Aquarium Co-Op Crushed Coral 1 lb
The Aquarium Co-Op Crushed Coral 1 lb bag is the perfect solution for aquarists looking to raise and stabilize KH and pH in freshwater aquariums. Naturally sourced, this crushed coral slowly dissolves over time to provide a steady buffer that prevents dangerous pH swings and keeps water chemistry stable. It’s ideal for livebearers, African cichlids, and shrimp tanks that thrive in harder, more alkaline water.

Why Choose Aquarium Co-Op Crushed Coral?
Aquarium Co-Op crushed coral is a trusted, hobbyist-favorite way to buffer soft or acidic water without harsh chemicals. Because it dissolves gradually, it provides consistent, long-term stability rather than the spikes you get from liquid additives — making it one of the easiest ways to keep sensitive fish and invertebrates healthy.
Care Guide
- Add directly to your filter media bag, substrate, or mix into gravel
- Rinse before use to remove dust and fine particles
- Replenish as the coral dissolves over time (every few months)
