How long has this tank been set up?

Where did you get the lava rock from & how did you prepare it for the tank?
 
I had lava rocks in my canister filter for a long time as a biofilter and had no deaths.

Unless you put in contaminated lava rock I can't see this as a cause.
 
did you clean the lava rocks before putting them in the tank?
