Hello all, I'm mostly a lurker but thought I would share experience I had that could have resulted in a total loss of my 120 SPS tank and how I prevented it for around $70. I had a 10 day vacation scheduled to Mexico and decided to buy a wireless camera to stick in my sump mainly to monitor my skimmer to make sure if it overflowed I could let my dog sitter know to empty it. The day after we left (flew to KC first to visit family) I checked the cam and noticed the skimmer was overflowing, at around 1am no less. The next morning I looked again and noticed the water level in the sump looked high and could tell the water movement looked stagnant....checked a little later and looked high but like it was flowing? Checked my apex and noticed the fan was on causing the surface movement of the water. Then I knew the return intake was either clogged or had failed....I have never had anyone service my tank and the dog sitter certainly wasn't experienced enough to trouble shoot or repair so I was debating flying back to Chicago, fixing and hopping back on a flight to KC but that could have left the tank without heat for nearly 20hrs. At this point I was accepting defeat and my wife asked if the camera ended up just making it worst knowing what was happening without anything I could do about it. On a whim I remembered Beyond the Reef serviced tanks and gave them a call as soon as the opened (on a Sat). They said they could check it out in a hour or so, faxed a CC authorization form to them, and fortunately I had a backup pump at the house so I called out dog sitter, had them meet the Beyond the Reef at the house....and was able to sit in my hotel room and watch (Derek) change out the pump from my phone. If you ever have to travel and want a little bit of piece of mind....I would highly recommend getting a wireless IP camera to monitor your sump....as it saved my tank and a huge mess. I have a apex but my thermometer is in the sump so that alone would have done nothing to prevent this incident. Hope this might help the next guy to avoid potential disaster.
