IC-40 Dead???

Just did the night FC test and it’s at 15. Still seems like it’s dropping awfully fast.

You are killing stuff!

FC of 13 this morning...down from 15 last night.
Guess I continue to SLAM. Just added some more and will continue to monitor. Water looks great for whatever that's worth.

 

[Gnarbrah]

Went out and tested about 45 minutes after I added enough to get me back FC of 20. It read 22.5...
Maybe adjust my gallonage to 15,500?

 

[PoolStored]

Maybe, what % liquid chlorine do you have? What % did you put in pool math?
You are not logging your tests and additions, so hard to help.
If the percentage match, then no, LOWER the pool volume by 500 and test it again, 30 min after next addition.
PM thinks your pool is larger than it is...that's why you got higher results (unless there is a % problem on the LC)

My brain is dumb...
11:30 update
I changed my gallonage to 14,500
FC was 18
Added 32oz 10.5% LC (pool math says that adds 2.2)
I also brushed again this morning (teeth and pool)

Ok - big day! Last night had FC of 16.5 and this morning was 16
CC is 0 and water is clear. Guess that means SLAM is done?
Now what? Turn SWG back on and keep an eye on FC? At what level do I check CYA again?
Once I’m back in the normal zone I guess then I’ll know if my SWG is keeping up?

16.5 to 16 FC, CC is 0 and water is clear. Guess that means SLAM is done?

It does. Well done.

Now what? Turn SWG back on and keep an eye on FC?

Let the FC fall back closer to target range. Turn the SWG on at high target (ish). Mess around and find out with lots of wiggle room to minimum

At what level do I check CYA again?

Get a good test in blazing sun mid day. (At the first chance). I want to double check @PoolStored agrees before we act, but I'd raise my CYA to SWG levels. We've been splitting duties here and 'too many cooks' and whatnot. Lol. Anywho, Its plenty warm by you and you're going to stay SWG even if this one is toast.

At worst it helps the half producing SWG until you get a new one. At best the SWG is fine and you need to be at regular season levels anyway.

Sounds like we need another chef….. Wouldn’t a proper overnight gain test (now that we know OP is clean) solidify if the SWG is running at full steam - or is a racehorse with a sprained leg that may need to be replaced?

It is certainly a way to skin the cat.

It will however be available to test sooner (tonight) versus waiting a couple days for the FC to fall. So thats 2 votes for overnight gain test with a set block of hours (9?).

Won’t be able to test in the middle of the day until Saturday unfortunately. If I’d just hurry up and win the lottery I wouldn’t have this “work” thing getting in the way of stuff I want to do! I’ll assume with an FC of 16 this morning it should hold until I get home this afternoon. I’ll check it then and see what my level is. I guess I’ll just stick with LC until the weekend when I can get the readings I need?

It is what it is and we get it.

I'm almost positive you won't be hitting minimum FC also.

I’ll check it then and see what my level is

Get it at dark for the baseline (being comfortable its still way above min), run the SWG at a high% until morning and see what it made.

I guess I’ll just stick with LC until the weekend when I can get the readings I need?

Id squeeze whatever the cell would make for less jug lugging. No matter how many, id rather lug half the jugs than all of them. Plus, you already paid for the SWG FC so use it. Supplement if needed.

I'd get CYA to 60, until you can demonstrate that you can maintain FC. That way if you do have to SLAM again, it won't be as bad as doing it at 70 or 80.
Couple of months of consistently maintaining your FC at the top of the range, then to to 70.
