Tropic Marin hydrometer

Gotcha. I have also heard someone say that their paper moved so it wasn't accurate anymore. But mine is very old and still spot on.

Yeah, again mine is not the TM brand so that was probably my issue

I need also cylinder right? The full pack

I shut off my return and circulation pumps and just test it in the tank. No need for a cylinder as long as your tank is deep enough.

That's what I use. The Milwaukee MA 887 for everyday use. I use the TM hydrometer when mixing up newly made saltwater and to verify the Milwaukee. Bought the 500 ml graduated cylinder on Amazon. You will need every bit of that 500 ml to use the TM hydrometer.
