I know this will be a dumb question for some, but here 'tis.
I have carefully monitored FC levels over the last several weeks, well, since discovering BBB awhile back. At around FC 4.0 I was getting some wide spread green algae growth to the point of shocking to 15ppm at my CYA level of 30.
This evening I measured the FC level at 2.2 with CYA at 20 - I've added some water to the pool over the last several weeks.
I've been trying to hold the FC at 5 - something tells me I can't get there with CYA that low. So, just about every evening I've added two 96 oz. bottles of 6% bleach to bring the level back up to 5 - according the the new and improved calculator.
Adding bleach to the water everyday is common? Not that it's a problem, but what do you think? What needs adjusting other than maybe the CYA number?
Thanks - and cheers !!!
