Chaeto reactor not doing so well.
I have had this chaeto reactor running for 2 weeks now on a month cycled tank and have had noticeable growth - maybe doubled in volume from the baseball size it was.
But now I am seeing some brown growth on top of the chaeto which was once bright green (see below) and on the acrylic. Some of the chaeto is even becoming pale, just look closely at the photos.
I am guessing this is some cyano or diatom that is covering the chaeto and blocking light and/or respiration .
I have very high nutrient levels and I run the lights 24/7. Running the lights 24/7 should not be a problem as I have seen many do this with macro reactors with no issues and great growth. It seems to just be stunted by this brown growth. Or maybe that is not what haa stunted it, I do not know.
Any tips?
