Can I combine chlorine sources by adding half the amount needed from trichlor and half with bleach. Here's my most recent analysis:
6-Nov-15 80 <20 4 0 275 7.4
Even with the low CYA I don't have excessive chlorine consumption (about 2 ppm per day drop). I'm guessing that's partly due to the screened enclosure that partially emulates an indoor pool. I will be out of town for up to 10 days so I'm thinking the best thing to do is to raise my level up to 10 ppm (half the CL consumed in 10 days) with liquid and add enough trichlor to the chlorinator for the other half of the CL that will be consumed. Even with my normal CL consumption I'd feel better getting to the normal range you recommend and this approach should get me there over time and then I'll use liquid and add trichlor only as needed from the rain water dilution I get here.
Does my plan make sense to this Pool Think Tank?
