Coral Rubble 1kg
Natural Calcium Source for Aquariums & RO Remineralization
Coral Rubble is a natural and effective way to increase carbonate hardness (kH), general hardness (gH), and stabilize pH levels in freshwater, marine, and reef aquariums. Made from crushed coral fragments, this mineral-rich media slowly releases calcium, magnesium, and trace elements—perfect for RO remineralization, hard water aquariums, or as a plant nutrient additive.
Ideal for use in filters, sumps, or as substrate support to maintain water chemistry balance naturally.
Key Features
-
Raises kH and gH naturally to stabilize aquarium pH
-
Ideal for RO/DI water remineralization
-
Provides calcium and trace minerals beneficial to aquatic plants and invertebrates
-
Suitable for freshwater, marine, and reef systems
-
Can be used in filter bags, media reactors, or directly in the substrate
Usage Suggestions
-
For RO remineralization: Add small amounts to the filter chamber or a media bag.
-
For aquascaping or substrate use: Layer beneath gravel or use as decorative media.
-
Rinse before use to remove fine dust.
