The settling tank is a large vessel, usually made of food-grade stainless steel, in which freshly extracted and strained honey can rest for a few days before bottling. During this resting period, the finest wax particles, air bubbles and other small impurities that even fine sieves cannot hold back rise to the surface on their own, because they are lighter than honey.
After a few days of resting at room temperature, a thin layer of foam and wax particles forms on top. This layer is removed with a dough scraper or a ladle, the so-called skimming. Only after that is the honey considered fully clarified and can be filled into containers or directly into jars. Many settling tanks have a pinch valve or gate valve at the bottom, through which the clarified honey can be drawn off in a controlled way at the bottom, while fresh honey is topped up at the top as needed.
In practice, the size of the tank matters: it should suit one's own harvest volume, so that the honey does not sit too shallow or too deep in the vessel and can clarify evenly. A common mistake is too short a resting time or too cold a storage room, which means air bubbles and wax residues do not rise fully and later become visible as an unsightly layer in the jar.
