Decorative stones for your aquarium and aquascape
In aquascaping, stones are a vital part of the hardscape, in other words: the decoration inside the aquarium. There are e.g. very puristic layouts, called Iwagumi, which are based on Japanese design principles and - apart from aquatic plants - use only one single type of stone and are designed without driftwood. In our online shop we offer many different types of stones, which are suitable for use in aquariums. The price is usually per kilogram. To hel calculate the right amount of stones, we have penned the article Choosing your hardscape by weight for our Aquascaping Wiki. The calculation takes into account all individual parameters in terms of weight and volume of each individual type of stone.
Basically, you should differentiate between neutral and water-hardening stones to be used in the aquarium. Sorts like Lava, Dragon Stone (Ohko Stone) and Loa Rocks are classified as water neutral, as are most stone types offered by manufacturer ADA. These include Manten Stones, Unzan, Koke, Sansui, Kei and Yamaya Stones. As a little note on those: ADA stones are shipped in units of 25 kg boxes, Unzan Stones are offered in our webshop as indidually photographed one-offs.
Stones that harden the aquarium water contain lime, which can sometimes be noticed as whitish veins in the stone. A hardening, in other words: an increase in total-, carbon hardness and the pH value, happens foremost, if a CO2 system is in use. When introducing the gas, small amounts of carbon dioxide are created, which constantly dissolve the lime out of the stones. In order to counteract the hardening, we recommend regular, larger water changes in the aquarium with very soft or even demineralized water or just using non-hardening rock types. This is especially recommended if you want to keep sensitive dwarf shrimp (e.g. Bee shrimp). They do not tolerate fluctuations in water hardness, which would inevitably occur in the event of a water change, very well.
Especially the heavily rugged types of stones, popularly used in aquascaping to create mountain-like structures, are often calcareous. Among those are Seiryu Ryuoh (Mini Landscape), but also Grey Rocks, Frodo, Black Pagoda and Tsingy Rocks.
A comprehensive overview of all stone sorts available in our webshop can be found in the article Hardscape in our Aquascaping Wiki. All stone types are listed and described there separately, divided into neutral and hardening types.
