Half a protofloc or teaspoon of Irish moss at 10 mins in the kettle.
Recently have resorted to using Kwik Clear which is two bottles - 5mls of kieselsol and then 5ml gelatine solution half an hour later followed by cold crash at 0C until I can be arsed to keg. Beers crystal clear in a couple of days normally since I started doing that albeit my palate is not refined enough to comment as to whether those finings strip flavour out as sometimes reported.
