So I am not sure this question has been answered before as they are are 146 pages on just this thread alone so it is kind of hard to go through all that. I have a Fluval Sea MINI in my 13.5 reef tank. No matter how much I adjust the diel it constantly over flows as seen in the picture. Is it something I am doing or is the skimmer defective and need to be replaced? (sorry for picture quality)
