I took about 80% of the rocks and peroxide and scrubbed the snot out of them they look better in going to combine this with lights out and a massive wc on friday
estimate there to be twenty or more anem documentations in that thread. It's not that I'd go off directly dosing every sebae and heteractis one could find...work around as needed. It's that accidental direct dosings are rarely lethal. We show a bunch of purposeful dosings there.
Do some research first, but from what I understand invertebrates are at risk, but if done slowly and methodically it is possible to dose the tank directly. His primary recommendation is to remove the rock and dip in H2O2 then place back in tank once rinsed. Not sure if that recommendation has changed. I've used this approach with good results.
