No beat down.Ha.. I would agree. The NSF is a reputable organization. In fact most in not all municipal watersheds are testing our drinking water using equipment that is NSF certified. This is not science? Do you think they are using drop tests?
Not trying to argue for the sake of arguing. Maybe more of a healthy debate? these digital testing devices have gone through the same testing and certification process that the Taylor drop test kit has. In fact, the science behind it says they are certified to read CYA(and other parameters) to L1 which is higher than what Taylor provides.
What am I missing? Is it the pool store person administering the test? Is this the issue? Let’s assume they know what they are doing. If the NSF has certified the Lamotte for L1 accuracy and the Taylor drop test for L2 is that enough science?
The aquarium industry is a great example of a multi billion dollar industry embracing digital testing. Many reef keeping hobbyist have gone digital years ago. They are relying on digital test kits from Industrial systems and Lamotte to maintain parameters that require a smaller margin of error than pool parameters. Quite honestly, I was very surprised to hear the pool industry was still stuck on drop test. But then I realized it’s not the entire pool industry. It’s really just at TFP. Yes, drop tests work ok. I still use them. But so does consumer grade digital testing equipment There has to be a reason why TFP is stuck recommending drop tests??
getting ready for my beat down in 3..2..1..
but take the same water sample to 3 different stores and get it tested, and also test with the Taylor kit. See how close the results are, or are not.

An NSF L1 rating measures from 5-50ppm as shown on NSF’s site. I would think It’s not unreasonable to conclude the sample has 0 CYA.Just saw another post in another thread where the CYA result came back "5". How interesting.... like "5" is machine talk for "I dunno". In labs they normally refer to this as "too few to count" or "too numerous to count".
Yet the pool store is saying "5" and they tell you to buy some CYA. When in truth when you get your own kit it reads 90ppm or something.

agreed. It’s important to understand how the testing process works. I have 2 leslie’s within 3 miles of me. I went to both and decided to frequent the one Where the manager had some knowledge. There have been times when the results come back different than I expected. I just ask them to run the test again and they have been very accommodating. Once in a while I’ll throw’em a bone and buy a brush, or skimmer socks, etc.No beat down.
Lol that’s funny. Wait, I see a few cans of cola in one of those pillows!Ok.. I'll take the first volley...
How much do they cost? At TFP we want everyone to test their own water... and we are asking them to plop down 100 clams to buy a TF100 or equivalent. Can one of these gizmos be found a garage sale for that price... I THINK NOT!... And we would ALL have to have one so we can be on the same platform for discussing results..
I'll let the other hit you with another pillow
I do my own testing. when you spend a large amount $$ on a pool sometimes it’s worth getting a second opinion on test results.
If I can get a good digitizer that cheap, I might have to pull the trigger.Lol that’s funny. Wait, I see a few cans of cola in one of those pillows!
I use an exact iDip. Cost me $230. Works extremely well. NSF L1 for FC and Ph and L2 for CYA and CC
comes with test strips and costs around 15$ for an additional 100 FC to give you an idea of what to expect when you have to refill.
the Spintouch is $800. Each test disk is 1$. But I could care less because Leslie is paying for it..
So 'Dude.. this may be your chance to leverage that motor cycle you always wanted that your wife nixed.. You come home with a $1500 Lamote Sit and Spin.. tell her its an espresso machine for the pool.. when she says no, then pivot to that crotch rocket you've had your eyes on!
My ph method is “ it’s a little high” Poor some in from gallon then retest in a couple days. Imho PH is a range and if you try for 7.200000 all the tine you will go crazy
Personally I dispense directly from the jug to cut down on the number of transfers from one container to another. I measured out how much 1 quart, 1 pint. 1cup is with an empty jug and now I jut put tick marks on the out side of the jug. I pour to the mark and the old mark becomes the new starting point for the next time.

My method is pretty similar.My ph method is “ it’s a little high” Poor some in from gallon then retest in a couple days. Imho PH is a range and if you try for 7.200000 all the tine you will go crazy
Sometimes I don’t even check. I have learned it needs “ big splash amount “ every 2 weeks.
