Need helpful explanation for simple directions I guess

I recently got 6 additional FF bottles to add to FF trio. The sledgehammer was the main reason i got them but i
dont quite understand the directions.

"Combine with fertilizers during weekly feeding schedules.
Kick it through your system once with every reservoir change"


What does kick it through your system really mean. Does that mean to put just sledgehammer in some fresh water in bucket
for "X" amount of time, then flush it all out and add nutrient water as normal? If so how long is X?

I also cant completely drain my bucket, because of the setup about .3 gallons stays in the bucket at res changes. will that be a problem with sledgehammer? Also FF product boomerang im wondering the same thing about.
