I have been running a Berlin Classic skimmer for about 3 months now. Last night I took out the wet dry and replaced it with a 20 gal
glass tank for a sump. I put the skimmer in the sump and attached the Mag 5 pump directly to the skimmer input. The skimmer has the 2 outlet tubes. One seems to be pretty continuous but the other pulses a bit. When the second tube pulses, it makes a gurgle sound. I don't remember it being this loud before I placed it in the sump.
Are there any tip or tricks to make this skimmer quiet? Is the gurgle noise normal?
I did have to adjust the air flow valve a bit since I had the skimmer outside the wet/dry previously. It was dumping a bunch of water through the collection cup drain tube at first.
Thanks for your help.
