Gray Coast

Initial Setup:

1. Rinse the Substrate:

   • Thoroughly rinse Seachem Gray Coast to remove any residual dust. This helps to minimize initial cloudiness in the aquarium.

2. Add the Substrate:

   • Spread the rinsed Gray Coast evenly across the bottom of the aquarium to create a substrate bed.

3. Fill the Aquarium with Water:

   • When adding water to the aquarium, pour it slowly to avoid disturbing the substrate bed. A helpful tip is to place a bowl in the aquarium and pour water into the bowl, allowing it to overflow gently onto the substrate.

4. Clear Initial Cloudiness:

   • Initial cloudiness is normal. To accelerate clearing, use mechanical filtration (such as filter floss) and consider adding Seachem Clarity to the water.

Maintenance:

1. Regular Monitoring:

   • Regularly check and maintain optimal water parameters, including calcium, alkalinity, and pH levels, to ensure a stable environment for your aquatic life.

2. Water Changes:

   • Perform regular water changes to maintain water quality. This helps to remove any accumulated waste and replenish essential minerals.

3. Substrate Cleaning:

   • Periodically clean the substrate using a gravel vacuum during water changes. This helps to remove detritus and prevent the buildup of harmful substances.

4. Supplementation:

   • Consider using additional supplements like Seachem Stability to enhance the biological filtration and overall health of your aquarium.
