I just trimmed my chaeto, but I tend to throw out about a shopping bag’s worth every few weeks. I do have aiptasia and bristleworms in my tank, so there’s that risk, but if anyone wants it/doesn’t mind cleaning it up, let me know! There also might be pineapple sponges, mini brittle/serpent stars, (reef safe) Asterina stars, pods, etc. in there.
I’m on Vashon Island.
