I have the FAS/DPD test kit so I can accurately test the FC when I SLAM the pool. The chart says my normal FC level should be between 5 and 7ppm. If I want it at a 6, the everyday chlorine and ph test only goes up to 5ppm. I’ll run out of the DPD powder too quick unless I just test once a week? Just seeing what others are doing. Thanks in advance!

The color shade of 6 on the OTO viewer will be pretty close to a 5, so if you wanted you could use the FAS-DPD then also use the OTO and compare the color to get used to it. At some point your water may get so predictable that you skip a day here or there. But even if you take one generous scoop per day, it should last most of your season up there. See the link below.

How much are you using per test? For a test with 10ml of pool water, one blue spoonful of the powder is plenty even for chlorine levels much higher than what you have. 10g of powder should be enough for over 100 tests.
Yea I hate to admit this but I just realized I was using the flat end to do the scoop
It says “heaping scoop” so I thought the small scoop was too tiny lol. You’re right I have plenty tests left. And I’ll compare the color with the OTO test as well that’s a good idea. Thank you so much
