I am SO sorry to hear about all of these strange losses... it's obvious that you are extremely frustrated (and with good reason), but please don't give up. You've got so much invested in your tank (not only the money), and it would be a shame to just walk away from all that.

I wish I could give some advice on what might be happening, but I'm still too new at this to be of much help. Hopefully, some other folks can help you track down the problem. I just wanted to let you know that you've got lots of people here who care and will stick with you when things are going badly. :color:

Hugs!
