Many tank inhabitants are sensitive to even minor changes of the water conditions. These should therefore be kept as constant as possible in the optimum range for each tank.\u003c\/p\u003e\n\u003cp\u003eThe specific gravity of natural seawater of 35 ‰ (psu) is 1.026 – compared to water measured at 25 °C \/ 77 °F. Our recommendation for aquarium water at 25 °C \/ 77 °F is 1.025 - 1.027 (depending on the tank type). For an exact, reliable measure of the specific gravity, we recommend to use the Tropic Marin® HIGH-PRECISION HYDROMETER.\u003c\/p\u003e\n\u003cp\u003eMeasuring 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!\u003c\/p\u003e\n\u003cp\u003eThe Tropic Marin® MEASURING CYLINDER is available as single item and as set together with the Tropic Marin® HIGH PRECISION HYDROMETER.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTropic Marin® HIGH-PRECISION HYDROMETER:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum deviation: 0.001 at 25 °C \/ 77 °F\u003c\/li\u003e\n\u003cli\u003eScale from 1.021 à 1.031\u003c\/li\u003e\n\u003cli\u003eResolution: 0.0001\u003c\/li\u003e\n\u003cli\u003eRecommended range: 1.025 to 1.027 (at 25 °C \/ 77 °F)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Tropic Marin® MEASURING CYLINDER is made of PP (polypropylene).
