Been following this thread as it's similar to my own situation (my SLAM story is in another thread). We had a discussion about the consistency of readings from the FAS-DPD test. I think I'm comfortable that I'm doing the drop testing right, having done some comparison tests between the drop bottle and a 1ml syringe to dispense R-0871. Also used a 5ml syringe to get consistency in the size of my pool water sample. Having said that I still got one outlier result and a retest was needed. Also I put in 2 heaped spoons for my shock level ~24. By the way I'm on day 9 for what seemed like a very minor algae problem. I saw several 1.5ppm OCLTs through the mid-part of my SLAM. Probably the most frustrating part - so close, you think the next day it's going to be done tomorrow, and if it's not, it can get disheartening. But stick it out because you want to get it right. I'm on my second SLAM this year because I cut short last time and don't think I got all the algae, and in our weather it just grows back.
I'm switching to liquid chlorine because my inline chlorinator just isn't reliable enough, plus all the downsides to pucks. I expect to lose ~3 ppm/day at normal FC levels with my CYA ~60 (losing about 10-11 ppm/day during the SLAM). For my 16k gal pool 3ppm is 1/2 gallon of 10%/day. I'm planning to add a Stenner pump and tank and wire it to my Easytouch, just have to convince the wife of the value proposition.....
