I chill my cornies in a kegerator but I am getting the chill haze lately for some reason, I use a protafloc tablet the last 15 mins of boiling and get a good cold break, I always let the beer come bright with finings before I keg it, I have the temp set at 7-9c for lager, what I cant understand is Ive had lager at this temp loads of times before without chill haze but the last few brews I have done I get the chill haze, I have raised the temp to 14c which makes it clear but it dont taste the same as when its at 7c

can any one HELP!!!!!!!!
