Hey RC! I have a bubble-magus NAC-6 protein skimmer running my 100 gallon reef. Last weekend I was tuning this old NAC-6 skimmer and the past few days after I tuned it, the collection cup has been pulling out SO much dark green skimmate. Literally, 1 collection cup full of skimmate PER DAY. Before, it would take about 1 week to fill the collection cup, and the skimmate would be a very light, clear green. Why is my protein skimmer suddenly pulling out SO much skimmate?
