3.8 WPG on a 10G tank. Are you using the spiral 19W bulbs? If so, then you are having less than 3.8 WPG.
Nitrogen has been traditionally used to promote vegetative growth and intensify the green coloration. You can add as much micronutrients (or nitrogen for that matter) as you would like, but with that much light and no CO2, it won't help your current condition any.
It is odd that your water company doesn't state the elements. What elements/compounds do they state? Let me know where you are from and I'll see if I can find a water quality report for your town or help you interpret yours. If you can scan/transcribe the report and/or provide me with the phone number to your water department (should be on your utility bill), then it would expedite my search process.

I see you post a lot across the various forums. A very admirable trait by the way. I am glad that you are asking questions. But to avoid confusion and localize information, let's take a look at your setup across the board. Would you please describe your current setup (both hardware and flora/fauna) in
as much detail as possible for me please? Let's work through this together and get everything in order. :biggrin:
Having a successful planted tank is quite easy and methodical. The real challenge is getting the necessary funds to purchase the raw materials. Let's see if we can't save you a few bucks without sacrificing outcome.
