About this item
- USE WAY: Insert the hydrometer at least 15 cm deep into the tank (if the insertion line is less than 15 cm, the grease on the tank will affect the accuracy of the test).
- READING SCALE: The aquarium marine sea saltwater is based on the internal reading of the scale, based on the salinity of the horizontal scale (PPT). The recommended ratio of water in a tank is between 1,020 and 1,023 (safe range). Rinse with water after each use.
- PAY ATTENTION: Bubble attachment on the pointer may cause incorrect reading. Please use the hydrometer to carefully buffer bubble attachment.
- AUTOMATIC WATER LEVEL: When the water reaches the state of full water (upper part with guide plate), lift the hydrometer, the product can be manually or hung on the cylinder, with automatic water level function, can automatically find the water level, to avoid errors.
- APPLICATION RANGE: The aquarium marine sea saltwater is suitable for warm water (20-30℃). A change in temperature will cause a change in the reading. Unit specific is accurate to ±0.001.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
