Olive Knott - Shrimp Scoria Black 2L

Premium black volcanic scoria developed for shrimp and planted aquariums. Its ultra‑porous structure supercharges beneficial bacteria, supports stable, slightly acidic to neutral parameters, and offers excellent root grip for healthy plant growth. The deep black colour enhances shrimp and plant contrast for a striking aquascape.

Key features

• Natural volcanic scoria: High surface area for strong biological filtration and clearer water.
• Shrimp‑safe and inert: Designed to help maintain stable, shrimp‑friendly conditions.
• Plant‑friendly texture: Irregular grains anchor roots and promote circulation around root zones.
• Bold aesthetic: Deep black substrate makes shrimp colours pop and hardscape lines stand out.
• Easy layout: Rinses quickly, levels well, and allows clean slopes and contours.

Coverage guide

• 2 L covers roughly 20–25 cm x 20–25 cm at ~5 cm depth, depending on grain geometry and compaction.
• For planted layouts, aim for 4–6 cm depth; add volume to build front‑to‑back slopes and hardscape elevation.

Setup tips

• Rinse lightly to remove transit dust, then spread and shape slopes before filling.
• Place a plate or plastic sheet when filling to prevent clouding; run fine mechanical media to polish water.
• For heavy root feeders, combine with root tabs or a nutrient soil base beneath the scoria.

Care and maintenance

• Spot‑vac debris on the surface without over‑disturbing roots or substrate structure.
• Gently aerate low‑flow zones periodically to prevent compaction in dense plantings.
• Match GH/KH to shrimp species using remineralisers where needed.

Ideal use cases

• Neo/Caridina shrimp displays requiring stable, bio‑rich substrate.
• Planted nanos and mid‑size aquascapes prioritising contrast and clean lines.
• Scapes seeking added biological capacity within the substrate itself.
