I have a media rack in the 2nd chamber of my biocube-2nd tier has 2 small pieces of LR rubble and what used to be a larger then a golf ball size clump of chaeto which is light 8hrs a day with a 3w nano led.
Well the chaeto although still very green, is breaking up. Very small pieces at that. Is this normal? Should I remove the rubble pieces? Should I just replace the chaeto?
