Please tell me it has cycled.

Ok, scratch that, I do have time today. But how do I know if I have columnaris growing in it??? There's a cloudy mold growing on some of the rocks!

That cloudy, furry, stringy growth is likely Saprolegnia mold growing on the rotting fishfood. It looks a little like Columnaris, but it's not.

Vacuum thoroughly. You won't lose your cycle now that the filter is cycled.

Ok, tank has been vacuumed... let's hope I didn't screw something up. I had to add more water in order to get all the gunk out. Took the plants out for now, and rinsed the filter cartridge (which was VERY green) in the old water. Hope to add a fish tomorrow.
