Man. I gotta tell you. With all that gear. All that experience and all of today’s resources. And your having what I would call a fairly serious issue. Sometimes it makes me feel like I don’t have a chance. Maybe I should have made a terrarium
Mags what you’re describing has happened to me before. Shrooms and zoas/palys shrinking and melting. Mind you this happened while other shrooms and zoas/palys have stayed at perfect health at the same time. i have my sump grounded, there are zero cords in my display. It’s was extremely frustrating, and I’m afraid I may never know what the cause was.
Same thing happened to me when I had my Mini crash over the last couple months I did a bunch of water changes and the tank is back on track now. All my parameters were good icp test came back good. I never figured out what happened.
