Portable RefractometerEasy & very convenient to use High Quality, Accurate testing Range 0 10% Salinity. What does a refractometer do? Serious hobbyists know that the best way to measure the salinity and specific gravity of aquarium water is to use a refractometer. These precision optical instruments are incredibly accurate even at very low salt levels, and are equally easy to use. Recently, these instruments have become more affordable, so now every aquarium owner can

Delicate components like unsaturated fatty acids often get damaged during processing of fish food

the reduction in the magnesium or calcium concentration caused partly by cellular metabolism and partly by skeleton formation means it is necessary to test the concentration levels on a regular basis and
