I have been trying to get an accurate Ph reading. I can get Chlorine readings OK but the colour of the water in the Ph section is always the same colour as the Chlorine sample. I have been adding the maximum amount of Soda Ash to get the correct amount in the pool but still get a yellow colour in the water sample.
The pool water is clear, sparkling and no hint of Algae is apparent but its tastes a little funny, sort of brackish.
Is the test liquid (phenol/) old or do I have more serious problems?
Any help will be appreciated
