I agree I cant see how the voltage is climbing into your tank after everything was unplugged from the power bar. That said always invest in a decent power bar, even if its just for the computer stuff. The cheap 10 buck Canadian tire special have always creeped me out.

Take your time on the tank, figure out over the next bit what it is you want to keep in the tank. Look at others tanks to get a feel on size and what can be done in them. For example I have a 180G in my house right now that may be the I use to setup my "dream" tank or may not. Its 7feet long which I like, and 20" high so its nice and shallow. Issue for me is it is 2 feet deep (width), which is bigger than any other tank Ive ever had by a long shot... but it may not be deep enough for the aquascaping idea I have. 3 feet would be mucho better. But we will see as building a tank adds a bit more cost then buying used off here (which is where I got my 7 footer from). There are some unreal build threads on canreef here, as well as reef central. Spend the next months reading through peoples builds to get ideas, and avoid issues by living vicariously through their mistakes.
