Hello everyone...great site! I've been reading up on the pool school and its starting to make sense to me but I am a little confused. Just got my TF-100 test kit and have done 3 seperate set of tests over 4 days so far. pool has been crystal clear for past week but got up this morning and noticed a slight green line accros the edge of the shallow end right at the start of the slope. could it be Algea?
prior to this I've had problems with the whole floor covered in green stuff. Thought it was pollen (still not sure) I would vaccum to waste and a week later same thing would happen. Why the green strip???
Here are readings from last 4 days:
