I have an annoying issue with my Deltec SC 2060 skimmer and I’m hoping you might provide some insight. It’s been running for a year now.
I adjust the fine bubbles to not go above the neck. I’ve uploaded a picture of exactly where the fine bubbles stop. https://s20.postimg.cc/i6w6lqyfh/Skimmer_Picture.png
Almost two weeks goes by and the skimmer cup fills up a little less than half the cup. The water is dark.
Turn off skimmer, empty the cup, and clean it with tap water.
Start skimmer back up. The fine bubbles are now 1/3 to 1/2 up the skimmer cup. I wait 4 to 5 hours hoping the fine bubbles will come back down. It never happens. I rotate the water level adjust counter-clockwise until the fine bubbles are back to where I want it.
I have repeated this exact process for the past few months now. For the life of me I cannot determine why I need to do this. Why don’t the fine bubbles stay where they are at after each cleaning? I have also confirmed that the water level on sump is not rising as I know this can cause it.
Can you think of any reason why this is happening?
- The surface tension of the water in the neck will be affected after the neck has been cleaned, typically the foam level will start to recover after a few hours however as the surface tension settles again and the clean surfaces start to become coated with fats and lipids.
