Euro-Reef skimmer question

[yifan917]

Did any Euro-Reef user had an experence of too much bouble overflod the collection cup all the time?

I set the water level of the skimmer at the lowest position, set the waterlevel in the sump about 4 inches high and then let it ran for 2 days none stop for it to break in my system.....but still....the bouble fill up the cup within just 10 seconds amd start to overflow......damn......

salinity is around 023, temp 77F, NO2, NO3 almost 0

PLEASE HELP~
