If the "pH Adjuster" is the one that came with the Aquarium
Pharmaceuticals Tap Water Purifier, it contains only sodium
bicarbonate solution.  I use it with ElectroRight and haven't had any
problems at all (yes, I know, it would be cheaper to make my own ;-)
Beware of other products on the market that might contain
phosphate buffers.
