So did you do some water changes to bring the tin down? Did the Tin actually cause some corals to die?
Hit it from a few different angles, including water changes, cuprisorb, panta lite and detox.
A few things died and a ton of stuff lost its color but things turned around when my triton started reading 0 on tin again, and since that was the only thing odd on triton and I haven’t changed lights or flow it just made sense through elimination.
