over the past few days/weeks, i've been reading all about nodejs pool controller...the problem was that it has still been very difficult to find a pi4 in stock. this morning, i finally scored one from adafruit...so shortly i will begin my journey in earnest! i'm ordering the building automations...

Sunday project: replacing my old intermatic timer that controls the SWG with a sonoff R2 so I can do it from my phone and have a better control over the schedule (I'm also in the process of researching ripping it all out and going to a nixie standalone, but this is step one because the R2 is...

our IC40 is nearing the end of its life, i guess, even though the display says it is only 60% used it's almost 8 years old...so we're probably getting to the point where it will need to be replaced. trying to coax one more season or two out of it though. on that note, when i turned it back on...

how immediate of a need is replacing a slightly leaking o-ring on a pentair filter? i just noticed this morning that the filter is leaking from under the clamp: i did take it apart this past weekend to clean it, and either must not have seated it correctly when putting it back together or not...

i'm in the process of setting up an automation system using esp32 devices connected to home assistant, a few relay boards, and something to control the pump itself. is there any reason not to just use the ~ $80 flo buster device, vs the close to $200 pentair intellicomm interface? i've spent a...

i'm getting to the point where i'm going to need to do a partial drain and refill to lower my CH (started at 250 or so last july, now up to around 650). when is the best time to do this...should i do it now (or this fall), or wait until next spring?

most of the documents I've found online seem to indicate I need a 10A/250V fuse, however all of the ones I can find locally are only rated for 32V. is that a problem? I can't find anything online that will get here before late next week, and I'd rather not have to keep dumping chlorine into the...

i've got an intermatic mechanical dial timer that i want to replace with a digital timer. something like this...

i've been watching my TA drop steadily over the past few months, and for each of the past 3 weeks when i did my weekly tests i had it at 50 each time. so, i figured i'd add a tiny bit of baking soda to try to bring it up. earlier this week, i turned off my SWCG for the winter, so i added some...

during the winter when the cell is turned off because the water is too cold, am I still following the SWCG chart for the minimum and target FC numbers, or do I switch to the regular numbers until spring when I turn the generator back on?

this is the valve on my fill line (not auto fill)...I'm wanting to replace that with an irrigation valve with solenoid so I can tie it into my zwave home automation and be able to better control how much water I'm adding (and potentially also try to rig up a homemade water level sensor to...

basic question is this: if the cell is happy, does it matter what level my pool is at? I have a pentair IC40. optimal salt level is 3400. currently after adding salt back into my pool after my drain and acid wash fiasco, I'm at 3200 based on the dropper test...but the green "good salt" light...

I usually take our vac out of the pool while swimming, and I've always just closed off the suction line in the plumbing (with the pump on) before removing it. lately though, I've been occasionally getting air stuck in the system while doing so, which has led me to ask (and not really find a...

this weekend we're finally having our rocks repaired and repainted, and an acid wash done on the plaster. first acid wash since the pool was built in 2014. as such the pool will be drained and refilled. this will help me get my CH under control (right now it's extremely high at 950) as well as...

we have paraglo multi-plus lights in our pool and spa, and the pool light just went out. i'm sick of the lights going out so often and want to switch to something with a screw in bulb that i can then replace with something like the florida sunseeker pool tone bulb rather than having to replace...

our pool was built in late 2014 and started operation in 2015, and we are on our third or fourth set of pool lights (i can't remember if it's 3 or 4 at this point because i'm so annoyed with it). tonight while i was in the hot tub, our pool light went out and so i guess will need to be replaced...

so, i was just out doing my weekly maintenance, and as i was vacuuming the spa with my little hose vac i noticed there were black spots on the floor that aren't coming off. got out my bigger brush, thinking it was just some crud from the recent wind storms we've had that was stuck on...nope...

for the first time since taking over my own pool, i'm thinking about putting the solar cover on the spa (no real need to put it on the pool since we're probably not going to use it any time soon i figure, but i use the hot tub a lot and trying to cut back on the energy and time it takes to heat...

I've been using my speedstir for about 6 months now, and lately noticed I've been changing the batteries a lot. when I did my weekly tests on Saturday, the bean was jumping all over the place and not really mixing very well...so I figured it was the batteries. new batteries, same issue. tested...

a few weeks ago, my water got too cold for the cell to operate so i turned it off for the winter...i did so by pulling the plug from the power center (rather than setting it to zero and having the cell running all winter while not really doing anything). now, the question occurred to me...is...

since taking over my pool in june i've been constantly cognizant of pH, as i have a good deal of scale around the waterline as well as constant buildup in the salt cell...since the water has gotten colder though, with my very high CH (at least for now until we get our rocks repainted and do a...

wasn't sure where to put this, so I'll put it here...we are going to be away from home for probably 3 weeks to a month, and after finally taking control of my pool and getting the water perfectly balanced I now have to leave it for an extended period. also a little concerned about the fires in...

i did a thorough scrubbing of my faux rocks yesterday afternoon, followed by dumping an old gallon of chlorinating liquid into the pool because i needed to just get rid of it (and by old, i mean several years (don't ask, lol)...so not anywhere near full strength). this morning, my pH had jumped...

Moved from here. another question about this: my SWCG is turned on/off by one of those yellow dial intermatic timers, but the pump is wired direct to the breaker because it has its own schedule built in. i always do my best to make sure the times match, but i guess occasionally they can be off...

is there a good way to do this? i am pretty sure i've read somewhere hear since i started following TFP that if your water is always balanced, you should not have scaling in the cell...is that not true? my water has been nearly perfect (rarely outside of -0.2 to 0.2 even) over the past two...

i tested mine as soon as i got my TF-100, but how often should i be testing it after that? once a year? more often? never?

is waterguru not working today for anyone else? i guess they don't have active support on the weekends (which is crazy, but that's a different discussion)...and mine did not run its daily test today nor did the results come up when i hit "measure now" mid-morning. it did say that it found my...

just did my daily morning test with the K1000, and for the first time i noticed that the shade of red on the pH is obviously neither 7.5 nor 7.8, it's somewhere in between. is it valid to guess 7.6 or 7.7, or is it best practice to log it as one or the other (and if so, which one)?

i have been testing my water with both a waterguru sense and a TF-100 for about 2-3 weeks now, and i think i have everything pretty well dialed in. my ph has been reasonably stable around 7.6-7.7 (i'm only having to add acid once a week), and all the other numbers are pretty well in line with...

without getting into too much backstory (because it's confusing and i'm stupid for thinking pool store tests were ever valid to begin with): is it even possible for TA to drop from 85 to 22 in a matter of two weeks with just 3 acid additions over that time period? long story short: i'm just now...
