    Where to go next ... high CYA, CH, TA ...

    Yes. A significant drain and refill is in your future. A good reason to wait though is to take advantage of "free water" falling from the sky in the next few months (which if you drain out old pool water to maintain the water level and/or allow it to mix properly and not overflow from the top...

    Where do you source chems, specifically LC?

    Nothing to add to the thread but to say hi to @ccbill - Atascadero! Great small town, we have friends down there! :)

    Borate test strips

    My strips went bad after just a couple months once open. Disappointing I know. Rebecca at TFTestkits sorted me out with credit to buy replacements.

    TF-100 purchase

    Testing doesn't happen in a closed bottle, it happens in an open test tube. Swirling while dropping is absolutely possible but if you're in TFP you're going to save enough on everything else that many people here treat themselves to the speedstir. It's available on Amazon cheaper. To your...

    Can I add any sort of "protective layer" on top of my pool's pebble finish?

    Tell us more about these "chemicals"... The water in the oceans is 3.8 billion years old! See above :) No such thing. Oh no! Please, before you go draining your pool unnecessarily, do as the above suggestions say and get a real test kit and then come back with your results. Your water is...

    Rain filling pool - questions about handling this

    A properly configured SWG, with proper other pool chemistry will have no problem 'keeping up with rain'. Side note, leased pool equipment sounds like a nightmare. You aren't sharing your test results. Don't suppose you'd like to share your latest numbers from your own test kit?

    Calcium and Stucco Dust

    Being that you're in AZ and are not using softened water, you should expect CH to rise naturally during the summer as the water evaporates off, and is replaced with water with more calcium in it (the calcium accumulates, does not evaporate with the old water). So to me the puzzle is that it...

    Calcium and Stucco Dust

    Even in a pool your size though, it would take 7lb of calcium chloride to raise your CH by 100. You said "some" dust and you skimmed it off. You also say that your CH levels were dropping... How would that be happening? CH does not evaporate off. I think it's more likely to be testing...

    Jandy Aquapure / Nature2 Error 120 - check my troubleshooting

    Visual inspection is good. When we moved here in July 2020 the cell looked like the picture (ha! I just realized in looking for a pic to compare that that picture is literally one of my cell from a previous thread!), but since cleaning it (5:1 MA) it has remained completely clear - funny how...

    Amazing - thank you for knowing your way around their site so well!! Can't decide which of these is most appropriate? or Either way, thanks!

    Jandy Aquapure / Nature2 Error 120 - check my troubleshooting

    Yup read through that thread - lots of good advice in there and lots of weird issues that I recognize (even the 'Aquapure disappearing from the PDA but comes back if you power cycle pump' issue). Results of current tests are posted in my OP. It's seemingly intermittent so hard to chase right...

    Jandy Aquapure / Nature2 Error 120 - check my troubleshooting

    Do you mean 'the same electronically'? Totally understand that they are different form factor and the cells themselves are not compatible - I'm just wondering whether I can re-plumb onto the existing unions or if I'd need to do some PVC work too if I went down that route.

    A polite bump as I would really appreciate some input on this, especially from resident expert @JamesW who knows these units inside and out - literally! :)

    PH down

    Agreed. The answer to your specific question though is yes, it takes more dry acid (by weight) than muriatic acid to lower pH by the same amount. So you shouldn't be doing a $/lb comparison. Looking at PoolMath, it looks like it's a 4:3 ratio of dry to liquid 31.45% MA. i.e. 33% more by weight...

    Nature 2 Fusion Soft delivered instead of Aqua Pure PLC 1400. Keep or Replace?

    Looks like they're $380 right now. And Jandy only gives you a warranty if you have a "pool professional" install it. The aftermarket ones give 2 years of meaningful warranty, but I will admit reviews are hit and miss depending where you look.

    Nature 2 Fusion Soft delivered instead of Aqua Pure PLC 1400. Keep or Replace?

    I'm about to go the other direction, I suspect. Just note that the Nature2 is a bit rarer and there aren't aftermarket parts (i.e. cheap compatible cells) for the Nature2. You will be forced to buy the Jandy part as while they're electrically compatible, they are different form factor.

    Jandy Aquapure / Nature2 Error 120 - check my troubleshooting

    Hey folks. Hope you're having a good long weekend! Just wanted to double check my logic here and tag on a couple of extra questions. Getting Error 120 on my SWG, although it is still generating ok for now. Visual inspection of cell looks good. The 3 prongs at the top look ok, middle one a...

    New owner, pool turned green... test kit on the way, what can I do in the meanwhile?

    Don't do that! Only 1 scoop. How pink it turns is somewhat a factor of how much chlorine there is. No point wasting powder.

    Scale? I dunno what this is?

    Most phones from the last few years are IPxx rated, so waterproof for periods of time. I take underwater photos with mine as needed / for fun. Obviously don't go dunking your phone without checking that 😉

    Lowest safe level of CYA/Chlorine

    The observations of the article regarding "chlorine smell" etc. are nonsense and it's really hard to know where to begin untangling it. Part of the problem is that the article compares generic "pool store" recommendations and outcomes (which we here agree suck) with random and romanticized...

    Jandy Aqualink - Repair, Upgrade or Replace?

    I sent my board to the Santa Rosa guy. He had it back to me within the same week. Since your options are $150 or thousands, I'd spend the $150 first. You'll be able to use that at least until next season. Even if you then decide to upgrade, you'd have a working board to sell on eBay. When my...

    Muriatic acid prices

    Cloudy again..

    The "big guns" are already here helping, but I'm wondering how confident you are in your CYA reading? It won't have anything to do with the overnight loss but would definitely contribute towards "fragile" daytime levels.
