Single Product

The simple, all-natural solution for stabilizing your aquarium’s water chemistry. Our premium-grade Crushed Coral is thoroughly washed, completely natural, and packed in a convenient, durable 1-pound mesh media bag. Designed to slowly dissolve over time, it provides an ongoing, self-regulating defense against dangerous pH crashes by naturally boosting your water’s mineral content.

• Ultimate pH Buffering: Tired of fluctuating water chemistry? Crushed coral slowly releases calcium and carbonate into your water, naturally raising low pH levels and stabilizing them within a healthy, alkaline range (7.4 – 8.2.)

• Boosts KH & GH: This 1-pound pack increases Carbonate Hardness (KH) and General Hardness (GH). This provides the essential mineral skeleton building blocks that African cichlids, livebearers (guppies, platies, mollies), and snails need to thrive.

• Ready-to-Use Mesh Bag: No messy measuring or loose debris. The included heavy-duty mesh media bag keeps the coral safely contained while allowing maximum water flow. It is perfectly sized to slip right into your HOB (Hang-On-Back) filter, canister filter, or sump.

• Protects Beneficial Bacteria: A sudden drop in pH can stall or completely crash your aquarium’s biological filter. By keeping your KH stable, crushed coral ensures your beneficial nitrifying bacteria stay active and healthy.

💡 Prep Tip for Aquariums: While our crushed coral is pre-washed, shipping can cause the pieces to rub together and create a harmless white dust. Give the mesh bag a quick rinse under cold, running tap water for 1-2 minutes before placing it into your filter to ensure your aquarium water stays crystal clear.
