SALTWATER FISH TANK AND OIL

Question
I have a Salt Water Fish Tank recently at a party, my diffuser oil was tipped over and went into the fish tank killing all the fish.  What do I have to do to reuse all the equipt?  The tank is less than a year old.  Please advise  Would this be covered by homeowners?

Answer
well i would not use any of the equipment because oil went through everything so buy all new everything just clean the tank out real good with just water but get new filters,heater,gravel everything so the tank has nothing in it and clean the tank out real good with just water and you should be good to go
