keep the lights off.
I usually dont advocate using bacteria additives, but if you have some, use it... anything with Nitrosomonas, or Nitrobacter. (the nitrifying bacteria should deal with your ammonia problem, for the moment anyway)
ok, question time... detail all the filtration equipment you are using, how long has each item and tank been running??? have you recently done anything different???
aside from the suggestion above, do several small water changes every day... even if it is just a bucket at a time. Sounds like you are having a massive spike in your parameters... (have you tested for NitrItes, or NitrAtes?)
