Hi- I started my first SLAM a couple days ago and it's going well. However, I'm color blind and find the FAS-DPD test to be quite difficult. My wife was helping me with it but is now out of town, and it's pretty much a useless test to me. I don't think I'd be able to discern the exact point it goes clear, although I could have a pretty good estimate that it's within a certain number of drops. I guess target FC for non-SWCG pools is within a 5 drop range, so I should be able to tell if I'm in the right range. But that would still hurt my ability to adjust chlorine accurately. Is there an alternative?
Also, when I put the R-0780 powder into the water sample, it's never quite as pink a it is in this example video. Maybe the FC is mostly used up by the time I test it?
