![]() Her only disadvantage, for apersonal opinion, is the aesthetic effect a little bit “synthetic” for its shine and color. QUARTZ ROCK: Quartz is a very present mineral on the earth’s crust and is composed of tetrahedrons of silicon and oxygen, it is presented in various shapes such as sandstone and granite, usually in aquarium we find it in the form of small pebbles or gravel to form the substrate and It has the characteristic of not releasing carbonates, so it will not change the water values. ![]() Slate has the characteristic of not releasing carbonates and therefore will not alter the water values, so it can be used in large quantity in the composition of the layout. The color is very dark, usually black or dark green, with some white veins. SLATE STONE: This rock originates from thin silt stratification, has a relatively light weight and is mainly composed of slabs, which offer large smooth surfaces (very useful for laying eggs of some species) and has a very elegant and useful shape. Another excellent quality is also to not alter the water values. ![]() For this reason it is also used in reduced forms as a substrate to facilitate the water flow and to make the bottom more oxygenated. This is a good feature for the total weight on the glass of the tank, but the most important feature of these rocks is the presence of millions of micro-holes that will help the establishment of nitrifying bacteria, such as Nitrobacter and Nitrosomonas, propedeutic to aquarium development. LAVA ROCK, POROUS STONE: These stones are natural aggregates of lava of volcanic origin and therefore very light because they are exceptionally very porous. Finally, it is advisable to make a good washing and boiling, because in the holes there is a lot of mud or soil and can caused consequence like the possibility of contamination of the biosystem. ![]() Dragon stone is very good for epiphytic plants that will attack very quickly and has the good characteristic of not releasing carbonates, therefore will not alter the water values, so it can be used in large quantity in the composition of the layout. They are very famous for their rich coves and crevices, they recall rocky landscapes and are great for epiphytic plants and Iwagumi aquariums being of limestone origins, unfortunately release carbonates and therefore alter the values of water, so it will have to be used in little quantity in the composition of the layout or we suggest, besides the above described treatment, to place these in 30% HCl hydrochloric acid solution with water and leave for 3/4 days to react the outer part of the rock and release less carbonate when will be used in the tank.ĭRAGON STONE: Like Seiryu Stone and Mountain Stone are the most used in Takashi Amano’s layouts, the color are brown and dark yellow with red or green reflections, has the characteristic of being very light for their numerous holes and creeks, so it is practical for the glass basins of the tanks. SEIRYU STONE , MOUNTAIN STONE: There are rocks of limestone origin, along with Dragon Stone and Mountain Stone are the most used in Takashi Amano’s layouts, the color is from dark gray to light gray with white veins. More the reaction will be stronger, more the stone is alkaline and will release carbonated in water that will increase PH, GH, or KH.ģ – Wash thoroughly with the help of brushes under water to remove debris or any animal inside.Ĥ – Boil in water for 30 minutes to eliminate all possible pathogenic elements such as bacteria or tiny insects. In this article we will know all the most famous and common stones that we find on the market like Seyryu stone, Dragon stone, Mountain stone, lava rocks, quartz, pagoda, rainbow stone, slate, bricks, sodalites and river pebbles But before explane all details it is very important to know the treatment that you will must to do in all cases before being placed in the tank.ġ – Know for certainty the alkalinity of the rock and the release of elements that could affect the water’s water values such as PH, GH, KH, Nitrite and Nitrate.Ģ – Carbonate self-test by putting a simple drop of limescale “Viakal” or Muriatic Acid or HCL Chloride Hydrochloride and wait for the “sizzling” reaction. Usually when we want to set up an aquarium, especially if we want a “Iwagumi” style layout, that is composed mainly of stones and vegetation, we need a lot of rock material, for this reason we need to know the aesthetic and chemical effect of each rock that we place in the biosystem. In aquariums, the rocks are very used as a decorative element of a tank, and with the advancement of Aquascaping the demand for the most varied forms and qualities has increased.
