Feeding tube

[seanm001]

I have a colony of sun polyps I'd like to mount under an overhang. Any suggestions on the best way to target feed it? I'm thinking a u-shaped feeding tube / bulb combo would be nice, but I can't find any such thing by searching. Does anyone know of such a product or have good DIY suggestions? What does everyone else use to get food to their inverted NPS corals?

Thanks!
