Ultimate Reefer
That is not an aefw between the barnacles nor at the bottom of my container. These pictures were taken right after my bayer dip and I basted heavily. The circled spot is sad to say some "rust" from leaving a razor blade in container too long. I cannot get it off of the tupperware.
This piece has been in my system for about 4 months. I picked it up from a LFS. He kept a frag and his is doing fine, but as I mentioned, my tips started to lose color first, then PE loss, and now this weird stn.
Just double check; there appears to be a FW stuck on the bare skeleton: right between the two barnacles in the 2nd and 3rd photos.
If you are sure you haven't, then I'm pretty happy for you that its not AEFW's.
In that case, can you list all your parameters and everything you are using for filtration.
