26,000 gallons of new water trucked in after a brand new plaster job. I've only replastered once in 35 years! Want to try BBB/TFPC after many years using copper/silver along with low level of tri-chlor 3-inch tabs. It worked well for water clarity, etc., but eventually the copper stained the plaster and left us with somewhat green tint in hair after a long summer of use! So need some advice on getting things going and whether there are special considerations for TFPC in new plaster situations..does the calculator take those things into account? I have a new Taylor K2006 on the way. Not sure about the reagents in the older LaMotte kit I have. Thanks
