Tank crash

[isaac1]

Hi about 2 months ago when I was working out of town I got a call from my wife telling me everything was eaither dead or dieing she described it as everything was crawling out from under the rocks and dieing I lost 2 clowns a coral buety half a dozen crabs and well over a hundred amphipods but to my supprised when I came back and finally got a chance to exam the tank I noticed all my corals were fine and doing great as well as a hermit crab that hangs out on the top of my life rock ( all my corals are placed mid to high in my tank) I have no explanation for the loss water peramiters were all within range so after doing numerous water changes and battling red slime algie for the past month I decide to take a gamble and add two chromis to the tank as a test project if any one has ever had the same thing happen or any ideas or clues to what have might caused this I will appreciate all feed back

Its hard to say without more information. Age of the system, equipment, water parameters, pictures etc would certainly help.

Sounds odd, is there any chance that there was a large temperature swing?

Oxygen?

Negitive on the tempature swing and I've never moved my rocks around I was thinking it might have been a dead spot pocket built up under the rocks but I would think if it was my corals and hermit would have died

did you add any fish to your tank right before this happened?

[isaac1]

Negitive but I did buy the two chromis and frog spawn off u yesterday lol

The only thing out of the ordinary that I noticed was about a week before the coral beauty came down with ich pretty bad for about 3 days out of the blue but I've delta with ich tons of times so I don't think it was that
