    Perfect for salt water tanks
    Came perfect salinity level in very first time. very surprised. then I played little with this meter to make sureit is correct salt and water ratio for my marine aquarium, I added little more salt in the same water and then checked again and meter showing high level of salinity in the water, then I did add back some fresh water and checked the salinity. I got a perfect reading which is ideal for a salt water tank.It worked for me and very good price.

    Comparison With Spectrophotometer
    After purchasing this product I ended up purchasing a spectrophotometer. I just felt more comfortable With the results and it’s a lot less hassle to keep doing repeat tests to tweak the salinity of water. Having said that, this isn’t a bad product, it’s a lot less expensive than the spectro and it will get the job done. It reads surprisingly close to the spectrophotometer.

    Great for a pico saltwater tank salinity checks
    Purchased for a pico saltwater tank. Works great with a turkey baster and doesnt spill. Easy to pour back in.

    not very accurate.
    The one I got reads very low…this one read at 1.022, my SeaTest brand floating needle read 1.026 and my refractometer read 1.028.The refractometer seems to be the most accurate as I get 0.0 with distilled water and 1.026 with 1.026 calibration fluid.I can still use this hydrometer if I just remember or mark how far it is off and compensate accordingly, as I like these dip/floating needle meters for a quick check while mixing synthetic sea salt. I then fine tune it with a refractometer.I wouldn’t rely on this alone.

    Works great
    It took a few tries to realize that you have to use the and to remove bubbles, but after that, simple and easy to read.

    Scale too large to use with Goldfish pond.
    The scale is too large to be of use with a fresh water pond in which salt is added as an aid to gold fish. Since the ideal amount is less than one half of the distance between the first and second increment. However I can imagine this would be good for saltwater tanks.

    Would be nice if numbers were larger
    It works but for brackish water it is difficult to read because it starts so low on the scale – my figure 8 puffer needs around 0.4 and it’s so hard to gauge because it’s made for a higher salinity
