HELP! Fatality after Fatality with practically any new fish. Brook or Ich or...?

Curious - which test kits are you using?

Hanna Instrument Checkers.

Hanna Instrument Checkers.

Awesome - now we've ruled out something. That said - can you give more information - did you get your fish from the same place - did you QT them, did you treat them? Did you leave the tank fallow for let's say 76 or so days - before adding new fish? Are you using RODI water? Is there any other toxin in the room (I discount this - as well as stray voltage) ?

That's Brooklynella. You can try Ruby Reef Rally Pro, but that doesn't always work. There really isn't any other treatment you can use in a display tank.

Rally Pro has worked well for me, as a bath before entering quarantine. And for those in the US who want to keep some straight formalin on hand, try: Amazon product
