A secondary fermenter liquid fining (mix in when transferring to a secondary) formulated from colloidal silicon dioxide so it contains no Isinglass (and unlike Isinglass, no animal products). Use 1 teapsoon per 5 gallons of beer or wine to help clear out the yeast.

IMPORTANT WINTER NOTICE: Biofine is ruined by freezing, so please do not order this if you live in an area that has freezing temperatures. Please be mindful of the time of year when ordering Biofine!

You Like Clear Beer?
Then this is what you need. Add a tablespoon to your five gallons in secondary - cold-crash for a few days, and your beer settles out super nice and clear. My home-brew has never looked better. 
Was recommended by a local craft brewer and works great for me. Economical too. Who wants to filter beer? Biofine it!

Produces beautifully crystal clear beer!
Super easy to use and the end results are nothing less than amazing. With good brewing practices (e.g., whirfloc in boil, cold crash at end of fermentation) and BioFine, beautifully clear beer is easily & quickly achievable. Adding a tablespoon to a CO2 purged keg prior to racking from the fermenter to the keg is all that is needed. After re-purging the keg, shook it good to ensure the BioFine was well distributed and then force carbonated for 24 hours. First few pours were a little murky. All the pours since have been crystal clear. Will be using this in all future brews.

Vegan-Friendly and Effective
I use 2 tsp poured into a cold keg before force carbonation. It works about as effectively as gelatin (give it a few days), but it is vegan-friendly for my vegetarian wife.

Biofine clear
Been using biofine for five or six years now. I have started going from fermenter to keg, no need for a secondary, just make sure you crash cool 40 degrees or less, I prefer 36 to 37. Awesome

Is there an optimal operating temperature for Biofine C? I know it's tempting to just say uh cold like gelatin, yet BSG makes no mention of this. I'd love to add it at 60-70F in the unitank without needing to chill that monster for energy conservation.
Most people seem to use it after a cold crash, even homebrewers.   I'm no expert on this but here is a forum discussion on Biofine application that may be of some help to you:
