Hi, Brad,

Reading thru your first post, two thoughts come to mind.

One, Go get some Clorox and shock with it, not the SWG. It's cheaper and more effective. It seems SWG's are much better at maintaing a Cl level than trying to bring your ppm way up suddenly. I don't have mwsmith2's calc in front of me but You'll need somewhere around 6-8 gallons of Clorox and your algae issues will be history, I believe.

Secondly, check with your SWG's recommendations on CYA level....I think they want you up around 80ppm.

Okay....trade-out time...would you stop by my house and help me get my lawnmower running? Sounds like you could do it!!!
