    CYA testing question..

    Actually after searching more, it appears the 1720 came out over 10 years ago, lol.

    CYA testing question..

    Either way, I ordered a 1720 kit an hour ago, so I guess we'll see. I like accuracy ! Thanks for the thoughts and explanations, etc. The distance between the values still looked really small to me in the 60-80 range on the 1720 kit...... but I guess we'll see.

    CYA testing question..

    This 1720 kit came out over a year ago from what I've searched, and I watched "Jason's" video months ago, and I was like... huh?...? I use 25ML for FC all the time, I like the better accuracy, so I'm totally down for the 1720 kit if it's awesome and easier to be more accurate. How do you use...

    TFP Expert Discussion - pH and Alkalinity

    I guess I could, sure, but I'm not really that concerned about 8.1 and 8.2, since I'm not going to run my pool there. I just thought it was odd that PoolMath was lowering the CSI in those scenarios, so thought I'd mention it. My main question now is whether it's ok to have pH of 7.9 or 8.0, as...

    TFP Expert Discussion - pH and Alkalinity

    I'm still wondering about this CSI going LOWER in Pool Math when going over 8.0 pH (See my post 82). In addition..... another question regarding pH & CSI: I've seen it said on TFP that I should try and stay at 7.8 pH or below. But I've also read that going over 7.8 isn't a big deal (up to 8.0...

    CYA testing question..

    This is exactly how I do my CYA measurement.... I read it on TFP somewhere before a while back. I'm still wondering about the 2 to 3 minute wait instruction. I thought I had read somewhere on TFP that from the time you mix the CYA test (water + R-0013), you have around 4 minutes or so to...

    CYA testing question..

    Same thing I've always done too (kit instructions). I'm a TFP search function sleuth tho, so found the other instructions, lol

    CYA testing question..

    I've seen 2 different instructions on CYA test listed as official instructions on this forum..... Before today, I had never seen the "shake 30 seconds, wait 2-3 minutes, then briefly shake again, then do the test. I've always just shaken for 30 seconds, and then done the test. Am I doing it...

    TFP Expert Discussion - pH and Alkalinity

    pH & CSI question.... I was tinkering around with Pool Math in trying to look at CSI shifts with my pool test numbers. pH is about 7.9 right now, and for kicks in Pool Math (android phone app), I input 8.0, 8.1, and 8.2. I observed that as pH rises up to 7.8, 7.9, and 8.0, the CSI gets...

    I decided to do the borates ( Duda boric acid granules) at 60ppm. Hopefully that helps with my crazy fast rising pH. I dumped it in 2 nights ago

    TFP Expert Discussion - pH and Alkalinity

    Ty for the info. I've never even handled a tablet before, so I don't know what Trichlor is. I'll look into a trichlor, when we take a vacation. Still have no clue how my pH is surging

    TFP Expert Discussion - pH and Alkalinity

    My main issue, is trying to figure out why my pH rises so fast all of a sudden the last 2 months (like I said, this started 24-48 hours AFTER I added all my salt for the SWG, before I even turned the SWG on). It's kind of strange. I've tracked pH meticulously, daily, since our pool was...

    We'll see.... Brand new home / pool, in a brand new neighborhood without any neighbors yet. I suppose if I befriend somebody I can trust (future neighbor), I could buy some Acid Magic ( https://www.amazon.com/gp/product/B000KKQ8LA/ ) , and have them add some. I wouldn't want to ask a...

    TFP Expert Discussion - pH and Alkalinity

    I'm definitely trying to keep my SWG from getting scale though, and my pool , in general needs to lose some of the scale that it has (thanks to the guy that did my startup after First Fill).

    Interesting. How do you know you're leaving it at 8.2, if you can't measure above 8.0?

    If I go on a 2 week vacation, what do I do with pH? Would I just lower it to 7.0 and cross my fingers or something?

    TFP Expert Discussion - pH and Alkalinity

    I added some fill water (about 1 inch) yesterday evening (Tuesday). From reading TFP the last several months, I know Salt isn't supposed to effect the speed of pH rise, which is why it's been so confusing. I'm stumped. The times I've checked my Fill Water, my TA is 80, CH is 50-60, and PH I...

    TFP Expert Discussion - pH and Alkalinity

    When I allow my PH to get to 8.0, then I lower it to 7.6, it's back to 8.0 in 48 hours.... it's been confusing. Before adding Salt to the pool, going from 7.6 to 8.0 was more like 5 to 7 days. This happened again just this week. Sunday evening PH was 7.6, and Tuesday evening PH was 7.8. CYA...

    FC at Zero today!

    Update, it's 3:30am here, and I just added 60 pounds of pool salt and brushed the pool really good. I've read enough about SWG's here on TFP to know that often times the SWG might think the salt level is lower than it is, so I added more salt into the pool to see if somehow that gets the Cell...

    FC at Zero today!

    My Pump Runs 24/7. Should the Cell section of the SWG out on the equipment pad always have a Green Light, if the Cell is actually turned on and working? (My CELL section of my SWG has zero lights on)

    FC at Zero today!

    I've measured Salt 4 times, it's exactly 15 drops, or 3000ppm, every time, for the last 4 days. Intellichlor in my ScreenLogic says 2,600, and shows this:

    FC at Zero today!

    I noticed that the cell light was on yesterday (Monday), but not today (Tuesday), and I noticed that my FC was much lower tonight than it was the last 2 nights, when I did my nightly test to try and fine tune it. I wonder if the SWG stopped running today. The last 3 FC tests (around 9pm every...

    FC at Zero today!

    It appears I don't have a "CELL" light on, on the physical SWG out on the equipment pad. My SWG and and ScreenLogic seem to think my Salt Level is 2600 (even tho my salt has been 3000 to 3400 since I turned it on). Is started at 3,400, and I'm now at 3,000. If there are no lights on in the...

    FC at Zero today!

    Checking in... FC was 10.0 at 11pm, and 9.6 5min ago (6:15am), so ..... Hopefully I'm good. Zero clue how I was Zero FC. Turning SWG back on now. Hope it's working!

    FC at Zero today!

    I have no way of knowing, other than guessing my SWG percentage was apparently not high enough, and letting it go on it's own for a week wasn't smart...? The thing is, i tested it and tweeked it multiple times for the better part of 3 weeks, before deciding to finally ease off and finally let...

    Ok, I'll maintain it with liquid chlorine throughout today, and do another overnight test and see where we're at tomorrow, then I'll turn the SWG back on if things seem stable.

    FC at Zero today!

    What do you mean by "maintain a slam"? I think I'm far below slam levels. Also, I'm wondering, does going from 10.8 to 10.0 count as passing criteria for the overnight test, as you said? Shouldn't I have wanted it to be 10.8 this morning, not 10.0?

    FC at Zero today!

    Ok, so I checked FC last night after sunset, and it was 6.2, so I added more to get around 10. (I have no idea how strong my old bottles of Liquid Chlorine are/were, since I haven't used them in a month)... Then before bed, I checked again, and FC was 10.8 FC, and I just checked now around...
