I don't know of a test that measures a result of 5-7 nitrates... What test are you using?
The algae is likely diatom algae. It's common in new tanks, and since you keep changing the filter media and disrupting the cycle, it's like starting a new tank every month.
The bulbs in your tank will encourage algae growth. I agree with Cliff's recommendation of lights.
You've also been given some good plant recommendations, although I don't believe dwarf hairgrass will carpet without CO2 and fertilizer.

I suppose I could just say less than 10 since the color is lighter than the color for 10 but a bit darker than the color for 5.
I think the algae is the diatom. It comes off pretty easily although not completely. I have been getting conflicting advice on the filter pads in these HOB filters. Some say to change them monthly and others, like you, say not to change them. So I will try the easier way and not change them....just keep an eye on them and rinse them when they get dirty. My question would be does the carbon in these filter pads ever "wear out"?
Thanks for the info. I am really not interested in this time to have a totally covered tank with plants of all kinds. Maybe down the road when I feel more comfortable with knowing I can actually grow plants in the tank. So the carpet grass is not something I would go for at this time.

The carbon is not there to filter your tank. Its great at removing medicines and impurities in the water but its not common use in FW tanks. Leave it in there and let it be used for a surface for biological bacteria to grow. You need to read up on the free ebook on the left side of the main forum and you need to learn about the nitrogen cycle. Many great refs on this site.FW: 1 45gal, 1 40gal, 3 10gal, 3 30gal all community tanks of different species
