Lately I have noticed some sort of white gelatianous stuff (fungus maybe?) growing mostly on the leaves, rocks and wood in my tank. It seems to be on most of the live plants, but it sort of favors the swords. The plants seem healthy otherwise...
Any ideas what this could be? My tank has been running for over a year, and all the parameters are stable. I tried decreasing the light cycle down an hour to see if that would change anything but it didn't really.. The aquarium lights are on for 7 hours a day.. sometimes 8 at the most.
thanks in advance,
