I left the RO/DI going on the QT tank all day. Don't know how but I forgot to shut it off. I'm sure the water by now has no salt in it. What do I do with the fish? Can I use water from my tank and the re-treat them again? I'm such a moron.
Thats quite a FW dip. Go very slowly on bringing them up. Up is much harder on them than down or staying at a low salinity. Keep an eye on ph and maybe add a buffer.
