Having a major problem:
Bought some sodium perborate and added to pool thinking that it would shock the water and raise my Bromine lvl. Tested 30 minutes after shocking to find that my DPD test showed 0 Br reading.
Thought that the perborate might have bleached out the colour of my DPD i then tested the water by adding 2 - 3 drops of sample into vial with tap water again the test failed to show any slightest of colour.
I also noticed that my water started to cloud. I was using PMS before i switched and my DPD test always showed some colour before colour gets bleached.
Can anyone tell me if adding Sodium perborate is okay? And do i have any Bromine left in my pool or has the test just bleached out? And if my test has bleach outed what can i do to test my Bromine levels?
