How to tell if a red macro algae is growing?
This is a pretty simply question, how can you often tell whether a red macro is growing? I have some Bryothamnion where there tips were all fluorescent when I got it from live-plants.com. Slowly over a couple of days, the tips when from being really bright orange under my actinics, to more a faded fluorescent. And today I noticed that all the tips have turned a bit clear. Things is I cant tell if that is a sign of growth or death. Thats because other plants that I have are clearly growing, like a Rhipocephalus phoenix, codium, and some halimeda.
I tend to feed pretty heavy and my nitrates have been between 10 to 20 ppm. Calcium is 450 to 500 ppm and Alk is between 8 to 11 dKh. I've also added some Kent Marine Iron and Manganese Plant Supplement and the Iodine supplement as well. Aside from lighting and flow, I'm not sure what else to adjust. |

I'm pretty sure the color change means it's dying back. If you have plenty of nutrients, try moving it into slightly dimmer light. None of us can grow everything. We try a lot and some survives.

Bryothamnion does not like very bright light. It is used in DT at the base of the rock
