Terrarium Tank Suggestion - Scratched Glass

[TheFreshman]

Hello:

I'm new to this...forum, terrariums, gardening, the whole bit; so you'll have to excuse my ignorance.

Since I'm not permitted to have pets in my apartment (including fish) I've decided to grow plants. The more I searched the internet, the more I began to like the idea of having a terrarium. I originally thought I'd purchase an eXo kit, but then decided to put my craftiness to work and bought a used 90g tank today!

I thought I checked the glass thoroughly when picking it up, but after a few hours of cleaning and sanitizing I found that my attention to detail was sub par.

Is a tank with scratches something I will surely regret after I get it set up and viewable? I would hate to have wasted half my day cleaning something I'm not going to use and deal with reselling it; but I also don't want to put countless hours into something that won't be appealing. Thoughts?

Thanks in advance!
