So this is my first internal skimmer. As I was told it takes a week or so to break in. I've had it running for three days now and every time I put the collection cup on it overflows in less than a minute. I've tried adjusting the air valve and it still over flows. It's sitting at the correct water level in the sump 8". My question is, is this normal? Should I just ride it out for a week without the collection cup?
