I recently bought myself a pump to use for my winemaking and brewing.
It's mainly because I'm lazy and I'm sick of doing the siphoning
thing. ;-) You can also use filters in it, and while I don't know if
I'll use that option, I'm curious about when you should do it. Is it a
safe bet to think that I probably wouldn't want to use any filters
when moving from primary to secondary? I know that there's some
necessary fermentation that still takes place in the secondary, and I
was worried that I might filter out some of the yeast if I use one
this early in the process.
