Recommendations: 

- Most of our gravels come completely clean. Even though, we recommend to rinse gravels with water before use to remove any remaining dust and to avoid buoyancy of particles on the water fill up.
- Gravels that contain calcium may 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 water softener.
- We highly recommend you to mix different sizes to create depth in your aquarium. By doing so, it will also look more natural.
