Well I work near my home on somedays and just happened to stop in for lunch, as soon as I walked in the door I smelled burnt plastic and heard sloshing water fearing the worst was happening I rushed into my living room to find water at my feet and the surge protector sparking and smoking. I wasnt smart enough to think before I acted ( hum water and electicity ) not a good combo but I guess I got lucky cause I didnt get shocked and managed to unplug everything. only one of my breakers had poped and the surge protector did not even flip I am so lucky I got home when I did, the protien (cpr bakpak) skimmer had a modified maxi 1200 instead of the rio 600 it came with and had been working fine for months untill the air feed fell into the water and the over flow hole became blocked and at a rate of 1200gph water started to spew air born out of my tank on to all of the electric and into the basement (unreal) by the time I had arrived it had emptied almost all of the water to the bottom of the pump approx 15 to 20 gallons in a 125 just enough to expose the tops of my coral. all I can say is even though all of this happened I was very lucky and just thought I would share my near disaster story. all is fine now
