I got my FAS test kit today and tested my water. I know that the water has a high chlorine level after recently battling green algae. However, the FAS test resulted in a chlorine level of 40+!
The first time I tested, I used one heaping spoon full. I did not believe the results of 40+ppm, so I retested. The second time I used 2 level scoops, but the results were the same, 40+ppm.
Is this real?
