Actually, not. Bleach IS alkaline, but the acidic reaction of chlorine in the water (ask Chem_Geek if you need an explanation) negates it almost perfectly. So bleach neither raises nor lowers your pH.

In that line, Di-Chlor is almost perfectly neutral in pH, but because of the chlorine acidic reaction, it lowers pH. Chlorine by gasification also makes the water VERY acidic.
