Odd "fuzz" in my luwigia - need ID
I did a water change yesterday in my PFR tank, and about 12 hours later I notice this "fuzz". I tried to take a pic but it didn't really work cuz I'm a newb.
The ludwigia arcuata is from PetSmart, and it's doubled its size since I bought it, just starting to get needle leaves and turn red, problem is there's algae in it, if you can imagine the ludwigia stems as a bamboo forest it appears there is some translucent mist or fog in it. Strangely this stuff doesn't exist in any other parts of the tank.
How I feel about non-planted aquariums.
