I have a thick brown sludge growing on top the cube, living?? Cannot get a pic. Vert lights ruin photos. I am cleaning it up with a spoon and flushing it, I have covered with panda, it seems to be helping. is this gonna be an issue later? I am flushing weekly so any runoff should not be an issue. But will this schmutz rot or cause root issues in the cube?
