Hi. After successfully using my TF100 test kit on my pool for the last month, it occurred to me to start using it to check my spa as well.......Duh!
Spa is roughly 500 gallons ( we think) and has an ozonator. We have always used a granular non-chlorine shock in the past, but just this week put in some liquid chlorine to shock (water was cloudy), which seems to work great so far. After chlorine shock, spa water was clear & all looked OK. Using the TF100, FC & CC were both 0 ppm. Initial Ph reading was well over 8.2; adjusted down to 7.5. When I tried to check the TA with the water temp at 101 F, the solution never turned green, but stayed red before any addition of the final solvent.....??
Not sure what this means as the TA test seems to work fine with the 86 F pool water....... advice, please.
