Thanks Theo, I've always got water comeing in from springs at one end of the pond and water always going out at the other end of the pond. When I throw the pellets out they always end up at the end going out of the pond and end up in the road ditch which is nice. I haven't been able to get the fish to eat pellets this year and I don't know if it's because I was trying to use up the ones from last year which I had in my garage stored in a plastic tote? I think they were blue seal pellets for trout? Not realy sure but, I am going to try the GFC and the Aquamax and will let you know how I made out.
