I use a lot of tank crackers so I end up using full SS tanks on my RTAs (e.g., Aqua V2, Orchid V4, etc.). 
Other than buying glass tank RTAs, which of course I already have, does anyone have any good tricks to tell you when your tanks are low with SS?
I hate that last dry hit telling me its time to fill up.
