OK,
This is all starting to make sense. So after I get everything all cleared up I should keep my FC level around 5 due to the 60 CYA ? (Any span or just right at 5 give or take?) If I keep my FC at 5 won't the standard two tube tester show the clorine level off the chart ? (Bright Yellow) If it is off the chart wont it irratate the eye, Etc ? Having you guys to talk to is helping a lot !!! Thanks
