CYA is closer to 40 than 30 so I am increasing my SLAM level to 16. I was targeting 14 this morning and FC is already down to 12 4-hours after morning dose. I just added more and will check again tonight. It is also looking a little better now after brushing the walls and vacuuming to...

Hi, I opened our pool for the season 3-days ago to already find a green pool with 50 degree water temperature. I have been SLAMing for 3-days with little to no improvement. I know I made a mistake initially vacuuming and assuming my sand filter would trap the algae. As soon as I realized...

Thanks for the reply. I think all the Algae is pretty much dead now, just cloudy. I think I will just wait and let the SLAM work like suggested. I would like to add a little Calcium to up my CSI and then install my SWG for the season. Since my PH and Alkalinity was good prior to SLAM, I...

Hi - I am doing my first SLAM since following the TFP method. Long Story short...a lot of rain and me miscalculating chlorine consumption under my mesh cover this year led to an opening algae bloom. A flock of birdz landing in what they though was a pond probably didn't help.... I started...

I have an IC40 that I put in summer of 2017 and have used it seasonally since (about 5-months a year). I replaced the flow/temp sensor once under warranty (thanks Pentair) and it is now acting up again. Over the weekend when it was hot out the flow sensor stopped working (resumed in the...

I found this just now on Amazon. Looks like it combines the best features of the popular ones so I am going to to give it a try and will report back.

I have a newer liner that I put in in fall of 2016. My previous liner was an unknown age and also unknown how the prior homeowner managed chemistry. I have an original Aquabot, but it destroyed the pattern on my previous liner, so I haven't used in in 5-years, just been manually vacuuming...

The thread linked in this post is closed to further comments so I am starting a new one. I mostly follow the TFP recommendations with the following modifications: I balance the chemicals and put the mesh cover on in late September/Early october before the leaves start falling. Since water is...

I tried the system status mode and if I did it correctly the temperature is reading 96-99F, when water temp is 83 on the Easytouch sensor... The odd part is that no lights lit up for 1,000 of hours of usage. My rough calculation based on seasonal usage for the past 3.5 years it should be...

Thanks, will check to see what temp sensor is doing later tonight.

Thanks for the replies. The IC40 is from 2016 and is run seasonally from May to September. I replaced the flow switch last year after I cleaned the cell for the first time and it went bad (no flow). The Flow switch in there right now only has 3-months of usage on it. I will open a case with...

I have an IC40 connected to an Easytouch with Screenlogic2. I saw the Low Salt light was on Friday. I checked the interface and Salt was showing at 2650. I did my own test with the Taylor kit from TFTestkits and got a salt level of 3600. I know the salt sensor is supposed to be +/- 500ppm...

Thanks for the reply. Technically my CC is less than or equal to .5. I estimate as the color has been darker and still goes clear after one drop.

Hi All, I somehow miscalculated and overshot my salt this year. Is it bad for my pool and/or SWG to have a salt level of 3800? Also, after SLAMing, I still have CC of .5 or less. Should I SLAM again? Water is crystal clear. My pool has a vinyl liner, but I have fiberglass steps so I also...

I was going to start this discussion anyway, but I have been doing this for the past couple of years with minimal algea growth. I have a Mesh safety cover that is no solid and allows water and some sunlight through. For closing I balance all the chemicals per TFP reccomendations with the...

I do this as well. Out mesh cover on when season is over for swimming so I don't need to vacuum leaves out. I test weekly through skimmer and release area near return if I need to add acid or liquid chlorine. Agreed that keeping cover off water is important. I have one return pointed up and...

I have same issue with my IC40 that is on its 3rd season. Seems like a lot of people with seasonal pools are having Sam issue after 3-4 years. I store mine outside in the shed, maybe we need to store them in a conditioned space?

I have same problem and posted more details on the previous thread.

I have the same exact issue. I have a seasonal pool and only used the IC40 for 3 1/2 seasons so far. I got the 3-year extended warranty since I purchased a pump and automation system at the same time so they sent me a flow switch for free as a courtesy. I put the flow switch in and same...

This is concerning. Look at the second to last footnote that says it cannot be killed in water with 50ppm of stabilizer (my understanding). Looking forward to a forum expert/admin to comment.

I have the same issue. Issue started after water temp rose above 80 degrees for the first time this year. Only change this year is that I had my cell cleaned for the first time. (Seasonal pool used for 3-seasons). I called Pentair and they are sending me a new Flow switch under warranty.

My in-laws SWG is not working currently. It appears to be an issue with the controller which there are numerous discussion on, but I couldn't find this exact issue. Let me know if I need to get out the volt meter and take some readings, or if someone can suggest what parts I should buy to fix...

So my in-laws pool person started out the season about a month ago by draining and re-fillin the pool instead of shocking to remove algea. Now they told them they need a new cell as it is not producing chlorine. It is only three seasons old (12-months of use). I took the cell to a local store...
