Crushed Oyster Shell 500g
Product Details
Brand: Brooklands Pet Products
Crushed oyster shell is a natural, budget-friendly calcium carbonate source used to raise and stabilize water hardness (KH) and pH levels in both freshwater and saltwater aquariums. It acts as a slow-release buffer, dissolving when acidity increases, making it ideal for African cichlids, livebearers, or to prevent "old tank syndrome".
Key Details for Use:
- Purpose: Raises KH (Carbonate Hardness) and stabilizes pH.
- Application: Place in a mesh/nylon bag within the filter or high-flow areas (e.g., sump) to allow for easy removal once desired levels are met.
- Preparation: Thoroughly rinse to remove dust and debris.
- Dosage: Monitor closely to prevent excessive pH spikes, especially in smaller, 5-gallon tanks.
- Alternative: Often used as a cheaper alternative to crushed coral.
Oyster shells are excellent for adding calcium to the water, which can benefit shelled creatures and some fish.
