Thanks mate, what we didn't realize was it was a natural lake (not a commercial)although the lake was stocked with 300 carp.
25 acres and lots of natural food, not been heavily fished, so the carp were very wary of hooks, line and he usual bait boilies, pellets and nuts.
Maize and artificial pop up sweetcorn was THE bait.
Defo go back there but for at least 2 weeks.
