Polyquat *is* a clarifier, though that aspect often goes unmentioned. At one time (over 10 years ago) you could buy polyquat from the manufacturer (Buckman Labs) under a different name as a clarifier. They stopped that, when they found that some folks had caught on, and were buying the cheaper, but identical, version and using it to fill algaecide bottles.
