18 x 33 x 56" Semi-In Ground NJ

idk why I tested that I guess I was just in a groove this morning lol
Lighting is 95% of the test. You need overhead sun as directed, especially when new at it. If you have any daylight bulbs inside, compare them VS outside. While they dont come close to actual, i found the daylight LED shop lights in my garage and the highhat LEDs I put in my kitchen work great in a pinch.

You can pour the sample back and forth as many times as you need.
All tests with the 25mL sample size
Switch to 10ml and save 2.5X the supplies for FC and CH. The finer resolution isnt needed in any capacity.

18 x 33 x 56" Semi-In Ground NJ

All tests with the 25mL sample size

5/8/25 5:30am
3.5ppm FC
0 Combined
0 CYA

5/8/25 4:00pm
2.5ppm FC
0 Combined
0 CYA

Added 32oz (1 qt) chlorine
Tested again at 530 at about 8ppm FC and 17ppm combined
Dissolved 8oz of CYA in a bucket and slowly added to the pool, including what was in the rag the past week (which is almost gone) that a total of 38oz/2.375 lbs

Tested at 5:30 am this morning
5.5ppm FC; 2.5 ppm drop from last night I guess an hour isn't long enough to wait till the chlorine disperses
0 Combined
0 CYA (I know, 24 hours! idk why I tested that I guess I was just in a groove this morning lol)

First Opening Salt Question

And off we GO !!!!

When did you last add chlorine ? (Or is the SWG on?)

How does the water look ?

0 CYA can be normal after winter or a red flag.


For the block test its either or, not CL and Br 5-10. Its CL 5 BR 10. (Etc) disregard Br entirely.

And the FC block test isnt very accurate and is vague. Skip that too and do the powder test exclusively. Basically we need the block for the Ph side. Mess with it down the road one day maybe.

Quick comment on PoolMath update

Any update on pool math coming to computers/laptops?
Sorry for the delay in responding, I'm excited to be able to say........kinda. :)


Jon and I have been working once again aggressively on the App the past month with us already preforming a handful of major actions. Thing is, nobody really noticed......and that was a good thing. Just like last year was a year of bringing the App's "language" into a more modern state, this year we're doing the same with the server. We know it's resulting in nothing exciting so far, but it's a step that we had to take.

This year Jon has basically went back and redid a TON of the stuff behind the scenes on the server that's helping optimize the way data is saved, accessed, and sorted behind the scenes. This server update is the first major server action that's been taken in the 8 years of the App, and was one that was a MUST preform this year. Had we not of taken the actions we did this Winter and basically re-organized things behind the scenes there's no doubt in our minds PoolMath would have taken a dive later this year and crashed as we simply maxed out the old setup. As a result we're now in a position to handle the continued growth the App is seeing plus we've (hopefully) addressed a few other items behind the scenes few ever seen. One of the examples of this so far is the "Share API" page and the ongoing date issue where it'll show test results being saved in the future. It's our hope that Jon was able to address this issue, but we're not 100% sure as we can't really test things.

These actions have resulted in some very large hiccups so far this year that's basically crashed the servers, and to be honest we kinda knew this was gonna occur,

2025-05-09 06.15.30.jpeg


Whenever one of these "spikes" have occurred it's basically brought the App to its knees making it unusable. To help address this In we've temporarily increased the servers resources to help toss extra hardware at the issue while we worked to figure out exactly what was occurring. Jon has been aggressively tracking the root causes of these spikes down and addressing things to help continue to make things stable, and we're hopeful he's very close to being complete with all the behind the scenes rubbish that nobody really cares about. :)


Now, to directly answer your question. This year we're actually looking further at putting the Windows App to rest. We've already removed it from the App Store and I'm meeting today to hopefully get it removed from the PoolMath teaser page. The Windows App was a gamble in the very early days of the App we made, and it was one we've lost on unfortunately. We're taking the same look at how things are fairing for Amazon devices as well, as things never really took off here as well. In exchange Jon has been working more on the PoolMath WebApp that is going to allow any user to be able to address the program via a web browser. This we're expecting is going to our next focus for desktop devices and is where Jon has already pushed a few updates on a few months ago. It's still in its very early stages of testing and is still VERY messy, but we are slowly pushing forward on making this work for our users. If you'd like to give this a try we'd love some feedback that can be sent to [email protected]. We understand that the feedback will likely be overwhelmingly negative at this stage, but we are slowly working on bringing the state of this into something we can start promoting as something that's high in quality.

Service light on but no error codes

My mastertemp 400 has the service heater light is on, but there are no error codes in the panel nor on the back of the board. I disconnected the flow switch and no lights came on. Any idea what the issue might be? Attached are 2 photos showing the service led but no error code leds

First Opening Salt Question

Alrighty I took my tests. Did each twice to be sure and it was consistent. Here's what I got:

FAS-DPD
FC: 1
CC: 1.5

CYA: dot never obscured. I assume that means I have none in the pool at all.

