Last Wednesday we sunk 2 super sacks of AquaBlok Pond Seal in a suspected leaky area of the pond. The fish (BG + LMB) disappeared, and I haven't seen one since. Not even a minnow. Now these fish are spoiled by hand feeding, and I swear they hear me coming as they'll be waiting on me when I get to our feeding spot. They're just completely MIA since the Pond Seal was added. Additional 411, the bentonite made the water look like aqua milk. (Hasn't settle out at all, assume that it eventually will???) But it should be no different to the fish than the occasional "muddifying" that can happen after a gully washer, correct?
