Ensuring spotless lava rock not only keeps your aquarium dwellers safe but also maintains the integrity of the water conditions.

Step By Step Cleaning Procedure

Keeping your aquarium ecosystem healthy starts with clean decor. Lava rock, with its textured surface and porous nature, is perfect for beneficial bacteria. Yet, it can harbor unwanted grime. A thorough cleaning maximizes its benefits. Follow this simple Step by Step Cleaning Procedure to ensure your lava rocks are pristine and safe for your aquatic friends.

Initial Rinsing To Remove Loose Debris

Start by placing your lava rocks under running water. A gentle stream works best. This will dislodge loose particles. Use your hands to rub the rocks. Doing so removes any easily accessible dirt.

Soaking Lava Rock To Loosen Impurities

Fill a bucket with a mix of water and aquarium-safe cleaner. Let your lava rocks soak for about an hour. This helps in breaking down tougher impurities.

Scrubbing To Remove Algae And Bacteria

After soaking, scrub each piece with a soft-bristled brush. Focus on grooves and holes. This helps eliminate algae and bacteria that might be clinging to the rocks.

Boiling Lava Rock For Deep Cleaning

Boil water in a large pot. Place your rocks inside for about 15 to 20 minutes. Boiling kills off any persistent organisms. Ensure your rocks are fully submerged to avoid potential thermal shock from uneven heating.

Final Rinse And Inspection Before Placement

Give the rocks one last rinse with tap water. This removes any residues from the cleaning agents. Inspect each rock closely. Look for remaining debris or organisms. Only place the rocks back into the aquarium once they are completely clean and cool.
