How are you getting TA 145 it only moves by 10. As for the CYA test you can pour it back into the mixing bottle and do it again and again. Needs to be a bright sunny day with the sun behind you, vial in front of you shaded by your body at waist level. Fill vial line by line checking till the black dot is gone. That would be your CYA number.Alright y'all, here it is.
Free chlorine is 10. CC are less than 0.5. Here's why I say that. After I put the R003 in the water in the vial was eeeever so slightly tinged pink. I wouldn't call it red. Just a slight pink think. When dropping one drop of reagent in on the next step immediately fully clear with no pink tint. .
TA is 145. Calcium hardness I measured to be 300.
PH is 7.8.
Is the block test the only PH test at our disposal? It seems quite subjective, and a lot of room for error between those last 3 blocks.
CYA. Whew, this one is tough. I feel like I could get a different result 10 times in a row, then hand it to someone else and they would do the same, different from me. If I walk outside with a different back drop below me and different lighting, I can see the eyeball when I couldn't inside.
Anyway I got just a tick over 60 on my CYA test this time.
I'm assuming after time, my testing procedures will get better, and I'll sort of calibrate my testing by watching how the different test results work together when I add certain chemicals. For example, if my FC continually shows higher than expected after adding the dose recommended of bleach, then I can surmise that perhaps I'm thinking the cya is more than it really is.
Don't waste your time. It will only confuse these and make make you doubt your own results. I still go to Leslie's if I need unicorn floaties and skimmer nets, but that's about it.I am tempted to take another sample in to them to compare to my tests. They test for free.
