F
FC 0
CYA 0
(Non SWCG pool.)

Should I wait for dusk to add my 9 cups of liquid 8.25% bleach or do it during the day today? When can I and should I add diluted muriatic acid to lower pH?

Revisiting pebble tech's warranty card, it reads "Do not chlorinate your pool until water is filtered and pH and alkalinity are acceptable. Chlorine is highly reactive and can cause metals or minerals to precipitate (cloud water, scale and/or stain)." As I know chlorine would dissipate quite fast added mid day, I first added 22.4 fl oz of muriatic acid to lower pH, which I assume will also lower TA.

I hope when I retest in late afternoon that TA will be no lower than 80 and pH at most 7.6: I can then add chlorine (using 8.25% bleach) at dusk. Tomorrow I can add cyanuric acid to the 25ppm that my installer recommended.

I will update. Hopefully I do not have to keep adjusting TA then pH for too long. I suspect running my filtration system continuously at full speed (as per installer's directions) aerates the water and increases pH: this should stop once I reach 7 days after fill up this Wednesday and drastically lower the speed of my variable speed pump.

Advice welcome!

Ok, 5 hours after adding muriatic acid:

pH = 7.5
TA = 90
CH = 160
Water temp = 83F
SI ~ -0.17

I realize these will likely change but for now I should be ready to add chlorine at dusk today and CYA tomorrow morning. Still not sure I should simply use 8.25% bleach or another type of chlorine (as bleach is high pH and I don't want pH to shoot back up).

Since I am planning to use the BBB method and will adjust daily, I don't think I need that much CYA. I was going to follow the 25ppm recommended by my installer however I have no idea how much CYA to add except for Leslie's recommending 3.5 pounds for my 14K-gallon pool: should I use a different dose the first time?
