Hi

'Just a suggestion, but if your skimmer is powered by a pump you could put a timer on it so that it is off whilst there is food in the pond, i.e. perhaps only on at night or at least off for parts of the day.

Or what about suspending a 300cm (or longer) Cylinder Air Stone horizontally under the skimmer to form an air curtain, and connect it to a small air pump then put the pump on a timer to keep the food out of the skimmer?

'Just me thinking outside of the box. I hope it's given you food for thought... no pun intended!

I use a Linn feeder which is very good quality but it was (a) expensive and (b) the times can't be programmed for the individual feeds i.e. they are all equally divided throughout the day, which sounds good but my fish don't feed as eagerly in a morning as they do in an evening. Cloverleaf feeders were excellent for being able to alter feed times, but are sadly no longer available.
