>>you should also be aware that resuspension of the "flocked" clay particles is possible - but usually associated with a physical disturbance. In most situations of which I'm familiar, retreatment was necessary if/when a resuspension occured.<<

***** AS PREVIOUSLY STATED, the clay particles ARE CAPABLE of becoming resuspended in the watercolumn - due to wind/wave action or some other PHYSICAL DISTURBANCES - but the particles may be precipitated with another aluminum sulfate treatment; as they will unlikey precipitate again on their own.

Fingerling vs Lunker: Hmmm -- Quantity has absolutely nothing to do with Quality.
