I wanted to share a scary story about an event that happened earlier this week with my display tank. I will be posting this on a few fellow reefers threads to get the message out so bare with me if you see this post more than once. Earlier this week on Wednesday my wife came up from the basement which puts her in the dining room where my DT is located. When she entered the room she commented to me that she smelled something like a burning smell. I went to investigate, but was unable to find anything that would explain what she was smelling. While looking for the cause of the wife’s mystery odour, I did not smell a burning smell or anything so I figured it wasn’t anything to worry about. On Thursday morning I went into the basement to feed my FOWLR tank and take care of some minor maintenance issues. When I came back up stairs I smelled a burning odour this time and saw smoke filling the air. I started by looking under the tank stand where my aqua controller and my closed loop pump are located along with my MH ballasts. I found no problems. I looked on the rear of the canopy where the Icecap ballast and my ocean motions 4way are located and again no problems. Finally I opened the lid on my canopy and alas FIRE.....
The lights where all on, both 250W MH’s and two 110W VHO actinic, except one of the waterproof end caps for the VHO T12 actinic was burning and had started to spread to the wooden canopy. I couldn’t believe what I was seeing!!
I would have expected the GFI to pop if there was some sort of a short in the end cap but that never happened. It was so strange seeing half of the end cap engulfed in flames and melting, while the lights were still working. I safely put the fire out after unplugging the Icecap ballast that drives the 2 VHO bulbs.
I’m not really sure what caused the end cap to erupt into flames after 2 years of no issues but I feel that I may have bumped the bulb during some routine maintenance that may have slightly unseated the bulb prongs and this may have caused some arcing at the contact points in the end cap which created heat and ultimately caused the end cap to catch on fire. Thankfully I was at home when this happened or the results would have been disastrous. The fire would have spread for sure and I would be homeless now if it wasn’t for the luck of being home at the time.
I would like to say that I will never take my wife’s smoke smell comments for granted ever again even when I don’t smell it. She must have a better sniffer than I. I recommend that all my fellow reefers take a minute or two and check all your electrical connections for loose, frayed, salt creep covered, loose bulbs or anything else you can find out of the ordinary to hopefully prevent you from experiencing a similar scary fire.
