Can you experts answer me a question?
On testing my FC the reading was above 5 which is my maximum. I was informed if I put 50% pool water and 50% tap water (no chlorine in the tap water) then X2 that will give me a reading up to 10. Could I then, in theory put 25% pool water and 75% tap water then X4 to be able to calculate higher FC readings.
Or is my logic failing just like my eyesight hearing and memory, fortunately I still have my good looks. lol
