I the past 3 days there is something all over the plants in the tank, i can only descripe it is small bits of brown fuzz they are all over every plant in the tank, and bits are wafting around the tank. I am not sure if this is a common problem or if anyone even knows anything about it. The water seems to be very clear, and the fish quite happy, i am going to do a full water test tonight to see if that can give any answers. I will post any unusual results tonight. Hopefully someone will be able to help me on this one.
