The plaster was finished on or around 10/24, and the fill took two days.

OK, so you're kind of past the usual 30 day curing period. What are you latest test results? If you can keep your CSI near 0 or even very slightly positive, you'll be ok. New plaster is always going to put upward pressure on the pH so you can probably target a pH of 7.6-7.7 and that would be good (easier to say if you post exact test results).

Here they are:
FC 5
CC .5
CYA 60
PH 7.8
TA 90
CH 50
 
Just ran the test again. Same result. Looks like I'll be getting some calcium chloride from the big box store tomorrow... :mad:

As you may recall, I am on well water. Looks like the PB did not properly set CH levels when filling up the pool.
 
Wow, yeah, that is waaaay too low. Your CSI is below -0.6. I do remember your well being low CH and I had plans to come by a steal your water ;)

Definitely get some calcium chloride in there. You need a minimum of 250ppm CH. BUT, but, do it slowly and in increments! I think it's weird your tests are coming out so low so maybe add 100ppm of calcium and see if your test results can confirm it before you dump in the entire batch of road de-icer.

Now, I know that the big box store does unreliable tests so don't chastise me. I brought them a water sample when I went for chlorine thinking I could save on reagents... They came back with total desolved solids at 200. Since the PB was doing the chemicals and I only started taking over today, checking the CH was not top of mind. I don't mean to be making excuses - the fault is mine for trusting the PB. I hope there isn't any damage to the plaster and/or heater.

PoolMath tells me I need 33lbs of the stuff or 3.3 gallons. I'll add a little at a time - how long does it take to dissolve (when can I test again)? Am I better off getting liquid de-icer (if I can find it in Tucson)?
 
I would just used granular calcium chloride from where ever you can find it. You might have to bite the bullet and pay for the pool store markup as there's not a lot of demand for road de-icer in these parts.

I'll let your transgressions slide this time, but next slip up is going to cost you some smoked pork ;)

Your pool equipment is fine. Metal corrosion is caused by pH and has little to do with CH.

Pro-tip - pre-dissolve granular calcium chloride in a 5 gallon bucket and add it around the pool. CaCl2-H2O solutions get hot with mixing. It will also clump and can possibly cause localized scaling so be sure to dissolve it first before adding it to the pool.

Think I owe you a rack or two of ribs anyway. :)
I usually smoke a bird for Thanksgiving but we were out of town. I may do one (and a ham) for Xmas.

Ok, good to hear the heater should be ok. Hopefully the plaster is too. As you mentioned earlier in the thread, the pool is my baby - especially now that she is recovering from surgery.

Thanks for the tip about dissolving the calcium in a bucket first. In doing so, should I be able to retest CH soon after, or do I need to give it a few days to fully dissipate?
 
Hard to say with such cold water temps. However, we're not really in a rush here (don't worry, your plaster will be fine too) so you can give it a day to mix and retest.

Tried smoked turkey once in a Thanksgiving and have to say I did not really enjoy it. I grew up back East so, to me, turkey shouldn't have a BBQ aroma.

Now ham is an entirely different story.... :)

That really came out gorgeous...I can't believe how great that tile came back to life! My tile cleaned up nicely, but it screams "OLD POOL," so I definitely need to replace mine.

I have to say this one was great to read through for the barbecue alone! Always nice to see fellow Arizona BBQ'ers!
 
This is NOT good. Last night at dusk, I turned off the automatic water filler and placed a piece of duct tape right at the water line. This morning, I measured how far the water level had fallen - a full inch! The skimmer is now sucking air.

I have a hard time believing there could be that much evaporation overnight and fired-off an email to the PB.

Definitely not going to get an inch of evap overnight. You have a leak :( :( :(

Definitely bring in the PB. Mostly likely place is at the skimmer when they chipped out the old plaster. Hopefully it can be found and fixed quickly and easily.

Keep us updated and hang in there, it'll all get fixed.

Just for confirmation, you might want to perform the bucket test just to be able to prove you have a big differential. Do you know how to do that test?

It's HERE if you need it.

GOOD LUCK!!

I do know how to do the bucket test but took the lazy way out. Since it is losing water pretty quickly, I think we can confidently say that there is a problem.

The good news, I suppose, is that the PB replied to my email within seconds:
Do me a favor and shut off your pump and your water leveler. More often it's not necessarily a plumbing leak if there is a fitting in your pool that wasn't sealed properly we can get water leaking from there . I am going to make a call tomorrow to our guy that takes care of any leak issues that we have and see how soon I can get him out there. If it is a fitting that wasn't sealed properly we will certainly take care of it. If there truly is a plumbing leak then he can identify where the leak is at and depending on what it is we can get a price from him to fix it for you.​

Not sure I like that last sentence but will play this out to see what they find before going apey. It will be interesting to see how far the waterline continues to fall.

I am curious - what sort of voodoo will they use to determine where the leak actually is?

- Flappy
 
I am suspicious of that CH test result.....especially coming from a well in the Calcium rich Southwest.

Do you have your own test kit yet so you can get some reliable results?

What is the CH of your fill water?

Back to the CH for a second, I am sure reluctant to suggest adding CH to a pool when you haven't tested your fill water for CH. Am I missing that you did that already?

Long ago in the beginning of the post. He's on well water that has a surprisingly low CH for AZ water.
