Help with appropriate shock for vinyl in-ground

Hi Jim,

Where about's are you and how much sunshine does the pool get per day?

I'm in the suburbs of Philadephia, PA. Pool is on the east side of my house so it gets direct early and mid-day sun.

Ben, thanks for pointing me to the link. I have read it literally about 10 times but am still trying to get my head around the logistics of convering to a full or modified BBB regimen. I just bought a new 25 gallon tub of pucks so I'll plan to at least finish those out before I try anything drastic.
