It has settled in now. The skimmer definitely is not silent, just makes a hum as you would expect from the bubbles being produced.
My tank is 260L and I would have preferred the D500 but who knows how long it would be for them to have stock. But the little D300 is doing a good job so far.
If you aren't heavily stocked then I would say the D300 will be fine. It is much easier to clean and maintain a skimmer that isn't shoehorned in to your sump.
