Frequently Asked Questions (FAQs)

1. Is coral stone good for aquarium?

Coral stones not only can be a decoration for the aquarium tank but also play a part in maintaining PH value. The coral-stone is also known as filter media which cultivate nitrobacteria for balancing the aquarium ecosystem. Both marine and freshwater are suitable for having coral stone as filter media.

2. What stones are safe for aquariums?

Safer rocks include:. Granite.Quartz.Slate.Lava rock (take sharp edges into account, particularly with fish that have sensitive barbels, such as the Cory species)Onyx and ground glass.Sandstone (always test before using, as it may contain traces of limestone)

3. Will coral grow on dry rock?

Will coralline algae grow on dry rock? Absolutely, as long as you add an initial source like a bit that comes in on the bottom of a coral or on a single piece of live rock from an established tank that you trust. You can speed the process up a bit by scraping it off a rock allowing it to spread around quicker.

4. Can I put coral rock in a freshwater tank?

Absolutely not! Live corals make stunning additions to marine tanks, cannot survive in freshwater and will gradually die off when placed in this environment. To make things worse, the corals will pollute your aquarium as they die, releasing ammonia and nitrates that can be harmful to your fish.
