Share 'Help needed with a Mediterranean'

So, the lava was fried in mine when I got it.  No matter how much I shook the bastard up, I couldn't fix it.  I refilled it with glitter from a Link'd globe.  Time to try lava again with material from the Five Below lamps.  Can someone possible let me know how tall the wax column is in their Mediterranean at rest?  Inches or centimeters are fine; my ruler has both on it (special ruler).
