Hang in there oddsox, it can be done! It would be help to have details regarding your tank - how much lighting, do you fertilize, water params (hardness, etc) - to provide with more to the point type answers. From what you describe, your plants are not getting what they need to thrive. I assume your tank has cycled.
If you have hard water, you will get white crud on your top over time. I have hard water, and I use a razor blade to scrape my top (just a piece of glass that sits on the tank and holds the lights), periodically. It does eventually get some scratches, and is not perfectly clear, but it does its job. If it ever got to the point where it needed replacement, it's cheap enough to have a new piece of glass cut out and placed on the top.
Hang in there, it can be much better!

Yes, and no. I can only speak for my tanks, and in my 50's, except for a little gsa and gda, I do not have algae. Plants are healthy, but I know that certain plants will not thrive in my water and tank conditions, and I don't try to force the issue. I also have a 10 which I am currently battling bga, and a lot of other issues, because I changed some things and didn't think it out properly to start.
