Tank crashes: causes, treatment and lessons to learn.

[neoh]

I have several anemones, and I covered the powerheads in a nylon netting, so hopefully that helps.

Even though my bta seems to be liking the bottom of the rocks as of late.. much the the shegrin of the hosting clown.

• Introducing Atlantic Blue tang and getting Marine Velvet as a "bonus".
• Clams spawning and turning tank into white cloudy, stinky mess.
• Holding live rock for someone as a favour and it turns out to have hair algae/aiptasia which then spreads to your display tank.
• Keeping too many "ick magnet" fish in the same tank.
• Bad salt (anybody remember the Kent salt disaster?)
• Having a boxfish or cowfish or large sea cucumber die and wipe out the tank.
• Relying on an undependable (i.e. stupid) fish-sitter while you're on vacation.
• Having visitors with kids who dump a whole container of food into your tank.
