I set up a 45 that I had pick up used sunday and after 24 hrs of running it came up with a small leak around the bottom. so I tore it down and resealed it. then yesterday my wife put some corals into my frag still in there bags and left to go down town. I was out side on the tractor spreading rock on the driveway about 20 min later I went into the house to find a water fall coming out of my frag tank. the bag had made its way to the over flow return and plug it. 20 est. gal. of water on the living room rug. 4 hr later working with the shop vac. and all night with a box fan and its still not dry. now I have brought in my propane heater to help dry the rug. might be dry in 3 days. bags are gone corals look good and 45 is leak free. things are looking up. Thank God.
