I was having a similar experience. Somehow FC was increasing over night. I speculate that I was not getting 100% mixing. Said another way, if you add, and measure a minute later, you may get quite high or low readings if the chlorine has not mixed.

) think I might have to take a dip over the weekend if it hits 80.
Yea.. its weird... I even retested the water twice... lol.. I am sticking with the drop method, as it is what I have been basing my calculations on from the start. I want to try and re-calibrate the electronic one... have to find the testing solution somewhere... or test it against another electronic PH device
That's the general consensus with the pH meters... Right or wrong, you don't really know and you have to compare to the drop based test anyway so now your testing pH 2-3 times everytime.
I feel a better approach is to use the acid demand test to see how high the pH is when it's in the higher range of the block.

I'm not sure I know how to do the acid demand test. I have looked on the forum, I just don't know what regents to use.

CYA I tested for fun... it has some, just such a small amount that the dot doesn't disappear call it 5
The cover is on, guessing that's why the chlorine is up. Haven't added any tabs in several days...
adding acid as if 7.8 .. the electronic one has gone up every day I haven't acid, but the regent test has only moved up slightly.
The acid demand test use reagents that come in the K2006 test kit. If you got the TF100, then you don't have the reagents to do the acid demand.
You would need the 9056 test comparator, R-0004, and R-0005. It may or may not be worth it to you to purchase these items... Probably around $25 but it will provide you with very accurate pH readings since you can backtrack pH levels to the lower pH levels on the test block which are much easier to decipher.

Hmmm maybe I will get it.

So our local pool supply, Leslie's, had Regent 15, which is the acid demand test for the small tubes (they didn't have the base demand R-016). Going to use that for now. I'm guessing the bigger tube is more accurate, but this is an inexpensive alternative for the meanwhile.
I'm going to the store tonight to start buying Salt... I calculate I need 10 - 40lb bags... I can add salt a week from tomorrow and install the IC60
I also received my little robot "MiLleR" S300I - he's already to go, and not a minute too soon, my neighbor's leaves are dropping in my pool, and I'm getting tired of digging them out every day...lol one more week for him to go to work too.

Salt 400 ppm
I thought I would just test my normal water to see what I had as far as salt, so I need to add approx. 350 lbs to reach 3200 ppm.. I'm going to add 200 lbs to see where I am at (a week from now) and then add another 120 if needed, etc...
I also tried the acid demand ... one drop turned it yellow!! but one drop equals about 18 ounces of Acid.... Pool Calc tells me 7.8 ounces.. based upon 7.7 .. acid demand in the small tube might be worth it if I have a major overage of PH.
Home Depot had Solar Salt (blue bag) for $5.28 a bag... our Lowes here doesn't carry it... but they do carry the pool salt for about $6.50 a bag..

I actually like Leslie's Pool salt. It's very fine and dissolves quickly. I can't remember how much it is for a 40 lb bag though.
