looking for answers to why my Gracilaria is turning translucent colors and soft and brittle. I've had them for about a week and a half and they are normally dark reddish-brown. I just use it for refugium algae. What's going on?
I just took a nitrate test yesterday and it tested at about 25-30ppm. I also am running a 60W CF at 5500K for 12+ hours at night. Should I change anything? Do they need to be rooted on a rock or in a sand bed? Is free floating ok?
