I've had my 75g AGA with internal overflow running for about 4 months now and the overflow is filthy. How often am I supposed to clean it? Its full of bubble algae and red slime algae but my tank doesn't have any of that stuff growing in it. Both internal and external flow tubes are covered in crud as well.

Just wondering if this is normal.

Thanks,

Nick
