🐠 Accurate Aquarium Hydrometer: Fluval Sea for Optimal Water Salinity Monitoring, Medium Size Review

As a longtime fish owner, I've used several hydrometers throughout the years, but none have been as precise as this one. Based on our own experience, the Fluval Sea Hydrometer has consistently given accurate readings, ensuring the health and safety of our aquatic pets. The easy-to-read display and durable design make it a reliable addition to any aquarium. The only downside is that it requires a bit of calibration before use, but it's a minor drawback for such a quality product. Overall, highly

I bought one from the store and then bought another from Revain. They are exactly the same. Both gave me no reading. Everyone stayed down. This resulted in excessive salinity in my water and killed all the coral.

As a freshwater enthusiast, I've been fascinated by seawater aquariums since my first year at school 30 years ago. Although I'm still learning, this thing works like a charm. My testimony speaks for itself. I like that it can be attached to the inside of the aquarium with a suction cup. I use it as a mixing guide etc. Yes, I highly recommend this product!
