Can salt increase spontaneously without addition of salt (to my best knowledge)? Weather about 8 degrees warmer this week. Pool level same. No water added or removed. Is it safe in short run?
Salt level 3600 last week and 4000 today! Causes?

How are you measuring salt?
The readout from a SWCG can vary a lot because of how each unit measures salt.
The proper way to measure salt is with a Taylor test kit K-1766.

TY! This is the read out from the Aqua logic control panel. It’s always been between 3200 and 3600 up until last couple days. So my question is why would it change on this machine?
The machine is inaccurate. Drop testing is too but less so.
The SWG uses conductivity and not chemistry to determine salinity. Other metals like calcium skew the test, and temperature skews it also. It can be all over the place in consecutive tests.
Taylor tests are good to 1 drop, so even there, you could have been 3800 and tested 3600 last time and 4000 time, and both been acceptable.
Most of us let it be until the SWG complains. If we're lucky, we happen to randomly test salt when it's close to triggering the low salt alarm.

Hayward SWG cells do not have a conductivity sensor. They use volts and amps to calculate a salinity. The calculations can be thrown off by water temperature as higher water temperature draws more amps and it reads higher salt.
Use a salt drop test to determine your actual salt level.

Ok I just started my first water analysis exercise with the TFP kit salt pro.
The cl appars to be in the 5-10 range and the ph is very high at 8.2
I live in Florida and as indicated by set up I have a SWG pool and I plan on treating heavy duty iron stains with ascorbic acid. Besides aquiring vit c, algaecide, and purple stuff. This is all I have done so far.
I have questions about pH being so high. How does that happen and what are my next steps?
I believe its turning off the salt generator and waiting for clorine to drop but the high ph is not going to allow vit c treatment to be effective. Right?

Chlorine drop test: After putting approx 1 scoop of R-0870 powder in, the water turned pink as expected.
Using the purchased battery mixer I added 46 drops of R-0871 and the water turned clear. Then I hand swirled the tube for a tiny bit and the water turned pink again and it took a total of 106 drops of R-0871. Next I added the 5 drops of R-0003 and it turned pink and required 10 more drops.
To sum up:
free chlorine 53
combined chloramines 5
ph 8.2
Chlorine 5-10
Is this possible?
Ok after turning clear, about 5 minutes latter the water turned pink again and I added another 20 drops of 871 and its still pink. I need advice. I am not going to add any more drops at moment since I am so out of range

Just FYI, it's 5 Cl or 10 Br. So yours is 5+.
Aeration, high FC (test not valid at 10+ FC), or a higher TA.
What's the TA ?
Wait for the FC to fall below 10 and then test Ph.
Did you use 10ml or 25ml as the sample ?
Once it goes clear. That's it. Discard it or ignore it if you didn't dump it soon enough and it goes pink again. It's pretty much gotten us all. Welcome to the club.
For the free chlorine I used 10ml water
How do I "wait for FC to fall below 10"
Did I hear you say that it can go clear and then turn pink again minutes latter? That would affect my results big time.
How exactly should this test be performed?

The TA test went from green to light pink at 10 drops and deep pink 12 drops so TA 100-120.
So then each drop is 1/2 FC and your initial 46 drops is 23 FC.
Let it burn off in the sun. It'll take some time.
Correct. Go clear and move on. Anything that happens after that doesn't count.
Ok great. As you manage the PH in the 7s, the TA will come down on its own. It'll likely settle at 60 or 70 and at that point, it will help slow the PH rise going forward.
So what I am trying to accomplish in the short run is to prepare my pool for the ascorbic acid wash.
I believe I need my ph much lower or the Vit C won't do its trick. I am a complete novice so do not be concerned about speaking in the most basic dumb down words until I become a little more experienced. So I think I am supposed to turn off my swg to reduce chlorine but do I need to add acid to pool to prepare for vit c?

It's alot to take in at first. Please ask for clarification anytime and we will patiently slow down, rewind or repeat until you get it.
Correct. Can you wait a week or two for the AA treatment ? The FC will come down on its own but may take a bit.
You do need acid before the AA treatment.
But the FC needs to be lower than 10 to get a reliable PH reading first.
So is step 1 for me to turn off SWG? I need very basic commands here! I did turn it off just now. Now is it just a waiting game?
Sorry I missed this post. OK I turned it off When you say manage the pH in 7s, is that something that will happen with swg being off or do I truely need acid?
Great !!! Now have a beverage and wait it out.
I'm talking about normal operation after the AA treatment. You had asked why your PH was high. It won't be going forward once we tweak how you manage things.
There is a set of videos that can help guide you on each test
TF100TestKit
The TF-100 sets the standard for excellence in Pool Testing Kits. It contains 7 separate tests to give you accurate readings on each important pool water parameter.

For the FC test - add 10ml pool sample to vial, then add the magnetic stirrer and place on the mixer (turn on).
Add the scoop of R-0870 powder and then start adding drops of R-0871.
When it turns clear (I like to use the word colorless because it can be cloudy) - record the number of drops and then move directly onto adding the 5 drops of R-0003. If it stays clear then test is ended or add drops of R-0871 to go colorless again. In all the test should be complete in succession and if left standing on its own - it will go back to pink again - this is one of the most frequent questions from people doing the test for the first time. Ignore that.
When your SWCG is off, you will still need to test daily - because you are in S. Florida, the UV could affect it more so do not let it drop below minimum. Try to test at same time of day - this way you can learn how much FC loss you are getting over a 24 hr period. It is just a reference to have for future.
