FAQs

Does Seachem Flourite Dark change the pH of my water?

No, it is chemically inert and will not buffer or alter your aquarium pH.

Do I need to replace this gravel after a year?

No, Flourite is a permanent substrate and does not need to be replaced.

Can I mix this with other gravel types?

Yes, you can mix it with other substrates, though it is fully functional on its own.

Is this safe for bottom-dwelling fish?

Yes, the substrate is safe, though it is recommended to ensure your fish species prefer this texture.

How much does one 7kg bag cover?

One 7kg bag provides approximately 5,500cm3 of volume.

Troubleshooting

The water became very cloudy after filling the tank.

This is likely residual dust. Let the filter run; it will clear the water within 12 to 24 hours. In the future, rinse the substrate more thoroughly.

Plants are floating to the surface.

Ensure the plants are buried deep enough into the gravel. Use planting tweezers for precision or add a small rock to weigh down the stems until roots establish.

Pros and Cons

Pros

  • Permanent substrate that never needs replacement
  • pH neutral and chemically inert
  • Excellent for healthy root system development
  • Stunning dark aesthetic for high-contrast aquascaping
  • Porous structure aids in biological filtration

Cons

  • Requires significant rinsing before use to remove dust
  • Heavier than some alternative substrates
  • Can cause cloudiness if water is added too quickly during setup

Setup, Compatibility & Care

  1. Rinsing: Pour the contents of the bag into a bucket and rinse thoroughly with a hose or under a tap until the water runs relatively clear to minimize dust.
  2. Placement: Add the gravel to your dry aquarium, sloping it higher in the back to create depth.
  3. Filling: Place a plate or plastic bag over the substrate and pour water slowly onto it. This disperses the energy of the water flow, preventing the gravel from being disturbed and keeping your water clear.
  4. Compatibility: Safe for all freshwater community tanks, including shrimp and sensitive fish species. It is compatible with all freshwater filters and does not require special equipment.
