I got the level up all the way.I only have 4 fish so far, they must not be producing that much waste. This is the first time I purchased a skimmer so I don't know anything about it except what I read online.
Yea, you will get that in the beginning because the thing is running amuck. You can really set it up so that its close in the neck now, it'll still create skimmate.
I was always told, that a skimmer is like a toilet, it only flushes when needed. Sometimes it'll flush more than other times.
Salinity and temp makes a difference.
