Tall Skimmer Cup, Small Tank Stand? No sweat!

My protein skimmer's collection cup is impossible to remove from my stand without tilting. This presents a problem when the skimmer is filled with skimmate; tilting the cup will dump the skimmate back into the sump.

Luckily, my skimmer's collection cup has a drain hole with a nipple fitting to connect to 1/2" vinyl tubing. I found some spare parts, and rigged up a piece of tubing and a ball valve. This should allow me to drain most of the skimmate from the collection cup, allowing me to remove the collection  cup for cleaning without spilling any of the dissolved organic stuff my skimmer has worked so hard to remove.
