The new offer of air stones is a group for practical use not only for aquariums but at the same time for aeration of garden lagoons and ponds. The products are made from fine grained natural sandstone. Concerning proportions there are several sizes in basic and extended design. Especially, extended air stones have a huge efficiency. Bigger air stones intended for tough and frequent handling are equipped with the incoming plastic pipe instead of a glass pipe.

To prevent the problems and misunderstanding during the orders and communication, the names of products are described as precisely as possible. There is a handling abbreviation after the name and proportions of the product, which just like the full and short code number defines the product.
