One of my friends is doing a presentation on corraline algae at a local fish club. I told him I'd ask if anybody had any input on it on here....
I was curious when people started to notice corraline on the backs of their tanks(from the time of setup), along with what your typical water parameters were(calcium specifically), and lighting, and if you added any supplements.
Mine was 5 weeks from setup, with PC lighting; no supplements. Water temp average 81 degrees. 8.2 Ph, my calcium has been around 460 ppm
