This refractometer provides accurate readings for my reef tank. I no longer have to guess salinity levels—everything is clear and precise. The display is easy to read even in low light. Great tool for maintaining stable conditions in my coral tank.

I’ve used this for several months now and it’s reliable. It shows salinity clearly and matches what I see in my tank’s water. Not as sensitive as some lab tools, but perfect for home aquariums.
