Do I need to worry. Our new ten gallon been up and planted since haloween. I have had a bit of trouble with some thread alge on my moss. And today when I changed water in the tank I noticed some brown spots on the back glass of the tank. I reduced the length of time our light is on to seven hours this week to see if it would help with the thread alge problem. Not sure if the brown spots where there before I reduced the lenght of time the light is on. Suggestions would be great.
