I built a frag rack and it is right beside my overflow to reduce the chances of contamination. This head seems infected too. I was able to pippette the secretion easily on the rack.
I started the tank in november and i only test nitrate arround 10 and alk arround 8dkh. I dont mind what level they are, i want them stable and i do 2gallon change every week.
I think my parameters are not a problem, but new rocks may be leaching stuff.
Heres a picture of yesterday. I orderd some chemiclean, i will use it for the cyano and it might help with the jelly.
Here is the duncan before and after being pippette. I think that the black dots are dead tissus from the peroxyde. Its only on the tip of the tentacles.
