Sulfur oxide is to high. 😞 even R/O filter doesn’t clean it all

I saw a video on the best fish for a nano tank you all did. In the beginning it showed a 3.5 tank. I really liked the look of that tank. It was wider looking. Do you know what brand that was? I haven’t had a tank in 15 yrs as I’m on well water and it is no good for a normal sized tank. But 3.5 gal I could just use bottled water and I really miss a planted tank so I think nano is the way to go.
