If you need to use something, try Biofine Clear A3. It’s like fairy dust.
Relatively new, though, so I don’t know if it’s available in home brewer-friendly sizes.
I wish! I’m trying to get ahead. I need more kegs though. I find that part of the problem is I have enough fermenters for the beer to sit for a while but then I end up sucking up some yeast or something when I transfer to the keg. I’m brewing twice a week at least now and still can’t seem to get an inventory ahead.
I used to use a whole packet in 5 gallons and it worked great, really fast. Upon reading in this forum that half a packet or less is more appropriate and following those instructions, it takes longer. I’m going back to a whole packet next time.
I see larger batches in your future. 
Maybe an enterprising young pro brewer could repackage the bulk pack to homebrew sizes (8 oz?)?
I think I’m one of the ones that posted that I used less. I’ve generally only used maybe 1/2 - 1 teaspoon and it’s worked well for me. On the other hand, I’m rarely in a critical hurry to clear. I’ve been able to achieve brilliantly clear beers without the use of finings so I haven’t had the opportunity to really play around with the amounts much. More probably does work better if you’re trying to get the beer cleared in a shorter period of time.
Is this the same product? They don’t mention the A3 part.
It sounds like it, but Kerry’s naming convention is a little confusing. There’s “Biofine Clear” and “Biofine Clear A3”. The MoreBeer page has the product description copied from the A3, but no “A3” in the name. I’ll probably call them to check.
It wouldn’t hurt to try a point or two lower. That will promote protein precipitation, if that is your problem.
Do you get complete conversion of the starch in the mash? If you have moderate to low efficiency you might be pulling starch out with your sparge water.
…and liver disease if you’re drinking 2 batches a week! :o
After cold crashing at 33 degrees, I’ve had great results with gelatin. Other products may do better but I doubt you’d notice the differnce. Try gelatin after crash cooling.
And the gelatin is relatively cheap too. I’ve always used one entire envelope of Knox (they come four to a box) and it gets the job quite well, and remarkably fast.
