Help! Fluval Ebi Glass Top Broken!

[TexSun]

I was doing some maint. on my fluval ebi, when I accidentally stepped on the glass top. The top is about 2/3 broken, so its trash.
Now I need to get a replacement glass top.... any suggestions?
I don't think its special glass, but the dimensions & cuts/holes might be tough.

Also, I have a 20g long that's been in the garage for a few years. Is it best just test with water and go from there?

Thanks

Rob
