## Questions & Answers

**Q: For anyone that has bought this product, does it truly turn into a live coral reef overtime? If so what period of time?**
A: I used this rock in my salt aquarium. It's a great rock but I found I needed to break it up and used marine safe glue to build my tank. Salt water tanks are like creating the ocean. This rock does not turn into a live coral reef. This rock is dead and needs to he cured. To cure rock you must put in salt water for several weeks usually in a dark environment with lots of circulation. After its cured you put into a new aquarium with zero fish or coral and you then cycle the aquarium for another 6 weeks.  The cycle is when you introduce bacteria most common with a piece of raw shrimp.  The shrimp breaks down and creates ammonia and bacteria then consume the ammonia and the cycle process begins. You can buy cycle in a bottle but you should still wait a few weeks before you can add fish. 
You need to test the water and note when the ammonia levels spike and fall naturally.  When you read about live rock, it is rock that has marine organisms living within but this is not coral.  Think of coral like trees in a forest. They spread by seeds but need a tree to begin with.   You can buy live rock from a fish store or online but you will pay a lot more.  If you do buy live rock you may find a coal growing in a year or so but that's not a guarantee.   Almost all corals you see in tanks are from other coral that were cut off called frags and then glued to other small rocks.  Some corals spread faster than others and there are different categories.  I suggest you spend a few weeks watching videos and really understanding salt water tanks before you enter the hobby. You will save yourself thousands of dollars by being educated.

**Q: Can this rock be immediately cycled or do I need to cure it first?**
A: It is not live rock, so it can be cycled right away.  I suggest soaking it in a bucket a couple of days first though as it has a lot of soft spots.

**Q: Can you use this in a african cichlid tank?**
A: Yes

**Q: Does it need to be soaked**
A: No just rinse it off
