Product Information
A powerful buffer substrate, the CaribSea Florida Crushed Coral is 25 times more effective than other crushed corals, dolomite or oyster shell substrates. In stunning white, it adds an almost shining touch to the base of your aquarium.
It has a huge surface area, which provides perfect biological filtration for clearer, healthier water. Each grain is around 2-5mm, boosting the bio-load up to 50%. It provides the perfect base layer of undergravel filtration.
Key Features:
- Florida Crushed Coral can be used aquariums
- Calcium reactors and plenum systems to boost carbonate and calcium levels and trace element levels too.
- Free from unwanted pollutants such as ash, metals and pesticides the CaribSea Florida Crushed Coral will not impart any nasties into your aquarium.
As it is a natural product, Crushed Coral is irregular in shape and size.

It's not the sort of substrate I usually go for but it was for a tank that was only going to have two clown fish in and due to it being a smaller tank compared to my main tank I wanted all the help I could get with the added biological filtration this should provide. -

Again a great product, only requires a quick rinse then straight in the tank. Only a small cloud in the water which soon settles.
