Casual Monitoring
If you're looking for a quick and reasonably accurate salinity reading without the hassle of a more precise device, this hydrometer does the job well. It's great
If you're looking for a quick and reasonably accurate salinity reading without the hassle of a more precise device, this hydrometer does the job well. It's great for ballpark measurements and daily checks. One crucial tip: you must season the needle by soaking it in 35ppt salinity water before use. I noticed a 1ppt discrepancy before seasoning, which could explain why some users report inaccurate readings. The scale markings are clear and easy to read, and I appreciate the thoughtful addition of a bubble remover on the intake—it helps ensure more reliable results. Overall, a solid tool for casual aquarium monitoring.
Works well and cheaper
Works well,cheaper option for those just starting out. Worked better in bright light or holding up to light. Clear color and no tint like other kinds.

Fun gadget but not always the most accurate
Loved the simplicity but wasn’t always the most accurate l. I have a refractometer and that is the most precise and felt that I had to compare the two devices.
