just got 25000 gal inground pool opened. sand filter. vinyl. did a copper test-it was 0.05. pH 7.8. chlorine, bromine-3 6.
FC 2.0. CC 1.0. CH color wasn't red but lavender-100. TA 70. CYA less than 20-black dot never disappeared. please let me know what i need to add to be able to use pool. the sick green color looks uninviting. thanks
