Water Chemistry Impact: Raises pH and hardness (KH & GH)
Compatibility: Great for neutral to hardwater tanks; safe for Neo shrimp, snails, and small fish
Restrictions: Caution with Caridina and soft-water species; avoid over-stacking
Aquascape Style: Smooth flow and contrast; ideal for minimalist layouts
Placement: Centerpiece stones, balanced clusters, or contrast features
Special Features: Pale coloration, smooth surfaces, inert and shrimp safe
Water: May slightly raise hardness and pH; best in neutral to hardwater setups
Tank Size: Works in both small tanks and large aquascapes
Substrate Pairing: Contrasts beautifully with dark soils or fine sands
Design Tip: Use as bright focal stones against darker backgrounds
Appearance: Smooth, pale metamorphic rock
Color: White to light gray
Texture: Smooth with subtle fractures
Impact: Creates clean, minimalistic contrast in layouts
