@Mjrenz yes I did the hypo. I liked it so much that I have incorporated it as part of every new quarantine. I took them down over a period of just a couple hours. Going down does not seem to be a problem in salinity. Going back up I did take it slow taking almost a week to get it back to the 1.026. I did not use other medications in the tank while in hypo.
There are tests that are out there to show that the flukes die quickly and the eggs are no longer viable after five days.
I suggest using two different types of refractometers to make sure you hold at 1.009. Check pH But I did not have a problem and never needed to add anything to raise it.
I use the 1.009 as evaporation would raise it a little bit and I want to be sure to stay at or below 1.011 use the 1.009 as evaporation would raise it a little bit and I want to be sure to stay at or below 1.011
