wish I could say the same Val, my strawberry tart is still cloudy after 3 doses of clearing agents and we are going on 2 months plus. I really think I am going to have to run this through the filter a few times. There is about a 1/2 in. of sediment on the bottom of the carboy now. So it is still dropping, but ever so slowly. I can probably say either i used the wrong type of daiquiri mix or something just went wrong in the process somewhere along the line.
I had a batch a couple months back (I think it was my plum version) that wasn't clearing so I ran it through my filter. It still didn't appear clear when I was done but then within a few days it just dropped a ton of sediment and became beautifully clear. So I would definitely give that a try!
I don't think you necessarily did anything wrong as it sounds like others are having trouble when using a lot of strawberries.
