LOL guess I won't have to bother with them then because the filter didn't come with the tank You guys have helped me a lot the only problem I have is a few scratches on the rio 125 I'm trying to remove which I've made a new topic on this in tropical discussion section. I'm going to empty it and try out a few things that I've researched and been told. Otherwise I am going to have to live with it
They are quite all over in small smudges looks like they are made in small circle movement maybe trying to clean something from this inside. However, its not too bad but once you put in the black background you can see them a bit more. Thats why I'm wanting to remove them.
