JB,

Liquid shock does not shock your pool.....bringing your Cl level to breakpoint and holding it there (with liquid chlorine, bleach, Cal Hypo) is shocking...it's a verb....not a product. If you know this already, my apologies. It's not clear from your post.

Bring your Cl level up to 20ppm and KEEP IT THERE 24/7 and your pool will clear. You do not need an algaecide or a clarifier....you need chlorine.

Ben's "best guess" table will tell you how much Cl to keep in your pool. The bleachcalc will give you the correct dosage. You must test and dose accurately to shock your pool and clear it up.
