Yes I will definately be using a sponge filter next time even if purely backup. I won't be leaving the tank without any air after that experience, but at least I was able to save most of them. It would have been tough to get them this far and then lose them to an equipment mishap.

Sorry your having trouble! How many fry would you estimate that you have as of right now? said:
My last estimate was around 150 so after the 15 deaths I would say maybe 135ish. That is an extremely rough estimate. They move fast and like to swim in giant balls of fish so it is nearly impossible to establish a decent guess.
Thanks everyone for the concern and hopefully anyone thinking of doing this for themselves will learn from my mistakes and it will prevent them from having the same troubles. After all that is exactly what this was created for, to see what really happens good and bad.
