Refractometer?
Hey everyone,
Prepare for long winded question!
Bit new around here but my tanks been up about a year, when i first got it the shop sold me both a little thermometre which floats to tell you the salinity. Also got another thing for salinity where you fill it with water and a little arm moves to tell you the amount (not sure whats its called)
Apparently this has been a huge oversight on my part and I should be using a refractometre - just wondering if there's any recommendations on these? i also read they need to be calibrated after use??
Bit lost but there's some on ebay for around $30 and i figure they're all relatively the same aside it the more expensive ones being branded
what would be anyones thoughts on this?
Thanks :)
