A possible data point in favor of Al sulfate: Mardel's "Brite N' Clear", a 
product that claims to clear cloudiness and remove phosphates from aquarium 
water, lists Aluminum sulfate as its active ingredient. It also "has a 
softening effect on the water" according to the label.

Does anyone think this may actually remove phosphates? I wouldn't add it to 
my aquarium, but I've been considering trying it as a pre-treat for 
changing water.
