That shows my progress with the tank from day one till pretty much now
Nice looks similar to my tank when I first started it.
Not sure if anyone suggested it yet, but outdoor landscaping yards are a great place to get tons of flat type rock (slate, etc) really really cheap. When we moved about 3 years ago, I switched the gravel to black, I liked it but I think I liked the light sand with dark rocks and a dark background.
Tank is looking good.
