What would a good skimmer be for a 300 gallon semi reef?

[Bblinks]

I would go with a bbk supermarin 250 or 300, 300 would be better. If that is out of the price range than an alpha cone 300 will have the almost equivalent performance as the bbk with a lower price tag. Still expensive for a skimmer but I believe it is a single most important piece of equipment for your tank.
