So, ... there you go and are.
You got the idea now. The bands keep the glass safe, or at least attempt to do that.
They also sell silicon bands for like a buck or few to do the same. I normally keep my
naked glass tanks here by the computer / television on the table. They don't go out when I go for
walk around/about. I'll use my aluminum
dressed Pyrex tanks, the AROs & T-Dux2/3s, RGM2s for going out.
Figure ~2/3 ml is all I need to hold until returning home. Besides that I think at most I pay ~$7 for one of the
dressed tanks. Now, the T-Dux 4.0 costs ~$7 as well and is short, I've been taking it out a little. Ultimately though, not too horrid to damage a $7 tank opposed to a ~$20 - $40 one.
Guess if you've got it and want to waste the bucks, doesn't matter and you'll carry a $$$ tank around everywhere. Some of us find that money stuff a bit rougher to see fly out the door. Nothing wrong being in either camp, merely observing the what is of what is. *chuckles* "Oh look, here is the obvious."
Apologies if that reads a bit sarcastic, or
smart, snide. Not really trying to write it as such. Sometimes though, no other way to express things exists. Even in what little writing I do, I note words can get in the way of words, or what is trying to be expressed. It is intended in general good humor and without what some call
attitude. I'm just writing it as chipper as able.
