Grade A
The rock is clean (limestone constitutes 100% of the weight), prepared for an aquarium. We take care of consistent quality, which is visible in every single piece of limestone. The majority of stones of this type are very hollow and have a nice bright shade.
Grade B
A very nice porous rock with holes and slight discolourations which also give it additional charm.
Grade C
The third type of rock is characterised by the fewest number of holes; colour ranges: mainly from creamy to yellow. The stones may be slightly dirty.
NATURAL OCEAN ROCK
It may constitute a basic building block for aquariums with stone and rocky decor, creating beautiful backgrounds, hiding spots, substrates. Limestone is usually used to decorate Tanganyika and Malawi biotope aquariums with cichlids. You can create beautiful rock compositions that often resemble a reef and a marine aquarium, hence limestone is so popular. It is also used as a base for living rock in marine aquariums.

On average, 1 kg of limestone occupies more than 1l by volume; 10 kg of limestone is +-12-20 l; 20 kg – +-25-40 l; 30 kg – +-40-70 l.
For larger aquariums, we recommend to purchase rocks of different types since those of inferior quality can be used as a base for an aquarium design. Choosing our offer, you will receive a perfectly composed set of stones of different sizes. You can rely on our many years of experience. We select carefully selected pieces only.
Proposed amount of stones depending on the length of a tank:
1 kg = 2-3 pieces 5-10cm
1,8 - 5 kg = 30cm / 1ft in length
8 - 10 kg = 60cm / 2ft in length
10 - 15 kg = 80cm / 2,5ft in length
15 - 20 kg = 90cm / 3ft in length
20 - 25 kg = 120cm / 4ft in length
40 - 50 kg = 150cm / 5ft in length
60 - 90 kg = 180cm / 6ft in length
