finer shiner how often?

[Keptafew]

This is a question for those who use finer shiner for their bait, how often do you use it?

[perchnut]

finer shiner???  never heard of it....i do use rooster booster for my ahhh...well never mind...

[kevinw]

I use it in my bait bucket everytime I change out the water.  Depending on the amount of shiners and size, I change out the water about every 3 days or so. I can keep shiners alive a long time with just an aerator and a cool place to keep them without freezing.

Every time you change some or all of the water.
Minimum of once every three weeks.
