I just stepped up to a vamo v2 yesterday from an ego twist. I love it. I had a vivi nova tank, so I decided to just stick with that for now. I have been looking at different tanks and what not. I am deciding what to get. I want a glass tank that will work with all my liquids. I have watched a few kranger protank reviews, and I am kinda leaning towards a protank. Does anyone have any other suggestions?
