Recent convert to the BBB method. Returned all my trichlor and cal-hypo "shock" (I know - its a verb, not a noun) to Costco and spent the day testing the pool after the second partial drain and fill to correct high CYA and CH.
One question though - while at Costco I noticed they are selling hth shock this year which lists a sodium salt as the main active ingredient instead of cal-hypo? Would this be a good choice for the weeks when I am on vacation and will not be able to test daily and adjust the chlorine level with bleach? I might be able to get someone to come by weekly to do a few things. What do folks usually do when they go on long vacations (2-3weeks)? My CYA finally came down to 35 ( was 120 or more), so I'm not loving the trichlor right now.
