Ive used bp milling for a couple of years now , and previously for years with another venue I was helping out with, there is no doubt the feed combined with natrapel really works , I am seeing results with the stock as in putting weight and looking in great condition, the proof is in the pudding I have seen a massive difference to the fishery I've recently took over for the last 18 months , Ben is always helpful with questions and will always get back to you with solutions and answers, brilliant service , thanks
