Your pool is the same size as mine. 2 weeks of tabs has probably added about 20 ppm CYA so that is barely registering on the CYA test. Assume you have about that much in already, then calculate what more you need. You don't want to overshoot. I'd add about 20 ppm more to get to about 40 ppm. You could do that with 2 more weeks of tablets in the feeder (count them out to add 20 ppm CYA) or use stabilizer added separately. If you were wrong on the initial 20 ppm you probably won't be far wrong, you don't want to get over 50 ppm CYA.
It takes about a week for all CYA to show up on test so just be patient and pay attention to how the pool is holding chlorine.
Your job will be testing pH and adding MA, and also testing FC and keeping that in line with your estimated CYA values. I don't have my records handy but it seems I was testing and adding daily or alt days for a long time post - re-plaster for my pool.
As for bringing up CH, given the high TA it may be wise to monitor the CSI number (at the bottom of the Pool Calculator) for if you push it very fast while TA is still so high you may be in danger of scaling. I advise dissolving Calcium Increaser in a bucket of water before adding to your new pool. In fact, I'd add all chems to water before adding to the pool, just to be extra kind to that new finish.
I read somewhere that one should not increase CH by more than 10 lbs at a time, not sure where I saw that or why. Perhaps someone wiser can explain why. When I add Calcium, I drop the pH to a nice low 7.3 and let it circulate before the calcium, just to minimize the cloudiness that can occur, seems to work.
When I refilled, the tap water was 20 ppm CH so I had a long way to go. I added enough Calcium increaser to get the CSI to +0.5 and then kept a sharp watch on the pH and TA so that it did not go too high. I probably could have been faster but I had the time to baby it.
I get most of my chems at Warehouse Pool Supply now bought by Leslies, 4 gallons of 10% liquid shock there is same price per active oz chlorine as the 3 pack of Clorox at Sam's, MA comes in a 4 gallon box which you will need per week I believe, Calcium Increaser is cheapest by the big bucket and I used up the 50# bag the contractor left so buy a lot. I need to replace my Wall Whale brush and so I'll be off to see them pretty soon.
