Stinking hot in my part of the world (40'C in my language or over 100'F for my American friends) . It's also School holiday time which means the pool is getting a lot more use and the cover is off most of the day.
What I wanted to get some feedback on is what would be considered "normal" for FC to potentially drop on a high use day? ie with high bather load and high sunshine?
Reason I ask is yesterday my FC was 6ppm I tested today and I am at 3 ppm. As I say high use and the sun is beating down, but would that be considered normal to drop that amount in a day?
These are my figures
FC (yesterday morning 6ppm) after use all day and cover off FC today was 3ppm (I just added some Liquid Chlorine to give it a kick back up)
Other than the 3ppm drop the water looks great. I am going to try dial up my SWG a notch or 2 to try and compensate but just wanted to get a feel if the above scenario would be considered normal or do I potentially have something more sinister to worry about?
