This is just a stub for now. I took a quick picture of my 20L the other day so I thought I'd post it.
I will switch the 20L tank to a 29g tank when I move in a few weeks. For now, the 20L is in horrible condition. No CO2 or ferts. No scape. Just a few plants and lots of GSA.
I have a lot of work I want to do with this tank. It'll be fun to see the transformation from what it is now to what I hope for it to become.
My 20L tank's very humble beginnings.
