i've been using 6% bleach at $3.00/184oz (equiv $2.10/gal) from walmart/target. it works very well, but i would prefer the convenience of liquid chlorine (pref 12.5%). leslie's sells 10% for $5.00/gal which is not exactly a bargain. can anyone recommend a better source for LC in northern nj (bergen/passaic/morris counties)? thx.
