have only ever used it in boilie mixes,if it has not been used on your water then you'd better get some spare batterys for your alarms,i was fortunate enough to be one of the first to use it on my old water and my god the runs just kept coming.have only ever used it at 1oz per lb of base mix,though i have seen it recommended at 2oz per lb.i once put a piece into my pond which holds around 7 carp and they wouldn't go near the stuff,so i would say you can over do it.though when i put my bait containing it in they can't get enough of it.another point i would recommend is to always use belechan in its block form,a friend of mine used the paste version once and his catch rates plummeted,once back on the solid block his catch rates went back up.the way i get it into my boilie mixes is to put it in a blender along with my eggs,it blitz's it lovely
