I shocked my pool(14000gal) with 10 gal 6% bleach yesterday to get rid of the algae. When I tested the water last night, the FC reading was 33.
However, when I tried to test the water again this morning, I didn't get any reading. I used TF test kit and followed the instruction.
Filled 10ml pool water and then put a spoon of 870 power. The water turned pink first but quickly became clear again after I shaked to mix.
What exactly this means? Too much bleach or too little?
