The hydrometer is broken. It contains a red liquid. What does the red liquid consist of and is it toxic?
The hydrometer doesn’t contain any mercury. The liquid contains an alcohol solution with colouring. It is non-toxic. Both ingredients are quickly broken down by the bacteria in the aquarium. Furthermore the diluting effect should be taken into consideration. The silvery pearls are an iron compound and are therefore harmless. Simply siphon them out of the aquarium.

What range does the scale of the hydrometer cover?
A reading accuracy of 0.0005 units makes the hydrometer very accurate. _x000D_ The built-in thermometer, which covers a scale from 9°C to 32°C, and the temperature correction scale gives you the highest precision. The density is determined in a range of 1016 to 1028.
