I've noticed brown spots on my silk plants.... and also on my inside walls of the tank... I was thinking algae.. but I don't know? When I brush the walls with the algae brush last night it all came off... but this morning there was more... and it looks like there is more and more growing, or more like appearing on the plants...
Any ideas on what it might be? Or how I can get rid of it?
