Instant Ocean Hydrometer accuracy?

[kmbyrnes]

While researching my jump into reefing, it became clear that water parameters were crucial. I wasn't going to risk hundreds ( thousands ? ) of dollars in livestock for the cost of a bucket of salt.

Got the BRS with calibration fluid and have never looked back.

Yes, I still use it when mixing saltwater (use a digital refractometer for checking tanks). That said, I have the equipment and knowledge to make very precise calibration solutions.

I don't buy into the hype.

I asked in another thread, but not sure if ill hear a response, but is it possible that the IO hydrometers are calibrated with the IO salts they sell too?

It might not seem like a big thing, but have you ever put the wrong fluid in a transmission before? yea...

maybe there salts have a different effect on hydrometer/refrac readings than other stuff?

just an abstract thought....

I've seen plenty enough threads pointing this out as a sometimes accurate, most of the time not tool.
A reefracto is about $40
For what I have in animals and time invested it seems silly to cheap out on such a basic tool need.

i think it is even wiser to use both? if they sync great! if they are both far off from each other then you got a problem somewhere LOL

you could never have too many clocks =P
