Multi Reference by Fauna Marin is the first product of its kind that helps reefers really dial in their chemistry, by testing the tests. WhereTwo Little Fishies’ AccuraSea and Brightwell Aquatics’ Refractometer Calibration Standard are only references for salinity, and very important at that, as the name implies Multi Reference is a standard for more than just salinity.
Multi Reference is made not only with a known salinity concentration, but also a known level for calcium, magnesium, alkalinity and even a couple nutrients like phosphate and nitrate. The expected concentration from Fauna Marin Multi Reference are below:
- Calcium – 425 mg/L
- Magnesium – 1,315 mg/L
- Potassium – 375 mg/L
- Salinity – 33.9 ppt (51.6 mS) @ 75°F
- Alkalinity – 7 DKH (2.5 meq/L)
- Strontium – 7.1 mg/L
- Nitrate – 11.5 mg/L
- Phosphate – 0.05 mg/L
Fauna Marin’s Multi Reference is not going to get anyone out of their chairs with excitement but it truly is quite a useful tool for double checking both the accuracy of your test kits, and even your own methods for performing them. A 100ml bottle of Multi Reference costs only 10€ but the peace of mind it offers knowing that you can count on your test kits is much harder to put a price on. [Fauna Marin]
