About This

• Light weight, can float in water.
• Anti acid, anti radiation, corrossive resistant, and does not pollute the water.
• We will prepare a little hole in the rock. You can tie the suction cup and the rock with the moss thread and fix the suction cup in the bottom of the tank to build the floating rock landscape
• The floating rock is a porous lightweight glassy acidic volcanic eruption rock, its composition corresponds to rhyolite, more than 50% of its pore volume station rock volume, surface roughness, grain capacity of 250kg / m3 (water is 1000kg / m3), so do not sink in the water.
• Color: Grey ,Shape:Irregular
