Feb 11 Update (unfortunately not a good one):

A week ago Monday I went to empty the skimmer cup and when I grabbed the body of the skimmer with my left hand I came into contact with the water and got an electrical shock. It was late and the main lights were already off but I could see that some of the corals didn't look good. I immediately turned everything off, then grabbed my multimeter and started plugging things in one at a time. It turns out the return pump was the culprit, it was putting around 35VAC into the tank. Some of the acros and the purple pocillipora didn't look good but everything else seemed to be alright.

Work was extremely busy last week so I wasn't able to get out and buy a new return pump until Sunday. Since I didn't want to keep the bad pump online I let the tank run with only the nanostream on for circulation. I only fed lightly once, I believe it was on Thursday...

Surprisingly, the fish seem like they're doing fine. Most of the corals seem like they will make it as well, but two of the acros have bleached significantly and I don't think will survive. Other than the two acros the biggest problem is that the small amount of bubble algae that I had in the tank previously has increased dramatically in those few days that the filtration was offline. I did a water change on Sunday and hope that with a few more water changes I can get it back under control.

I have never had a problem with electrical components previously, so I hadn't put a grounding probe on the tank but I am going to order one this week just in case anything else ever goes bad.
