  • Raises pH 
  • Increases KH to buffer pH
  • Adds some hardness to water

If you have softer water with low pH, KH, and GH and wish you could keep aquarium fish, shrimp, and snails that need higher pH, crushed coral is a gentle and safe way to buffer your water. Crushed coral dissolves continuously over time. The lower your pH is, the faster it dissolves. As the pH rises, it slows down how fast the coral dissolves. Crushed coral adds a bit of hardness to the water, and it significantly boosts KH which buffers pH from swinging.

Useful in Filters or Substrate

One of the easiest and safest ways to prevent harmful pH swings in your water is to increase the KH in your water by adding crushed coral to your aquarium. You can either use it as the substrate or pour a small amount into a filter media bag to use in your hang-in-back, canister, or other media-filled filter.

Rinse Before Using

Because this product is made by crushing coral, there may be some small particles or coral dust in the bag. Make sure to pour the crushed coral into a fish net and thoroughly rinse it under running water (with no soap) to prevent cloudy water in your aquarium.
