So I am a loyal TFP advocate...trying to convince my brother to rethink things. He has always slightly struggled with his water.
He has a vinyl in ground pool, 16 x 32, cartridge filter, NE Ohio Located.
He has been using trichlor pucks for the last 10 years and has never tested for CYA nor has he ever changed his water.
Below are his test results from a store using a super computer (Great West)
He is ordering a test kit from TFP, but in the meantime he is panicking. I told him to DO NOTHING until he gets accurate readings. He lives an hour away, so I can not easily test for him.
Please confirm or deny what you think he should do or not do at the moment. There is NO WAY I believe of these readings...maybe FC as I know how much stuff he dumps in the pool trying to get it right.
