Here's something, I wonder if this stuff as actually an Iron fueled algae, as many of us stated that it appeared after using GFO and it's been speculated that GFO may introduce soluble iron into our systems.
Just from my own observations with it, I increased the amount of GFO I was using to get rid of it from 12tbsp to 16tbsp and it seemed like it's just gotten worse.
I have not seen my astraea or blue legged hermits eat too much of it, although a few times I think I might've caught some of my blue leggeds munching on it, not sure.
Although I might have a light CUC, 3 astraea snails, maybe 15ish or so blue leggeds, 4 - 6 nassarius snails, 1 peppermint shrimp and 1 cleaner shrimp in a 46g. Thinking about getting about 2 more astraea snails, 5 -10 more blue legs, and maybe like 25 cerith snails to see if it'll help. Does that sound like an adequate CUC for my 46g?
