I hate to say it, but one of my sapphires is dripping out of its base. Up until now, there were no issues; it gave up on the last fill though. I thought it might have been a fluke so I drained what was left, cleaned it up, and refilled. Sure enough, it is leaking. Looks like I will get to dissect one sooner rather than later. Luckily, number two is still working like a champ.
