bioRocks are all-natural stones. Therefore, we recommend:

  • Please rinse rocks and stones with water before use. Some rocks as Dragon stone contain soil and loam deposits on its unique dragon scale shape. Please, use a brush to clean it before introducing the stones in the aquarium. 

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

  • Stones with calcium will alter the pH and kH.This can be especially pronounced if you have acidic water or CO2 addition. 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 to place them directly on the glass, simply place substrate before placing the hardscape. Substrate will also help you to fix the exact stone position with more freedom. 

  • Always secure the stones, specially when placing one rock on top of another. On a regular maintenance the top rock may move or fall by accident harming your dwellers or even braking the aquarium.

  • Please, always position stones few centimeters/inches away from aquarium glass walls in order to facilitate maintenance.
