Cloudy glass / mineral buildup / vinegar doesn't work
My 110 tank has a glass brace in the center, was used when I got it. The brace is pretty cloudy with what looks like mineral buildup, and when I first got the tank I soaked and scrubbed with a razor it for a few days with no visible progress in clearing it up.
I've sort of lived with it to date but I notice the plants directly below the brace don't grow quite as much as the rest. Is there anything else I can try? I have some glass stovetop cleaner I might give a shot... Just need to figure out some way of preventing any from landing in my tank.
