Aquatic Gardens Aquarium Hydrometer with Thermometer Review

Average Reviews:

(More customer reviews)I've been in the reef aquarium hobby for around 6 years now. I purchased 3 of these in case I ended up breaking one. Not as fragile as some have suggested but it's glass so be careful. Works just fine...just be sure to calibrate it with a something of a known specific gravity to ensure you are measuring apples to apples. I'd buy again for the price.

Deep Six Hydrometer Review

Average Reviews:

(More customer reviews)You will get readings that vary wildly from one reading to the other. MY LFS tested my water to be 1.025, while this hydrometer was showing 1.022 in one reading and 1.028 in another despite tapping the bubbles off the needle. You will want to buy a refractometer after you purchase this so save yourself the $10 and invest in a refractometer. Look around and you may be able to find a used one for $30 or so.
