So I glued down a frag (with the stem snipped off) to a rock the other day, using ecotech glue.
It wasn't getting enough flow so I pooped it off the rock to move it and I saw this red crap between the plug and the glue I put down. It was NOT there when I glued it down a few days ago, and this stuff almost looks like rust but it is a brighter red color. I see no movement of any organisms.
Now I have encountered this before and I had just figured maybe I had missed something, like maybe it was there before I mounted the disc, but this time I am 100% sure it wasn't there. It is between the ceramic disc and the glue I put on, it hasn't gone anywhere else. What could this be?
