It was an interesting Saturday night around my house! Maybe I will post a fuller report later, but will hit the high points here. Pool was full around 7:00 PM. Based on the helpful advice from Kim and Dirk and everyone else on this board, I didn't want to leave everything until today or Monday. So I broke open my test kit and figured out how to fire up the pump. Set the pump to pre-set 2, which was 1500 RPM. The start up card Kim linked to was very helpful - one step at a time. It also happened to be the exact same start up card my pool builder attached to the contract. So everyone was on the same page. My "baby test kit" was pretty basic, so I have only tested the PH, total alkalinity and calcium hardness so far.
Fill water was:
PH 8.2+ it was literally off the charts on my test kit
Alkalinity 20 PPM
Calcium 10 PPM
First reading on the pool itself, around 7:00 PM day 1, was:
PH 8.2+ still off the charts
Alkalinity 40 PPM
Calcium 30 PPM
Start up card says you need to address alkalinity before PH - need to get total alkalinity up to 80-100 PPM before addressing PH balance. So I looked at instructions on the baking soda and realized, I needed A LOT of it. I added a whole 12 pound bag and went to Walmart to get two more. Came back, added about another 10.5 pounds for a total of 22.5.
Tested water again at around 10 PM Day 1:
PH 8.2+ still off the charts
Alkalinity 100 PPM (sort of between 9 and 10 drops so maybe actually 95 PPM)
Calcium 30 PPM
So the baking soda did what it was supossed to do, now it was time to try to bring the PH down.
Instructions on muriatic acid said to add not more than one quart per 24 hour period for 20,000 gallon pool. So for my 25,000 gallon pool I put in 40 oz. One cup at a time, diluted in a five gallon bucket of pool water. I alternated the bucket dumps between two returns and didn't put the whole bucket in a once. Sort of about a gallon at a time, pause, another gallon.
I was hopeful that this would get PH under control. I brushed the pool while I let the acid circulate. It was after midnight when I finished.
Last test last night was around 12:30 Day 1, only checked PH:
PH 8.2+ still off the charts
THis morning, checked levels again, around 8:30 Day 2:
PH 8.2+ still off the charts
Alkalinity 100 PPM (95 PPM?)
Calcium 30 PPM
Haven't seen pool builder yet, will give him a call in a little bit. I am in a bit of a conundrum. Acid instructions say not more than 40 ounces in 24 hours, but I need to get the PH down before I can address calcium, and I am afraid if I don't address calcium soon it will leach calcium out of my brand new plaster.
What do you guys think? More acid now? Or wait until 24 hours have passed from last dose?
By the way, thanks to everyone on here for giving me the confidence to tackle this myself. The start up card is great - one step at a time. That I can do. Reading he pool school materials, it is kind of confusing because there are a lot of variables and my eyes just sort of glaze over. But by taking it one step at a time, it seems manageable.
Dirk, interesting what you said about not getting plaster dust. I have a polished pebble finish, and they acid washed before filling pool. I have now brushed twice, once last night and once this morning, and I haven't seen a speck of plaster dust either! I was starting to think maybe I wasn't brushing hard enough. BTW, I wasn't able to do the water meter check because I wasn't here when they started filling my pool. Most of the time, I work from home so it is easy to supervise, but I had a couple of meetings and couldn't be here for that part. My pool is a rectangle with a very typical slope to the floor, so I think the pool estimators probably work pretty good for its volume.
This busy pool time has come at a really busy work time for me. I was hoping to catch up on work this weekend, but I'm doing pool work instead. Oh well. One thing Dirk said; He might HAVE to live with plaster for many years. I think it should be: you might GET to live with plaster for many years, if you are lucky! THe plaster we just chipped out was the original plaster in my pool, which was built around 1960. I would be happy if the new plaster lasts that long, even though I won't be around to see it!
