Review on Accurate Water Testing Made 🌊 Easy with AQUARIA MARINELND EDWARDSVILLE 02503 Hydrometer by Bernardino Suazo

So far this block has worked perfectly. When comparing it with my friend's more expensive tester, I get exactly the same readings as his. Follow directions and rinse with fresh water after each use for accurate readings. Salt water has caused the lettering or the e where the reading is showing to come off a little, it's not a big deal and not all at once as I would expect with multiple uses in salt water. I scrawled the line where I want my saltiness, which makes it easier for my wife to read anyway.
