Aquarium Advice Regular
Ever since I've been in this hobby I've always used a swing arm hydrometer of one type or the other. I've been using the "Deep Six" model for the last several months and while being here on the AA forums have read nothing but bad things about these. I've always thought, "well how bad can these things truly be". Well after a disease outbreak and needing to use hyposalinity for a quarantine tank I decided to purchase a refractometer. The difference between the two devices is staggering.
- The swing arm hydrometer is off by a whopping -.5/SG; for example the refractometer showed my main tank at 1.26SG while the hydrometer showed 1.21SG.
Let this be a warning to everyone in this hobby. Spend the $45 dollars and get a refractometer today! It's the single best tool you can buy if you are serious about the care of your tanks.
