Hi, I have a built in corner filter in my tank, the tank is about 2 months old.
Its been growing brown algae on the glass.
Im not sure what i can do about it.
I was hoping it would grow enough so that it looks black and doesn't let light in.
Would this be ok to have permanent brown algae in the filter.
Another option i thought of is to paint the outside of the tank where the filter is, I wouldn't be able to paint the inside really though so some light would still be able to get in.
I've included a picture below.
Anyone had this problem before?
I know the filter i have is a bit different, not sure why they've used clear glass.
Any help would be most appreciated.
