What is this?

[Texas Splash]

Just for reference's sake, 6 gallons of 12.5% chlorine is equal to about 38 ppm of FC.

My concern is that perhaps over the course of that last couple days you mistakenly added chlorine based on the need to go from zero to 24 and over-shot. If your FC was about 20 for example, then you added another several gallons (say 38 ppm), your FC could be close to 60 ppm which would require 120 drops to get back to clear. If that is indeed what happened, you went way over the limit.

You might try this now. As accurately as you can, either by eye or with a syringe (Rn stuff - ha), measure only 5 ppm of pool water and do the FC test. One scoop of powder, then each drop is equal to one FC, so no need for funky math. If you get 50 drops to clear with a 5ml sample size, your FC is 50.

So let's make sure of this first.. When you had to get back to an FC of 24 (from 17), did you add only the 7 ppm (1 Gal 2 cups) required to get back to 24, or did you mistakenly let the APP tell you how much chlorine was 24 ppm (almost 4 gallons)?

Last night I added 5 gallons. This morning when I tested and everything worked as normal but showed a loss I added I think about 95 ounces of 12.5 and 3 hours later it’s crazy high

oh Jesus I hope I don’t ruin my equipment but this morning it read 17 I just don’t get it. 3 hours later with 96 ounces it’s unreasonable. I’ll check in a few hours I need to go have a drink!

Try that 5 ml test I noted above once you've had your first sip.

Ok with this method it read 24 WTF??
My scoopers are a little crusty
Somehow there was contamination? I did add 5 gallons last night so either I’m nuts or there is tremendous algae eating my chlorine? I posted a pic from this morning after adding 96 pounces and finally saw one clump of gray along one seam but that’s it. Jesus I’m getting eyeballed by my neighbors with me out there all hours and jugs of chlorine rolling down the streets lol

See post - I did it and it’s 24. What the heck?

That is odd.

I did add 5 gallons last night

5 Gal is equal to 32 ppm of FC, so add that to what you may have had last night or this morning (17 ppm) and your FC should be somewhere in the neighborhood of 50.

Just as a reminder since I suspect you may be freaking out with results, numbers, etc:

10 ML water sample: One heaping scoop of powder and divide the # of drops in half.
5 ML water sample: One scoop of powder but do NOT divide # of drops. Each drop is one FC.

Yes I’ve been doing that correctly

Back from lunch- drank tea in 2.5 hrs now fc is 20. Cool but very sunny day. I struggle with the cya reading - it could be 50 but sometimes 55 but I round up to 60. So I’m going to add… I’ll go to pool math and see

Says 78 ounces

 

[Texas Splash]

now fc is 20

That's a relief. Not sure what was going on earlier, but that's a much better number. Panic mode OFF.

Per the app I added 78ounces to get back to 24. I test 3 hours later and AGAIN it’s insanely high. I did the 5 ml test and stopped at 40 drops because still deep red and I’m running low on 0871 ( ordered more).
How can this be? I’m using the calculator correctly I think. 78ounces starting at fc 20 and 3 hours later it’s over 40?
I cannot fathom what’s wrong. Ps steps are removed.

Also I looked at my log and somehow it kept auto filling to 199 ounces- not correct- I added only 78 but I guess I didn’t save the data correctly. Still confused why fc is so high!!

 

[Texas Splash]

Per the app I added 78ounces to get back to 24

78 ounces would be about 3.5 ppm of FC. Was that the number you were trying to increase by?

 

[Texas Splash]

Correction - 4 ppm. Now I see from your other post you were trying to go from 20 to 24, so that makes sense.

 

[Texas Splash]

Any chance you are using the wrong reagent bottle by mistake? I'm grasping for straws here because you seem to be doing the FC correctly. Your app gallons size looks fine and matches what you are adding. You test the FC at 20 just fine, then later after adding only 4 ppm it seems way too high. Doesn't add-up, so I'm wondering if there's a simple oversight somehow.

From 20 to 24
