I use bleach to chlorinate my hot tub. I did the dichlor then bleach method to get my CYA to 30 and now I'm sailing with the bleach. But lately I have been noticing that my hot tubbing routine (or rather lack their of) is making my maintenance difficult. The trouble is that sometimes I hot tub first thing when I get up. Then I add bleach, but then the next day I might not hot tub until before bed, so then my FC is out of wack. Basically, I don't think my method of 'adding bleach when I use it' is working. I'm wondering what your chlorine routines are? I'm guessing I can't pair the maintenence of my hot tub with the usage.
