Macro Aqua M-50 Mini Hang-on External Protein Skimmer, just got it 2 days. It took a while to dial in, got it foaming perfect today all day, then I fed my fish this evening, and foam disappeared not making any difference adjusting it. Checked all lines no sign of clogging. See below (typo on C) in troubleshooting info. I find it odd to stop making skimmer after good water quality. Was satisfied until now lol for 12 hrs. Does anybody have this problem happening?
I think I realized my problem. It was the frozen brine shrimp. Apparently the oils mess with the surface tension. I dosed my tank with some vinager and foam came back shortly after that.
