My understanding is that the alum treat is a long term fix as long as there isn't new clay that is entering the pond. The bottom may get stirred up from time to time but the existing clay from the original treatment should still have that clay bound so that it can sink to the bottom over a few days.

If there is still clay entering the pond from runoff, critters, or wind/wave action after the treatment.....those particles would have to be treated as there is nothing to bind them to.

Sadly I don't have much personal knowledge as my total experience is from reading and my one test on a 2+ quart bottle for an upcoming treatment. Would love to see some other feedback though.
