Raise pH Naturally
- 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.

Customer Reviews
Definitely take the time to rinse it. I was having kh issues. Crushed coral saved the day. I put mine directly in the gravel. The pieces are small enough that it blends in nicely. If I need more calcium, I’ll add it to my box filter. I definitely recommend this (and all) and all products by ACO. 💚
Great product. I was having trouble maintaining a good Gh level with the water I have. Stable now
Not much else to say, thank you Aquarium Co-op!
Shopping online was easy and quick! The support team has always responded to my emailed questions within an hour!
Seem to do the job. My water was uncomfortably soft and adding these into my 29g substantially raised both the GH and KH within days while leaving my pH in the high 7s as desired.
Just make sure to wash very thoroughly, more than instructed on the packaging. Unless you’re okay with a lot of little milky dust in your tank for a while.
