I have a 40 gallon angel/community tank. I have always had an alage problem in the tank, but recently got it under control. But then this fiberous mater started to be everywhere in the tank (see photo). It is not very noticble from a distance, and from a distance only a slight haze. But up close, we can see lots of fibers. Is this from my filter matter, a plant, something else? Water paramters are fine.
The picture makes it look worse than it is with normal eye at a bit of a distance.
