Tropic Marin Measuring Cylinder – 500 ml, tall cylinder for precise reef testing

Accurate, easy, and durable. The Tropic Marin Measuring Cylinder is a tall, crystal-clear 500 ml cylinder designed for reliable salinity checks and solution prep in marine aquariums. Made from PP (polypropylene) with a stable base, pour spout, and molded graduations, it pairs perfectly with the Tropic Marin High-Precision Hydrometer for consistent, repeatable readings.

Why aquarists like it

• Tall form factor 36cm keeps the hydrometer fully submerged and easy to read.

• Shatter-safe PP stands up to everyday reef use and cleaning.

• Spout + raised scale make pouring and dosing neat and precise.

How to use (with Tropic Marin Hydrometer)

1. Fill the cylinder with up to ~400 ml of tank water at 25 °C / 77 °F.

2. Gently place the hydrometer so it floats freely; read specific gravity at the water surface.

3. Aim for 1.025–1.027 SG at 25 °C for typical reef systems.
