Please, PLEASE do not use more than the label recommends.

I don't know specifically what is is THAT brand of clarifier but the primary chemical in many of them can work in REVERSE if you overdose. So do NOT exceed the label maximum dose.

That's why we don't usually recommend using such products. They *can* help sometimes. But far too often, pool owners operate on the "if a little is good, more is better" theory. And when they do -- with that product and the metal control agents (especially, HEDP) -- you'll think you've died and gone to h. . . . , well, not heaven.
