sera Rock Gray Mountain
Gray natural rock with fissured surface
The sera Rock Gray Mountain is a gray natural rock characterized by its partially smooth and partially rough surface with many corners and edges. It is particularly suited for hardscapes modeled after gray mountain formations. The small fissures and holes allow planting moss and such.
The sera Rock Gray Mountain is available in the three sizes S/M, L and XXL. The XXL version is also called a main stone and serves as a real eye-catcher in the aquarium.
- sera Rock Gray Mountain S/M: 0.6 – 1.4 kg (1.3 – 3.1 lb.)
- sera Rock Gray Mountain L: 2 – 3 kg (4.4 – 6.6. lb.)
- sera Rock Gray Mountain XXL: approx. 6 kg (13.2 lb.)
The rock is slightly lime containing so it can harden the water a bit. This means the carbonate hardness (KH for short) becomes higher. It is therefore advisable to check the carbonate hardness once a week and regulate it by partial water changes if required.
The product can differ from the picture since it is a natural product.
