I made some significant changes over the last couple days. I moved from 2 halides down to one, did a 30% water change, added bacteria, and turned my skimmer off. Everything looks 100% better.How often are you doing water changes? I've read - or perhaps watched on YouTube- that Protein skimmers can take out helpful things like trace elements and such as well as taking out the bad things. A once a week partial water change of about 5 - 10 percent is the most recommended cure for this skimmer-related issue. On YouTube there's a channel called "Tidel Gardens" who is one of my first go-to's for everything. He's a HUGE advocate of "water changes cure all."
I was starting to think the same thing. I wonder if my skimmer was pulling out all the nutrients in a newer tank and causing stress??
