Instant salinity reading
Salinity is a general term to describe the concentration of salt in water. However, there are always different salt content in the solution which is also known as different refractive indexes (salinity readings).
Dymax RF-20 Refractometer is a scale device that helps to read salinity of salt content in water by using a calculation of mathematical algorithm that relates the measured refraction against its concentration for a specific liquid. This device is made of high-quality anti-corrosion material that provides reliability and reads salinity instantly and accurately due to its high-resolution display focused to relevant range of reef aquarium.
This extra prefilter traps the majority of coarse dirt particles, even before the water reaches the external filter. Its base rests securely on the bottom of the aquarium. The water is drawn in all round, over a wide surface area, through the modular filter baskets which can be filled with filter media and easily cleaned and replaced. For cleaning, you simply remove the filter baskets.

It is clean and safe for marine reef and hard water freshwater aquariums such as African cichlids. South Seas Base Rock can also be an interesting and realistic addition to a desert reptile biome.
