namely, me. I cannot believe I was so stupid as to go off and leave running water unattended. I was topping off my indoor pond (really in an attached sunroom/porch) This usually takes about 10 minutes or so to do with the hose I use. Well, I decided to test some saltwater tanks while this was going on...got some unexpected readings and then decided to test further...then thought I would feed the dog...came in here to check the computer and can you see where I am going with this?? I totally forgot the *&^%$ hose for about an hour. I went into the kitchen and had silt halfway across the floor. The pond has had a major water change and I have had a huge mess to clean up..unbelievably stupid error.
