Has anyone here used any Tetra brand tanks? More specifically, has anyone had any major issues with one? Its very affordable as they come with everything, and I have an extra heater if the one it comes with is finicky. I can also baffle the filter if it's too strong. But I'd like to know if there are any major problems that cause it to be more stressful than anything or will lead to me spending as much money as not buying it in a kit or getting a bigger name, like TopFin, NatGeo, etc.
