On behalf of Knight~Rider,

I noticed at first there were brown spots on the filter which looked like rust.
I never did anything about it as I never thought anything about it.
Now the spots seem to be growing on the glass of the tank. Why is this? and what should I do about it.

I have had the tank for about 2 months with 10 fish in there, the water is clear they all seem to be doing well. Dohank es this mean I need to do a 20 percent water change?

Is it normal when I open the lid that the water smells?

Thank-you,

Knight~Rider
