The ones I've heard about others using are the same as Evan mentions from Natural Chemistry:

Pool Perfect™
Pool First Aid™ - seems to be the same as above, but stronger in strength

I had orenda™ technologies CV700 put in my pool once when the owner was out in my area and we did some experiments. There wasn't much to clear up, but it did seem to take care of some leftover suntan lotion film on the surface rather quickly, but the product also has a small amount of phosphate remover (lanthanum chloride) as well so isn't an enzyme-only product.
