I am new to this pool testing process. I am going to have to "take over" for my husband. He has been adding soooo many chlorine pucks and bags of shock to try to combat algae. Therefore, my sister in law offered to come test using the TF100 kit. She has never seen the results I'll list below. I am wondering if we need to drain or 1/2 drain the pool, fill up, and retest to get some actual viable data to move forward?
FC- did not turn colors...stayed clear, but cloudy
pH- yellow...should have been orange or red
TA- turned pink, not green
CH- 300+ (only added 30 drops, still pink)
CYA- 100+ (immeasurable?)
How bad is it? We have a gunnite pool, approximately 15,000 gallons, clean with a polaris 360 vaccuum, currently using chlorine pucks, shock, and baking soda.
