I so know how you feel, I am not trying to hi-jack your thread but I understand your frustrations and sorrow, I went to bed one night all was well or so I thought, woke up the next morning, walked into the room to look at one of my tanks, coral's that I had had for 8-10 years, All Dead. I'm still at a lose to the cause. Just a few months prior, heater & timer melt down on another tank, lost 90% in that tank, at least I knew what caused their death, the other, still a mystery.
No matter what the cause, when you lose critters it hurts big time not just financially! I seriously hope you get things worked out. Your determination speaks volumes, you haven't thrown in the towel which provides others strength to pick up the pieces to begin again.
