Advice On Refractometer

[Ian H]

Going to be buying a nano tank next month for a nano reef set up, never had marines before so everything is new to me. Is this refractometer ok:

or is it going to be really cheap and nasty? says its got a scale from 1.000 to 1.070 which is fine as i want 1.023 - 1.025 right?

Any cheap s#!? off Ebay will be fine, provided you calibrate it with liquid of a known salinity, very close to the levels you are looking to test for Basically, read the realm of knowlage sticky and look for the DIY refractometer calibration standard fluid. The salinity you want in the tank will depend on if you keep corals or not. With corals, you want to aim for 1.025-1.027, for fish only, 1.023-1.025 will be fine

All the best

Agree with rabbut, calibrate it with a known cal solution and you'll be fine

Assuming that will be fine then if any old #### off ebay is ok? refractometer for under £20 sounds good to me

bought

Although it does make me doubt the build quality when it comes with a spare daylight cover

Meh, it'll be right Just so long as it doesn't fall apart in your hands. It's cheaper to loose than a shop bought one.
