Reef Crest Malaysian Mangrove Sinking Driftwood - 16–20 Inch Overview Larger statement pieces of dense sinking driftwood suited to medium and big tanks. Create dramatic roots and archways, break line of sight for shy fish, and establish a stable hardscape that matures beautifully with plants and patina. Features Hefty hardwood that anchors layouts without added weights Branching forms for instant caves, perches, and visual height Ideal mounting surfaces for epiphyte plants and moss walls Natural tannins promote a healthy, bioactive environment Preparation and Use Rinse well. Pre-soak several days or boil to speed sinking and reduce tannins. Expect temporary biofilm; it is normal and easily managed by cleanup crew. Use gel super glue or thread to attach plants; avoid wedging tightly against glass. Water Chemistry and Compatibility May slightly lower pH and soften water; amber tint is common early on. Excellent for blackwater and community setups. Use chemical filtration if you prefer less tint. Specifications Selection size: approximately 16–20 inches (varies naturally) Sold individually; shapes, thickness, and mass vary Freshwater safe; sinks after saturation

Reef Crest Malaysian Mangrove Sinking Driftwood - 12–16 Inch Overview Dense branch and root pieces ideal for natural freshwater aquascapes. This sinking driftwood adds instant structure for hardscape layouts, provides fish and shrimp shelter, and releases beneficial tannins for a subtle blackwater look. Features Naturally sinking hardwood with rugged textures and branching character Excellent anchor surfaces for Anubias, Java Fern, Buce, and moss Encourages biofilm and microfauna that invertebrates graze on Each piece is unique in grain, shape, and tone for one-of-a-kind scapes Preparation and Use Rinse thoroughly, then pre-soak for a few days or boil to accelerate saturation and reduce initial tannin release. Expect a harmless white biofilm in the first weeks; shrimp and plecos consume it. Attach plants with gel cyanoacrylate or thread. Place wood first, then add substrate to lock in position. Water Chemistry and Compatibility Tannins may tint water amber and can gently soften water and lower pH. Great for tetras, rasboras, gouramis, bettas, and shrimp. If you prefer crystal-clear water, use carbon or frequent water changes. Specifications Selection size: approximately 12–16 inches (varies naturally) Sold individually; shapes and mass differ piece to piece Freshwater safe; sinks readily once saturated
