I've had this skimmer for almost a year. Deltec SC2060. I've had the hardest time getting it to dry skim constantly even though it has an adjuster. It dry skims for a day or two. The 9" of water is the exception not the norm. I have a Rea Sea Reefer. It has a bubble trap that needs to be cleaned. A little debris in it, water level raises.
Want to test this method by raising it a little over an inch. Sitting close to 8" now. If it doesn't work out, I'll just remove it.
