I don't think it's so much better than anything else.

However, it is effective and I've been using it for years for:
kickstarting filters,
removing algae in ponds(but you need to put quite a lot over a longer period of time like several weeks)
when my filter dies because of something stupid I'd done, it's effective to reduce nitrite and ammonia. I suppose it's because it gets BB installed again and it gets to work immediately.

I also notice(but can't be certain), that there is better clarity to the water. Like it's gone through a sand filter for polishing. But that's in my pond and it may be because a lot of algae on the walls and water have been taken out.
