I’m not sure if that link worked but I just tested my pool. I tested the salt level the other day and it was low and the pool math suggested I add a couple more bags and now I’m over the recommended level for salt. I believe it’s supposed to be 3500ppm. Also to aerate my pool; would kids swimming around help?
So after I get this settled what is the most important to check daily and weekly?
 
Link works great!

Always start on the low side and work your way up, you can always put more, but you can't take it out very easily. That being said, 4200 isn't too high, especially for a new SWCG. I would just keep an eye on the SWCG and make sure it isn't complaining about too high of salt content.

Also to aerate my pool; would kids swimming around help?
It will help a little bit, especially if they are jumping in the pool a lot, but I doubt it'll compare to a fountain or such thing. I assume you want to aerate so you can get the TA down? 100ppm isn't too bad, I wouldn't worry about it, just keep your pH in check and over time the TA will probably go down on it's own.

It'll take some time to get to know what your pool needs. You want to check FC and the pH daily for a while. Once you get to know your pool you might be able to check those less often. Check the TA and CH weekly, and keep an eye on your CSI. Keeping your CSI within range will extend the life of your SWCG.

I'm curious why you want to aerate the pool, your PH is already 7.8, aerating will increase PH.

If you want to reduce TA, you should first lower the PH to 7.2, which will reduce the TA, the aerate to increase the PH.

Yes, kids in the pool splashing around will aerate the water, as will any water feature, fountains or just pointing the jets upwards, disruption of the surface will aerate.

As for a schedule:
 
Tested today and I’ve really messed up
Everything is high and I guess I need to dump water out. When I turned on the circupool for the first time it automatically lit up to 7 on the chlorine power leveland I just kept it there. I also have just kept it running the whole time.
 
Did you add more salt...11,000 ppm? Unless you had a truckload of salt delivered, it's probably a testing error.

Shutdown you SWG for now and let the FC drift to down to the target FC for your CYA.

Retest the salt level. Are you using the Taylor K-1766 salt test kit?
 
At the 100% setting, your SWG should produce 0.4 ppm of FC each hour. Running 10 hours at 100% should raise your FC by 4.0 ppm daily. That's probably more than you'll need, but you can reduce runtime or percentage from there.

Yes I have the Taylor k-1766 kit. I checked it twice. I may have messed up cause my kids were next to me splashing and talking in the pool. I went ahead turned off the swg.

Are you using a Speed Stir, or the TFTestkit equivalent? As a newbie, my testing accuracy was dramatically improved once I got one. Worth every penny, especially on the salt test.

I can only guess, but I bet you used a 25 mL sample as opposed to 10 mL. The instructions are bit confusing as they direct you to, "Rinse and fill 25 mL sample tube (#9198) to 10 mL mark."

The test is a bit different than other titration tests. Most require you to continue adding drops until there is no color change. The salt test directions read, "Do not add enough R-0718 Silver Nitrate Reagent to give a brown color. First change from yellow to a milky salmon (brick red) is the endpoint." With each drop valued at 200 ppm, you can really skew your results chasing that brown color change.

That might be it. I used the container that comes in the box but I might have went to 25ml instead of 10ml. I’ll re-check this morning while it’s quiet.

My vote as well. The instructions state : fill 25ml vial *our brains shut off and stop reading* to 10ml. You either screwed it up, or are way smarter than most of us. 😁
 
*respectfully asks @OTPirate to update instructions to say ‘fill vial to 10ml’. I understand it will take some time to use up the instructions already printed, but after that this will stop being an issue.
 
I rechecked the salt this morning and it’s at 4200. I’m going to be gone for two weeks. I leave Tuesday. What can I do to keep it from turning green? Should I keep the swg on while I’m gone but have it turned down to low? My son will be staying at my house and I could have him turn it off and on. But I’m not going to have him mess with the pool.

Two weeks is a long time to leave a pool unattended. Having a SWG means you can replace FC loss to maintain sanitization. If your pump and SWG are not on a timer, have your son turn the pump on and off for your you. See my quote from my earlier post to set runtimes:
At the 100% setting, your SWG should produce 0.4 ppm of FC each hour. Running 10 hours at 100% should raise your FC by 4.0 ppm daily. That's probably more than you'll need, but you can reduce runtime or percentage from there.
Other things to consider:

Daily pH rise:

You can lower you pH to 7.4 before your trip and place a couple trichlor tablets in a floating dispenser. Tabs are acidic and will help to control pH rise.

Debris removal and skimmer basket cleaning:

Is this something your son can handle while you're away? If your skimmer gets clogged, you run the risk of damaging your pump.
