I have a new Coralife Deep Six hydrometer that I've been using for the
past year or so. But over the weekend I sorted through my trash can
full of aquarium supplies, and found my old "The Original" Seatest
hydrometer that I've had for probably 20 years.
The Coralife reads 1.022, and the tank has been doing fine.
The Seatest reads off the scale, well above 1.027! It's pretty simple,
I don't see how it could have gotten screwed up sitting in a box? And
my tanks did fine 20 years ago too.
I'm going to take them both to the fish store and see what they say,
but which one do I believe?
