I just noticed after a recent set of tests--following many inches of rain--that the target ranges for two Pool Math items changed. Example FC is now 2-7ppm. pH is now 7.2-8.0. If you look at my latest test, it's right after the rain finally stopped and I shot from the hip pouring some...

Whoaaa, Jim. IMPORTANT! [Credit to "Casablanca" screen writer.) Could you expand on that exploding cell thing? I have my Pentair IC40 powered on with a mechanical timer, thinking it's not good to power things that aren't in use. My time is set so that it turns on a few minutes after the pump...

Pool opened for the first time September 2018. Pool, spa, filter, O3, UV-C, SWCG, heater, then split to pool and spa. I normally have run the pump 8am to 8pm at 1600rmp with the divider valve set between the spa and pool returns so that the spa just barely trickles over the edge into the pool...

We don't have a landscape forum or one even subtitled landscaping, and this can make pool maintenance easier, more difficult, or an outright nightmare. We had a professional design the landscaping for our home. He also installed the larger items--ornamental trees: Eagleston Holly...

I read about this product here and looked into it. Has anyone here recent experience with them? I've used the contact form and called. No response to the contact form and voice mail when I called. It looks perfect for my Mastertemp 400--which has already been taken out of service by a rats'...

Pentair Mastertemp 400. Tech trying to diagnose a failed comm with my IC40 SWCG noticed what he said was evidence of rats nesting in my heater. Started it up, hear the fire light and about five seconds and it's off. Fan still running but no fire. Tech opined that rats had chewed the igniter...

I've thought about this a long time. Researched lots of info on uses for the condensate from central air evaporators and dehumidifiers. No it's not suitable for drinking but is for watering plants OR for topping off your swimming pool. Check out for yourself the health and safety issues...

Wow! The City of Katy, Texas (just west of Houston) is under Severe water conservation rules, with fines, threats of water cut off, and even a "report your neighbor" email address. Landscape watering is two days a week with your days based on last digit of your address, and with limited...

Just looking for company. Found this thread under "Just getting started." It ran from 2013 to 2018 with no clear and obvious answer. It's listed as an "Inactive thread" now with a recommendation to start a new one. This is it. Here's the original thread: Flying ants? Coming up on our...

I get no reply from Pentair tech support on this. My IC40 is connected via the IntelliConnect and shows up in Pentair Home. Pentair Home reports the "Chlorine Output" plus Salt Level (only Good or ?) and the Salt Cell Water Temp. The Chlorine Output is adjustable IN THE APP in 1% increments...

Pool filled October 2018. For various reasons this is the first time we're going to be away. Four days. I maintain water chemistry and use a SWCG. Pump on Intelliconnect for two run times a day. Normally I have skimmer socks on the two skimmer baskets. With recent pollen storms and my...

Never mind. Found it. Turned off at breaker while running. Fixed.

When Pentair moved their Link2O app to Pentair Home, I was disappointed. Lots of things are easier to do with a keyboard and mouse than with your finger on a tiny phone screen or even a tablet screen. I asked about that here, and someone suggested an Android emulator for PC. My phone and...

Most recent post I can find here on this topic is six years old, so I'm starting again. According to reputable sources, places like the Gulf South where I live a residential A/C can produce 15-20 gallons of condensate a day. Now there may be a little dust if you don't keep your air filters...

I have Intelliconnect and Pentair Home--PH was the replacement for Link2O which ran on iOS, Android, or Windows. Pentair Home is iOS and Android only. Has anyone installed an Android emulator and installed Pentair Home on a Windows 10 PC? I know Win11 is supposed to include an Android...

As a micro manager of pool water, I tend to get carried away, but I'm trying to do better and reduce pool maintenance to the level of only a part time job. Now that the IC40 has FC under control, I've turned to pH. I used to shoot for the middle of the 7.2-7.8 range, but 7.5 seems elusive, so...

Someone highly experienced and respected here (How are you, Marty?) once remarked as part of an answer to why higher CYA with SWCG, that the life of a cell may be about 10,000 hours. I'm not asking if that is a good estimate, but rather of what is it an estimate. In other words, is that 10,000...

I've had an IC40 only since June 1, and I've yet to find a combination of run time and % that hold FC constant. It seems I get it creeping up at .5-1.0 per day or dropping at a similar rate. My pump runs on IntelliConnect, currently 9:15am to 7:45pm at 1650 RPM and the same speed from 2-4am...

Thanks to Mike1162 for posting this link. Should be a sticky somewhere, I think, or part of pool school. It's occurred to me that the warning label on my Pentair C&C 420 (which has long ago washed and faded away) should be bigger and permanent. I'm careful anyway about releasing pressure...

I have the meter from TFTestkits.com, along with all the other stuff they sell. I have trouble with color matching, and since I generally have my FC at 6, the drop tests rarely get used. Over time, I've bought various calibration powders to mix and calibrate the meter, but recently in the...

I've kept CYA at around 40 since our pool was built in 2018. Chlorinated using liquid chlorine, alternating with Trichlor when CYA got low, worked fine. Recently I had a Pentair IC40 installed, so CYA is recommended much higher--70 to 90--and so for the first time ever, I'm actually adding...

Got a call this am that the installers might be here this afternoon to install the IC40 I bought on 5/13--weather permitting. The weather here in southeast Texas has not been very permitting the last couple weeks. Wonderful if you like to watch your St. Augustine grass grow, but not so much...

Some time in the next week or so, I'm getting a Pentair IC40 installed. I have the unit now, but the installer is backed up. I've been preparing the water according to TFP recommendations. However, I see the Pentair user manual for the IC series (15, 20, 40, 60) specifies some different...

AS of noon Wednesday the 12th. On two aisles. I just bought ten gallons, but there is still 120 gallons or more left. Don't know about later or tomorrow. They've got a sign on the shelf: One gallon equal to two tabs.

Hi guys. Freeze protection and a standby generator saved my Intelliflo 3 hp variable speed pump and associated filter and heater. The Whisperflo 1.5 hp "water feature" pump was not so lucky. I never could find freeze protection for it, and by the time I knew I had a problem...I had a problem...

Normally found in warm fresh water ponds and lakes, Naegleria fowleri, the "brain eating amoeba" has just been found in the drinking water supply of Brazosport in Brazoria County, south of Houston, presumably a by product of recent flooding from Tropical Storm Beta. Microbes and organic matter...

Hi guys. A popular tree/shrub in the Houston area--popular with landscapers anyway--is the Wax Myrtle. I even had one draw a plan and plant four in my backyard in anticipation of a pool. He said they are evergreen and provide very good privacy. The privacy thing is mostly true, assuming...

Leslies has been my liquid chlorine source, as their 12.5% product, after adjusting for chlorine content, has been a better value than Walmart, Home Depot or Lowes. In February, the price of a box of four 1-gallon jugs was $15.99, or $4 a gallon. First of March it jumped to $16.99, still...

I have a laminated instruction card that came with my TF-100 kit. Now I'm see contradictory information. Two items, plus a small clarification. * Calcium Hardness. Instructions on my laminated card say use a 10ml sample and that a result of 250-400ppm is ideal. Now I've read on this forum...

Another thread which I can't find right now suggested a high variability in the FC/CC test. That piqued my curiosity ("OK, so you've got piqued curiosity. So what?"--Barney Miller 1975.) Well, I wondered about that and decided to see what happened when I did the same test with the same water...
