Hyposalinity and Trigger

[Mikemilly245]

Just purchased this trigger , have it in a bucket to start acclimation.

Have a question , would it be possible to slowly decrease the salinity in the bucket with RO water over the course of a couple hours ? Then put him straight into a hypo QT setup at 1.010 ? Or how quickly can I lower to prevent shock

While fish can be reduced in salinity faster than they can be raised, that is a bit too fast. You can lower the salinity from full at 1.025 to 1.020 in a couple of hours, sometimes faster. I'm not sure that this is a constant scale though - most fish seemed more stressed as they make the later transitions to 1.009.

Here is my article on hyposalinity treatments:

Hyposalinity

Hyposalinity Jay Hemdal 2024 This term refers to a long-term bath treatment for marine fishes in which the salt content of the water is lowered and held below the point that certain parasites can survive. The salt level reached, and the time of the treatment are the two variables...

Hypo works well for marine ich and flukes. It will sometimes work on Brooklynella. It makes Uronema and Velvet worse though.....
