The thrashing around comes when you fresh water dip the seahorse. It's a result of the parasites dying and trying to escape from the seahorse.
As for pH, I now use a hand held pH pen, but before that I just used a test kit.
It's just a matter of matching the colours of the salt tank to the fresh dip water.
After you first time it gets much easier once you know what to expect.
I panicked at first when after the thrashing stopped the seahorse began to lie on the bottom, but when I touched it with my finger it moved around for a bit and lay down again. I left it the full 12 minutes as it always moved when I touched it.
I've done this numerous times since and have not had a problem, but occasionally the seahorse doesn't move when touched so that's the time to remove it and place it back into salt water.
