wow, tons of good info in that thread.
so my gramma's spots are almost all but gone today, but he's still scratching.
He isn't hiding any more tho and he's eating, hopefully this isnt just the lifecycle of the parasite and he's actually improving.
i cleaned my hydrometer and "seasoned" the needle over night, cleaned it again, then tested this afternoon... reads a bit lower, hopefully more accurate. Says 1.026 (before was ~1.027)
time to track down a refractometer to make certain and reduce the salt content.....