TA: 130-140

CL: 0.5
BR: 1
ph: 8.2

CH: 450

Salt: 2,800-3000.
For the salt, my meter is reading 3300 or so. So I think I need to rinse off the sensor.

New pool owner trying to understand test strip reading

You are about the same lattitude...so same same. Cover will reduce FC consumption.
This is what I do:
  1. Don't try to micromanage the % output daily. Once you know what it takes (log everything in PM), you will learn what % to run each month.
  2. FC can drift up/down over the week. Since it is safe up to slam level just keep it within range or a bit above.
  3. With the cover on, (May, early June) I run 5-10%. June/July 15%, Aug/Sep 10-15%. You will find your ranges.
  4. When we get in to swim and cover comes off, SWG goes to 50 or 60% depending on the number of people, the sun etc. When we are done, and cover goes on, SWG goes back to baseline (or I might leave it on until 8 or 9). The increase output while swimming offsets the demand. That way I only have to change the output when we are out there, or have to wait to test at the end of the day, adjust output up, then remember to turn if off in the morning.
  5. ^^^Your cell makes 8FC in 24 hours in your pool. Mine makes 13 in my pool. Me turning it 50% on for 6 hours will make 1.5 (additional demand from swimmers). That would me you would need to run closer to 70/80/90 to make up the same. If you try this route, when you open turn it up to 80, then back down, see how that works.
This system just works for me. Might work for you!
Great info. Thanks!!

Sta-Rite System 3 S8M150 leaking

Why do you say to not run the pump a full RPM?
There is no reason, other than priming, to run a VSP at full speed.

Run your pump for a reason. Many of us run at very low speed to save $$ in electrical cost.

See:
Pump Runtimes/Speeds-->Pump Basics - Further Reading

As for new cord ring, @1poolman1 and I *may* disagree. I have followed the manual to NOT lubricate the cord ring and have found very good service (no leaks).

Enter “Diagnostic Mode” by pressing and hold the MORE button for 3 seconds, until light indicates you are in diagnostic mode.

While in “Diagnostic Mode”, you can advance to the next screen by pressing the MORE button. You will not be able to go back to the previous screen. You can only advance by pressing the MORE button.

The LESS button has different functions during diagnostic mode that are explained in the manual.

Note: Be sure you are not in Output Percentage mode (Output flashing). In this mode, pressing and holding the MORE button will only fast-forward the output setting.

Tell us what is displayed as you cycle through the diagnostics.

Sta-Rite System 3 S8M150 leaking

Is it a continuous leak or just on start-up. Those filters will sometimes leak on start-up and then stop. you should not be running the new pump at full RPM, though it will start on a higher RPM to prime. If continuous you need a new O ring. You replace them when they don't work. There is no typical time to replace. Just be glad you don't have to purchase it OEM now. For years that is all that was available and they were crazy expensive.
Why do you say to not run the pump a full RPM?

Sta-Rite System 3 S8M150 leaking

It was a continuous leak. I ended up sourcing an OEM one from my local pool store. It's very expensive at $81, but given such a critical role in the system & given it's not something I'll be buying all the time, I bit the bullet. What I found interesting & possibly helpful to others was only when I removed the old O-ring, did I notice a lot of sand in the groove below it. I was able to vacuum out some of the sand while I had to scrape out some that was a bit hard as well. That might have actually been the source of the leak, not allowing the ring to properly seat. I would have tried that prior to replacing had I realized it. I coated the new ring with magic lube & installed it. Although visually it looked like the same dimensions of the old one, it didn't compress nearly as much as with the old one. The knobs tightened down far on the old one. Going forward, I'll remove the O-ring and clean underneath it at least when closing the pool.

iCHLOR 30

So if the cell is depleted does that mean it will not make chlorine anymore?

Correct
How hard is it to replace the cell?

Unscrew two unions and one electrical connector.

And what will adding salt to the pool do still?

It may cause your salt level to be too high if you do not have a salt trst kit.

And I only run the pump 8 hours a day if that matters any
It doesn’t.

can someone help me figure out how to get my cleaner to access the whole pool without getting stuck?

originally, i had five hose sections on this and the line kept getting tangled every other day or so.

i added three floats and a sixth section of hose, but it still wouldn't reach the far shallow end.

added a seventh section of hose and another float, but it still keeps getting stuck in the deep end (and also the floats must not be spaced right, because it's still getting slightly tangled at times - you can see this in the pics).

can anyone suggest exactly what i need to do in order to make this thing reach both ends of the pool regularly and stop getting tangled? i think seven sections is the right length, but i obviously need help in where to put the floats and/or how many i need. i have four on there now, and can order more if i need to, but i'm stumped on how to move forward with this at the moment.
