hey thanks for all the responses guys... lets start with a few notes...
I do not use a heater, well in the summer at least... the last one i had blew anyway as it came in contact with air, un-beknown to me... now that was a shock lol...
i wouldnt think its the power strips as i use American DJ strips and they are made heavy duty, and made very well... but i guess i'll have to learn a bit more about them...
it could definately be one of the two koralias in my 65g "fuge"... they are the old, original models, so they are at least 4 years old... they are currently unplugged and i dont feel anything... well a little sting in a small cut on my finger, but i think that is jus the saltwater hitting it lol...
my light is actually hanging from the ceiling and none of it is in contact with my tank or plumbing etc... so i dont think this would be it... but worth a mention none the less, ty...
**************
at the moment, i have my skimmer offline as it has 2 pumps, i have both of the older koralias offline, as well as the coralife power center that was powering the Koralias (i need another DJ strip for that section of my system)... i what i think i will do, is plug in one item at a time and see if any of them cause a shock... i'll start with that, and go from there...
i really hope its not a skimmer pump, as i dont have the loot right now to purchase new ones, nor do i have a second skimmer... though i have been meaning to get new pumps for a while now, but the ones i want are gonna run me at least 400 bones lol...
i'll check out some things here now, and post back if i find anything...
thanks again guys! any and all input is ALWAYS APPRECIATED
