Finally using a real test and super high CYA

What is it I need to buy for CH? 34 pounds of it per pool math.

It is calcium chloride. Some vendors call it Calcium Up
Can buy at Home Depot, Ace, even Amazon. If PM states 34 pounds, I would add 25lbs, let it mix for a day, then test again for CH. Then add what is needed to get to your target level for CH. This way you do not overshoot.

Your TA is on the low end of target, so retest that in morning.
You are on the right track. Great work in reducing CYA.

Is it a powder I just put in there and let it go? Any sock method required or brushing, etc?

Yes it’s more of a flake than powder. Just broadcast it across the surface of the pool, favoring the deep end. Usually it will dissolve before hitting bottom, but I usually brush the few random flakes on the bottom to finish dissolving it. It’s exothermic when in water so keep it dry when applying and don’t pre-dilute it.

Well good news coming from Kansas City this morning, my CYA is actually at 50, not 60. The sun helped me out versus my LED lighting I was using last night since it was after dark. I need to re-check my pH this evening when I get home, but first I wanted to make sure there was chlorine in the pool this morning, and there was... so I feel good about that.

Calcium Chloride is like salt. It won't hurt the liner or pool surfaces to sit on the bottom while it dissolves. As mentioned it is exothermic so you don't want to put water into it as that could be a heat problem but putting it into a large body of water gets rid of that concern.

So I stopped into Leslies to see what my options were, and they were out of the big containers so I left thinking I could find something else aside from 3x15lb jugs for 40 bucks each there. Can someone point me to a non-Leslie's alternative that would do the job and save a little coin?

This is what I have used from Amazon - however the price has gone up significantly.

KC gets some snow (right?), so my recommendation for next year is to set a reminder for the winter months and grab some while they stock it. It's sometimes hard to get in the summer since no one wants to buy it when no ice is coming...

Yep looks like it’s 94%.


Trouble if it’s truly in stock. Often times out of season it’s listed but not there. Nu life labs in your area lists calcium chloride as well. Not sure if they sell to general public or just institutional.

Well lets see if they actually have it. I just ordered online for a locker pickup, so they'll send one of their people on a hunt for it and save me the time :)

Yes sir... unfortunately. Not as bad as you guys have it up north though. I'll definitely have to remember to get some, but it's not something I normally buy. The pitting it causes in the concrete driveways isn't worth it. Both of our vehicles are 4wd... and driveway is flat. I'll deal with it haha.

Yeah but we get it bad enough that we can deal with it for the most part, barring a TON of it coming down right before rush hour, etc. :) We have the infrastructure all in place.

Ok, 24ish hours later I started doing my chlorine test and couldn't get the water to turn pink when I added the scoops of the powder. Put another gallon of chlorine in to make sure some is in there, but that surprises me. Is it possible to lose 7-10ppm of FC in a day without algae? My CC tested at a 1 yesterday, haven't tested yet today. Waiting for the chlorine to circulate to get a test and do an OCLT.

Weird...

Did you add calcium?

No, not yet. I bought it... haven't added it.

I tested my pH again just now too and it looks like 8+. I added about 8 Oz of MA yesterday when it took me 4 drops to get pH to 7.4

Would pH have anything to do with it?

Either way, tested FC just now and got 6.5. Will check in the morning to see if I lost any overnight.
