Need to Know Advice on Live Rock
The term live rock can be rather confusing to many beginners. Live rock is not actually a living rock. The rock is given such a name because of the life it carries. It carries useful algae, bacteria, sponges, invertebrates, nutrients, and salts which can be useful if introduced into an aquarium. Live rock is a rock taken from the ocean. It is composed of calcium carbonate remains of long dead corals and introduced to a salt water aquarium to bring in some benefits. This is helpful since the purpose of a successful aquarium is to simulate the natural environment as much as possible.
Before you start a live rock aquarium, let me inform you that environmentalists would be grateful if you choose a different category for your aquarium. “Why?” you ask? The reason is that many people have been harvesting live rock from the marine bodies and the rock now faces extinction. The more consumers continue to buy the live rock from local shops, the more the shops are inclined to go and harvest it from the seas. As a result, there is an increased probability that the rock will become extinct.
Well, if you have already have bought your live rock or still want to continue regardless of its impending extinction, here is some advice on keeping live rock. Live rock costs around 7 pounds per pound if cured. The uncured must cost less than this. It is advisable that you start on uncured live rock from your tank rather than the cured. Doing this enables and gives ample amount of time for the life in your live rock to develop and also helps in cycling your tank. So when you visit your aquarium shop, ask for uncured live rock and make sure it is uncured live rock that they provide.
There are, however, drawbacks of using uncured or second hand live rock. If you get live rock from someone’s tank and do not cure it, it can carry with it infections from the previous tank. These infections will be introduced into your own tank. Uncured live rock can carry with it algae and anemones which can affect your tank and possibly disturb its marine life. You can choose to allow live rock to die off and then bring it into the tank. However, bear in mind that such rock may be full of nitrites or phosphates which it may introduce into your tank.
