I have the readings on the pool, using Ben's PS234 Kit. The pool is 22,000 gallons, inground, vinyl liner.

FC .5
CC 0
TC .5
pH >6.8 (color was lighter than lightest color0
Alk 150
Cal 550
CYA The dot disappeared as soon as I started pouring water into the tube.

The heat exhanger in the heater has apparently corroded completely thru. The pool stores says it's due to low pH and has recommended adding pH Up. There is also an automatic chlorinator on the pool.

Thanks for any help anyone can give me!!
