Over a week ago I mounted a few frags with epoxy. Three frags, and didn’t use a lot of epoxy. The skimmer started bubbling like crazy which I was expecting. But I didn’t expect it to be doing it a week later. Yesterday I remounted the frags with Tunze coral gum and did a small water change mostly with water pumping out through the skimmer cup. Nothing has changed. I took it apart twice and cleaned it. The only thing I was able to do was to restrict air intake and that kept it from overflowing inside the cup.
Just wondering what’s going on. At this point, I’m not sure it’s due to the epoxy.
