Gentle, Long-Lasting KH & pH Support for Axolotl Aquariums

Give your axolotl aquarium a little extra protection against changing water chemistry with our convenient 3” × 8” mesh bag of crushed coral.

Crushed coral is naturally rich in calcium carbonate, which slowly dissolves in aquarium water and helps increase carbonate hardness (KH). By providing additional buffering capacity, it can help your aquarium resist sudden drops in pH and maintain a more stable environment between water changes.
