Thanks y'all. Good info. I think I'll just let the UV run and when the bulbs burn out, we'll make the call.
I'm excited to go home and retest my CYA.
I'm excited to go home and retest my CYA.
I have a stenner pump with a bleach vat that injects chlorine to my plumbing. Search Stenner Pump here, lots of info. I connected to smart plug controlled by alexa. I test, calculate number of minutes in my head for my pump, then say "Alexa run pump for 30 minutes." I'm done. I know my pool well enough that when I go away I just setup alexa routine to pump for 30 minutes and it will maintain my pool.
@proavia Hey there. Fixed the kit up with the FAS-DPD reagents. I’ve now done this 3 times. Twice yesterday (wasn’t sure if I did it right) and once today. Both times the regular DPD showed ~4ppm. Maybe even closer to 3.5ppm. From how I read it anyway. The FAS-DPD each time took the same 12 drops (6ppm). Does that seem to make sense with what y’all have noticed? That the FAS-DPD is more accurate and will generally read higher?If you only have the K-2005 Taylor test kit, you are missing the all important FAS-DPD test. The FAS-DPD test is the most reliable for FC levels - espedially above FC 5 ppm.
Yes, I too have noticed the same trend comparing the DPD to the FAS-DPD. I rely on the FAS-DPD for my pool. I do use the DPD for my spa (while in my spa) and like running the FC a bit higher after I'm out.Does that seem to make sense with what y’all have noticed? That the FAS-DPD is more accurate and will generally read higher?
Also thanks for everyone’s help with the CYA test. I did it twice a few days back and, while still high, isn’t quite as high as I thought (or the pool store test said).
DPD reliability maxes out about 5ppm.Yes, I too have noticed the same trend comparing the DPD to the FAS-DPD. I rely on the FAS-DPD for my pool. I do use the DPD for my spa (while in my spa) and run the FC hot for that reason.
This is what I have. Curious after reading that if my 0002 is a little old. I have brand new 0001 and 0002 so I’m going to compare those tomorrow.Taylor chlorine comparator
Anyone know where I can get the Taylor chlorine / ph comparator and reagents without purchasing an entire K2006 kit (I think thats the kit it comes with)? I have the TF100 kit buy my chlorine needs to stay around 6. I typically bump it up to 8ppm each evening and and it usually drops 2ppm per...www.troublefreepool.com
From the link...
Not all Taylor comparators go to 10 ppm. What you want is the 2000 series. And you can find it here:
Amazon.com : Replacement Comparator #9056 for Taylor 2000 Series : Swimming Pool Maintenance Kits : Patio, Lawn Garden
Also be aware that if you use this comparator for your pH, you are going to want R-0004, not R-0014 that comes with the smaller pH comparators. (R-0004 is more concentrated). you can use them interchangeably, but you need to adjust the amount of drops.
Two drops of 4 is ~ five drops of 14... But I prefer to use the right comparator with the proper reagent.
No. In fact, if you have some that is undissolved, that actually tells you you added enough...Note question: do you have to wait until ALL of the powder is dissolved?
I’m seeing 2 on the nose but besides not being there in person, it’s still subjective at best. If it helps any, I use my fingers to cover the value above and below the one I want to compare. By me doing this here, it’s definitely not 1, or 3, and spot on 2.I think even from the photo you’ll agree that it’s close to 3ppm
Taylor says the drop test is simply unreliable at 3+. Maybe you see something, maybe you don’t. But like you’ve said, you’ve proved to yourself that the powder test is the way to go. I coulda told you that but it hits harder when you realize it yourself.Both drop tests indicated a ppm of 6 so that’s a fair amount of discrepancy. Any chance CYA levels could influence the DPD test
LOVE. IT. When I got mine my little one was 10 and I had her doing all the tests. She tired of it quickly but for a couple of weeks she was my chemistry buddy.I think I’ll just let my 7 year old do my DPD test while I do the FAS test from this point forward
