Actually this is my buddies 30gal showing a slight, er, problem with corraline. It's maybe 6months in this picture since the introduction of a single seeder rock.
Lighting - single 50/50 PC
, with an additonal actinic tube I haven't verified type as of yet. Might be a T5.
Water parameters are unknown. He changes 30percent of his water every other week, does *not* use RO
, and uses no other additives - I'm not kidding. The bottom of the tank has the densest infestation of shrooms
I've ever seen and you'd need a chisel to clear the power heads of corraline. Maybe there's something to be said about city water, eh? I sure don't get it.
