Coralreef,

Can try sealife balestier, they still have alot left the last time i went there. They are still selling them below $10 but i think you will need to cycle them for quite long cos the ammonia smell on the rocks is quite strong.

Hi....

Will any rock do?....Today passed by Soon Heng...the 1 at Bukit Merah View.....they have the 1 in crates and smaller rocks in a box......it's says...for freshwater and marine tanks.......

Hope you guys can help...thanks......

Chris · February 19, 2003

There's no such thing as LR for freshwater or marine!!! I think its dead rock.

coralreef · February 19, 2003

Aiyah..dunno mah...so I ask lor......

the shopkeeper said...the rock was taken from freshwater area....not from the ocean.....so blur blur....dunno if should buy.....

Chris · February 19, 2003

I suggest you don't get them because the bacteria from saltwater will perish when come into contact with freshwater. That's the reason why I think LR cannot be for both water.

H****Q*** cavan road selling some.. Not so purple LR.. $10/kg.. If anyone interested..

coralreef · February 19, 2003

dodo · February 20, 2003

nleong · February 20, 2003

may i ask, how to differentiate an algae rock from a actual lichen rock (with coraline algae) ? How much purple must we look at before buying ?

Got any pictures to show or not huh? dun want to spend a fortune later find out actual buying a rock with algae. :thanks:

This is the page 1 of 6 taken from About Live Rock in Saltwater Aquariums

What Is Live Rock?

When talking about live rock (LR), it is a misconception that the rock itself is alive. What makes it live are the many forms of micro and macroscopic marine life that live on and inside of it. The rock itself is only made up of the calcium carbonate skeletons of long dead corals, or other calcareous organisms.

There are different types of live rock. In J. Charles Delbeek's article "Your First Reef Aquarium", published in Aquarium USA in 1994, under the Live Rock section he refers to "reef rock" basically as pieces of coral or coral rock from outside the reef that have broken off and fallen to the bottom that then becomes covered with encrusting organisms, such as coraline algae and sponges. "Inshore rock" Delbeek refers to as rock from inside the reef that has a tendency to be more dense and becomes covered with macroalgae, clams, mussels, crabs, shrimps, and other unwanted organisms. In Delbeek's view, reef rock is much more desirable then inshore rock because it cycles more quickly and stabilizes a tank much faster. There is also dead base rock, meaning it has no live growth on it. This is rock that is devoid of external life that probably won't see much light, so you can put other forms of more advanced live rock and corals on top of it to build your reef system base, once your tank has settled and the base rock is seeded or cured. Beginning a reef tank using seeded base live rock as the center stones of the aquarium is not a bad idea. Once the base rock is established, then you can begin to add, slowly, more advanced types of live rock.

Some descriptions of live rock sold by suppliers can be confusing. For example, Flying Fish Express describes their Pacific live rock as, "Actually pieces of coral skeletons that have broken off reefs during storms. This 'rubble' washes in toward shore where it is collected in shallow water." So, is this a lighter type of "reef" rock, or heavier type of "inshore" rock? See what we mean? For now we just wanted to make our point on this matter, but in Live Rock Part 5 - Tips For Buying LR Locally or Online, this topic is covered in greater detail by means of asking a supplier questions about what type of live rock you will be receiving.

What Is The Purpose of Live Rock?

Live rock becomes the main biological nitrification base or biological filter of a saltwater aquarium, while at the same time enhances the look of the aquarium and provides shelter for the inhabitants. To better understand what purpose live rock serves in an aquarium, Delbeek explains it like this:

"The use of live rock immediately introduces into the aquarium numerous algae, bacteria and small invertebrates all of which contribute to the overall quality of the aquarium water. Live rock has just as much, if not more, surface area for bacteria than a trickle filter. Since live rock in the aquarium contains various types of bacteria, algae and corals, waste products such as ammonia, nitrate and phosphate can have a number of fates. Ammonia, nitrate and phosphate are readily assimilated by algae and photosynthetic corals growing on and in the rock. Ammonia can also be quickly converted into nitrate by the bacteria on and in the rock. This nitrate can be either absorbed by the algae and corals, or it can be denitrified by bacteria in close proximity to the nitrate producing bacteria." -- Read More From J. Charles Delbeek

No matter what type of live rock you choose to use, as you may know, a biological filter base has to cycle and settle for your aquarium to run properly, and this pertains to the curing of live rock as well.

nleong · February 21, 2003

Qoo,

But are their LR cured ? I went there last week, saw one of the tub is muddy, believe they just got the shipment and saw a hammer on the floor, dunno if they are breaking the rock to smaller pieces

souphamster · February 21, 2003

wat u mean by cured??? :thanks:

nleong · February 21, 2003

souphamster,

read the post by Spade in this thread, the link will lead you to information you want to know.

Qoo · February 21, 2003

nleong,

I dun think the LR are cured, else they wont sell it at $8 liao.

UFO · February 21, 2003

Though the LFS always said their LR is cured, don take the risk. I tried a few time & always caused hell in my tank. I cured my LR in a clean pail with air stone & DIY wet/dry filter (I kiasu ma) for 4 weeks before I put it in the main tank. Not sure this is the right way though. Anyone?

It's also a good practise to SMELL the LR when selecting. If it small bad, better put it bad.
