I am fairly new to this forum and very new as the owner of a new 500gal Master spa with Eco Pur system. I have purchased the TF-100 testing kit to help me in keeping the spa in check. However all this has my head spinning faster that the SpeedStir, lol. I think these figures are correct as I attempted to follow the only instructions for the use of the TF-100 on youtube. These are my readings: Spa temp is 100, FC=3.0, CC=2.5, TC=5.5, PH= +8.2 as this was to the top, TA=200, CA was less than 20, and CH=70. The instructions with the ECO PUR system do not recommend the use of Bromine. I want to use the BBB method and have read pool school.
Recommended levels of chemicals according to Master Spa are Chlorine 1.0-3.0ppm, pH 7.2-7.8, TA 80-150PPM, CH 180-250. I have also tried to use the pool calculator but just cant figure it out.
Thanks in advance for your assistance
