this forum is great
second season using BBB method, don't use the frog system anymore, best water yet.
my season is 5/15 thru 9/15 - when i closed CYA = 48
now the CYA is below 30 - (using Taylor kit the black dot is visible but a little murky even when completely filled so it could be at 20?)
should I just use pucks and powder to bring up the CYA over the next 3 or 4 weeks (not real hot in eastern PA yet), or add some CYA to get up to 35 or so?
