A couple of thoughts on Soilfloc I learned from use:

1) You can use a leaf blower to blow the "goo" back into the pond if the wind comes up and it drifts to shore - then hopefully it will sink before it blows back to shore.

2) The coarse grind recommended by Aquaben (after the regular failed to produce any noticeable results) was a disaster. I have posted 3 pictures below - the first shows what the product looks like when it fails to sink and is scooped up in a aquarium net - the second shows the product ( A and B mixed prior to application) still floating after 3 days - and the third is product being piled up on shore after being netted out of the pond (one of many piles) - this was after 5 days. 20 fish lost due to the application. And yes- I got a refund from them.
