Water level is steady, rarely have to add water. Rain has been mild, nothing too bad. Jim, I like your idea of bringing a sample in to warm up and then testing it.

Hi - I noticed that I keep needing to add salt to my pool every 30 to 60 days. I added a 40 pound bag about a month ago which took it up to 3200 and the salt level week over week keeps dropping lower and now it’s back to 2800 again. The lights on the salt cell show green but when I test it with...

Got it. Thank you both for your quick response 👍🏻

Hi! Can someone check my most recent test results? Everything seems to be within range but my CSI is out of range? Just wondering what is throwing it off? Also my SWG cold indicator light is on, so it’s not generating any chlorine but the level seems ok.

Not sure this is the correct area to post this. Appears I am leaking one of the chemicals on my skin when testing the water. I don’t realize it at the time until I see my skin stained brown. Any ideas of how to remove this and if it’s harmful? 🤷‍♀️

Hi! I’ve been using the app for a while now and my subscription is active and was renewed in February 2021. But every time I use the app it keeps requiring me to subscribe. I attached a picture, is there a way to resolve this?

OK not familiar with a multimeter, but will look into that. I'm guessing they sell the timer mechanism on Amazon? And what exactly is a CB?

Hi Guys - looking for some help with the timer that is hooked up to my SWG. I've noticed every couple days I need to adjust/correct the time. The timer is only 3 years old, could it be going bad already? Who would fix something like this, an electrician? I have been able to do a lot of things...

Ok makes sense. So looking back at my logs I think I maintained too high a level of FC and too low of CYA. I am going to adjust my levels to 2-4 FC and around 70 CYA. I had my output level at 20% which was probably too high. I’m going to start this one at 2% and see what happens.

Thank you guys for recommending Polytec! Received my new cell today, installed, nice to see those green lights! Question about CYA - was reading in the Pentair user guide that they recommend levels of 30-50ppm, however, the app recommends 60-90, which is what I've aimed for when testing. Is...

I found ic40 on Amazon for $765; do you know if Pentair honors the warranty if I purchase and install? Local pool company wants over $900!

Not sure, I’ll check that tomorrow. As far as cleaning I’ve done the acid clean 3 times in 3 yrs and it’s always been clean, no build up or bubbling action from the acid.

Yes right, I used the wires coming out of the cell not the ones going into the flow. So is 3 yrs a typical life? Is there anything I should be doing differently based on my logs?

Hi All - question; the flow light has been red for a few weeks, so I purchased a new flow switch. Before replacing it, I did the test by cutting the wire and twisting the red and black wires together. Turned the cell back on and the light remained red. From what I understand, that means the cell...

Thanks that’s helpful!

Hi All - noticed this white hard stuff forming in the grout lines in the coping around the pool. The picture attached is the worst one. Any suggestions for cleaning this up? I was tempted to start scraping with a putty knife or something, but didn’t want to do any damage. Thanks for all you do!

Hi - looking to understand why the red light on my SWG is on. When testing the water it shows 3200, but the SWG shows low salt? I’ve seen comments in other posts about the thermistor going bad. The SWG is only 2 yrs old. Is there anything else I should be doing? thanks!!

Ok thank you this is really good to know. That’s why I love this forum, always learning!

Sorry for the delayed response. Yes tested using the Taylor k-1766. So turn off the SWG? I was not aware, but interested. Could you expand on the reason? Thanks!!

Thanks for the feedback! Question - when I add the salt it should be when the pump is not running correct?

Hi! Wanted to get your thoughts on my test results. I believe I am sharing so hopefully you can see my logs. Salt is below 3200 target, and CSI is a little off. How critical is it to maintain CYA during the colder FL months? Love this forum and appreciate all of you!!

Yeah I just updated my signature, had an outdated test kit listed. Thanks!

Thank you, I will change the settings to share, good to know! I am using the Taylor k-2006 test kit. Don’t remember what I have in my signature line but is this kit sufficient?

Pool is a year and a half old and we do have a waterfall. And yes using the suggested amounts per the pool app.

First off let me just say I love the new app!! Nice job! I wanted to confirm I am approaching correctly. And that I have the correct targets. I seem to be adding around 24oz of acid every 3-4 days. Does that sound right? Thanks for all you do!

Hi Jim/Marty - I finally received my test kit, got the one that Marty suggested along with the Speed Stir and I've been practicing with the readings. Here are the latest. I added 1 1/2 qts of acid to adjust the PH. FC 2.5 pH 8.0 TA 120 CH 500 CYA 35-40 (not sure about this, the mixture isn't...
