So my CC has crept up to something over 0.5 ppm and I decide to bring FC to shock level. For a CYA of 50 that's 20 FC.. we plug that into the calculator and.. 3 JUGS OF 10%?! That's going to cost me $12 in bleach!
...and then I remember the pool store sold me a bunch of **** for $80+ that didn't do anything to fix my problems and actually made it worse.
