The break in period is caused by new plastic. new
plastic being petroleum based, caused the bubbles to
pop easier. over time, the bacteria cleans the
plastic off.

Another question I have, since the design is pretty much the same as any
other skimmer, is the real difference in the water pump? It came with an
AP1500 power head. Would getting a better head help?
I'd need it to be big enough for a 55 gallon...some ppl say get it for at
least double the size of your tank.

Also, what is the deal with a "break-in" period? This is an existing tank,
why does a skimmer have to "break-in"? All it is is plastic and a pump.
