The clean up crew had the clown and shrimp that were visible completely eaten in a matter of 4 or 5 hours. I've tested everday and have yet to detect any amonia at all.

The pumps would have only been off for a couple of hours. I've had the pumps shut off for a short time like that without anything dying. If the power had gone off, the clocks and stuff around the house would have been off. Everything was normal when I woke up Sunday morning.

My friend keeps saying that he thinks it was an electrical surge that killed them, but I just don't believe it. The electricity would have killed all my shrimp and other clean up crew too, wouldn't it?
