Slate for aquarium - Price per kilo

A few tips before using natural rocks:

• Please rinse the rocks and stones with water before use. Some rocks contain dust and deposits. Please use a brush to clean it before introducing the stones into the aquarium.

• You can easily test if a rock is inert or if it will change pH and hardness slightly. Simply place a few drops of vinegar on the rock. If the vinegar (a basic substance) fizzes or foams, it indicates that the rock contains calcium.

• Stones containing calcium will alter pH and kH , which can be especially pronounced if you have acidic water or CO2. You can easily control it by regular water changes with osmotic or soft water. You can also use a permanent water softener.

• Rocks can be very heavy and sharp. Therefore avoid placing them directly on the glass , just place the substrate before placing the hardscape. The substrate will also help you fix the exact position of the stone with more freedom.

• Always secure stones , especially when placing one stone on top of another. During regular maintenance, the top rock can shift or fall by accident, injuring your inhabitants or even damaging the aquarium.

• Remember to always place the stones a few centimeters from the walls of the aquarium to facilitate maintenance.
