For determining the specific gravity with a hydrometer in saltwater aquaria
Measuring and reading the specific gravity on the scale of the hydrometer will be easy with the new Tropic Marin® MEASURING CYLINDER. The high-quality plastic measuring cylinder is transparent, has a stable base and a spout. With a height of 36 cm (14 inches), it is ideally suited to determine the specific gravity using the Tropic Marin® HIGH PRECISION HYDROMETER. It is no longer necessary to switch off the flow pump for a measurement in the aquarium; just take the monitoring of the specific gravity outside of the tank. It is really simple!
The Tropic Marin® MEASURING CYLINDER is available as single item and as set together with the Tropic Marin® HIGH PRECISION HYDROMETER.
• | Tool for determining the specific gravity in saltwater aquaria |
• | Height: 36 cm / 14 inches |
• | Content: 500 ml / 17 fl. oz. |
• | Transparent plastic (PP – polypropylene) |
• | Stable basis |
• | With spout |
• | Molded graduations |
NOTE: The specific gravity is temperature dependent. With increasing temperature the specific gravity decreases. Therefore, the measured water temperature should be 25 °C / 77 °F to obtain a correct result.
• | Fill the measuring cylinder with maximum 400 ml saltwater (water temperature = 25 ° C/77 °F). |
• | The hydrometer should be dry and clean. |
• | Gently place the hydrometer into the water until it floats freely. |
• | Now read the specific gravity on the blue part of the scale of the hydrometer at the level of the water surface – NOT at the level of the meniscus, which is creeping higher at the edges! |
• | To avoid any distortion of future measurements, rinse the measuring cylinder well with fresh tap or reverse osmosis water to remove salt residues after each use. |
DO NOT CONFUSE: The Tropic Marin® HIGH-PRECISION ARÄOMETER, which is used in German speaking countries, has a scale with a green printing and the indication Dichte/density (see Difference between density and relative density).
We recommend different salinities for various tank types:
Tank type | Specific gravity at 25 °C / 77 °F |
Salinity in ‰ (psu) |
Fish only tanks (no invertebrates) | 1.023 – 1.025 | ca. 31 – 33 |
Reef tanks | 1.025 – 1.026 | ca. 33 – 35 |
Shrimps | 1.026 – 1.027 | ca. 35 – 36 |
