Sounds like a good approach. Thanks Mark!

Thanks so much guys!

I'm an idiot again. Just ran the TA test again and got 110. Apparently I was confused and mixed up the TA with results from another test. Really sorry to waste everyone's time.

I apologize. Looks like I totally messed up and my TA should be 600, not 1600. I'm using the Taylor K-2006C test kit. I'll enter the correct TA number and see what I get. Do I have to limit how much Muratic Acid I add at one time?

Just tested and put my pH at 8.4 as it was definitely over the 7.8 high mark on the test tube. Akalinity came in at 1600. Pool Math is saying that I need to add 4 gallons of Muratic Acid. Does that seem right? Also, when I used Leslie's for a few months when we first got a place with a pool...

Just to close this out. The SWG was bad and Pentair replaced it under warranty. The 3-year warranty was set to expire in July, so I was lucky to get in under the gun. Thanks to everyone for your responses!

I think that you are right. The white cracks are calcium buildup, not repairs. I am leaning towards trying to do the crack repairs with sanded grout. https://www.homedepot.com/p/Custom-Building-Products-Polyblend-Plus-122-Linen-1-lb-Sanded-Grout-PBPG1221/321398560

What would be the best way to repair cracks in our water feature? Looks like the previous owners did some crack repairs with a white caulk of some kind. We'd like the repairs to look nice, but of course the most important thing would be to prevent the cracks from getting worse and having...

The cell is over 2 years old, so I don't think that it is under warranty. The install date was in July 2020. I contacted Pentair by leaving a message on their website in August 2020 because I had thought that there might be something wrong with the unit. Sometimes it didn't produce chlorine...

I was wrong earlier. The green light on the PCB is on. My PCB looks a little different than the one shown on the ICXX page. Sounds like the fuse is probably fine, since the green light is on? Any ideas as to what I should try next? Where should I check the voltage with my multimeter...

Thank you for your response! I do have a multimeter. I'm not very good with it, but I should be able to check voltages. There is no green light on the PCB that I can see, but there is a fuse on it. I'll check to see if it's blown. Great link! I am going to study it and see if I can figure...

I have a Pentair iChlor 30 SWG that isn't getting any power. The display is completely blank. It's been off for about 2 months or so now. I thought that it was off because the weather got colder here in AZ, but I just looked in the manual and it says that the water temp has to be over 52...

I'm an idiot. Today my pump kept going on and off because it wasn't able to prime. Turns out that my filter was completely clogged with a palm tree prong. I had removed one the day before so I thought that the filter was clean, but another one got in there somehow. Sorry guys...thank you for...

The heater is running and says that it is heating. It was 73 degrees here today.

I have a RayPak R8450TI-E that was purchased about 5 months ago. We turned it off for 2 months during the cold season and recently just started it back up. It was working fine. The setpoint was set at 90 degrees and the pool got to 84 degrees even though Arizona night temps were low. My wife...

Perfect. Thank you Mdragger!

I added about 40 ounces of generic liquid chlorine from Leslie's and am at a FC of 5.5 today. When trying to figure out how much more to add in Pool Math to get to 6-8, what type of Sanitizer say that I am using? Trichlor, Dichlor, Cal-Hypo, etc... I have no idea.

Thank you!

I unplugged my salt generator a few weeks ago because my FC was very high. It dropped slowly, but is now all the way down to 2.5. My CYA is 50. I plugged my SWG back in, but I see that our high temperatures aren't going to be up in the low to mid 60's until the middle of next week. Should I...

Well, hi neighbor! i:) These tests get harder and harder. Haha. I ran the CYA test again, following the detailed instructions. I'm just looking for the dot to disappear, not really straining I would stay. I still got a result of 40. So when I got a result of 80 I must have been doing...

Thank you for hanging in there with me and putting up with all of my ignorance and confusion.

LOLOLOLOL!!!

I needed that. Thank you!

I turned off the SWG. I did the FC test again using 10ml and got 37 this time (74 drops x .5). Thank you for setting me straight on not needing to add chlorine. I'm worried that I didn't do the CYA test accurately the first time. Just did it again and 40 is correct. I'll wait for the FC to...

I did a 50:50 dilution with the distilled water test.

My SWG has been on and running with my pump 12 hours a day. I understand that I should turn it off when I do the SLAM. I do not see where Pool Math recommends how much chlorine I should add. When I click on FC it says "There is no recommended chemical to lower free chlorine levels". If I...

Sorry for my continuing confusion here. I've read the document on the SLAM process and looked at the Chlorine/CYA chart. In the chart I select the SLAM tab and it says that for my Target FC is 16 based on my CYA number of 40. So should I start the slam by adding a gallon of chlorine near the...
