I have this 45ltr tank run with a sponge filter, and plants grown in, but getting this odd white feathery stuff on the glass, and on the substrate. Also some brown mulm that is only on the substrate, and is thick with it.
Any ideas? was thinking the white stuff might be a fungi of sorts, brown stuff covering the substrate not too sure. It vacuums up easy enough.
