  • Regular price $ 3.99


Crushed coral is great for fish tanks that need a more alkaline pH. Crushed coral is known for dramatically increasing the buffering capacity of an aquarium, as well as adding to the alkalinity of the tank, raising the tanks pH. The craggy areas in the coral are an ideal place for beneficial bacteria to flourish.

Nice clean crushed coral.

Much nicer than the crushed oyster shell I was using from Tractor Supply. Slower dissolve rate, keeping a stable KH.

Does what it says

This product raises alkalinity and ph slowly, while buffering water. Watch Corey's youtube videos for instructions on using.

Great easy way to up your PH

We've been struggling with keeping our PH at 7 ever since there was a huge flood in our area. It changed our tap water chemistry. Crushed coral is the answer! Finally I have a steady ph. Like we did before the big flood.

Crushed Coral

It is just what I needed to increase kH in my aquarium and it did the trick! And it is nice that they dont force you to buy an incredibly huge amount of it at a time. Thank you!
