Need Advise : Coraline Alage On Lr

[Jas]

Need help,

Bought 25kgs of LR from PR at Balestier last week. Very nice rocks (they said its imported from Fiji/Tonga or somewhere far away), covered with coraline alage.

Its been in my new 3ft tank for a week now (tank is still cycling), notice that the coraline alage is "dropping off" bit by bit.

What must I do to keep the coraline alage "alive"?? Is it something to do with the light? water? calcium? temp?

I did a search but could not fine much info on coraline alage (alot on white stuff, smelly rock, etc.) Would appreciate advise from the pros.

It would be such a waste if all the corline alage drops off, than its no different from the cheap $8 rocks.

Hi, possible for experience bros to show a pic how coraline looks like on LR and why it drop off as mentioned by bro above ? I also keen to know as small pcs of white colored rock drop off too. Wonder it is coraline.

Coralline algae is the correct spelling... or your searches won't show anything.

Anyway.... coralline algae should be given good water quality or they may bleach and die off. They won't 'drop' off as they are encrusting organisms and will be part of the LR (unless you break them off).

Give them an environment with good water flow, high calcium levels, consistent KH and PH and they will grow back.

jas, check again using the correct spelling.

GARF has some good articles ;http://www.garf.org/coralline.html

Nickel- purple coralline dies when it turns white then flakes off(this happens when there is a sudden change in water quality or to a different system in which parameters are not optimal). If rocks drop off then its not coralline.

Here's some of my plating coralline algae.

Here's what a month worth of coralline algae is like.

Here's what it was on 14 Aug 03. (it was scrapped cleanly about 2 weeks before to keep the black acrylic background clean).

Well... let's just say... I gave up.

Sigh, looks like all of us got the same problems with coralline growing all over...its now threatening to smother my front glass view too....Oh man, wat to do....

Can someone tell me how come my 9months old tank never got such algae on its sides!!!???

Thought they look cool...Very natural...

Die coralline! DIE!

I find that giving them a blast of light of a different K rating does the trick to kill them.

I dun get it....Coralline Algae...I tot it is good then why would it be a problem in other schools of thoughts?

They grow on the glass and compete for calcium with SPS.

Thanks...

so it means that a FOWLR tank wouldn't worry about the coralline growing on the sides of the tank. Btw...what makes them thrive?

Am I hijacking? should I start a new thread?

[bawater]

good water quality,high calcium makes them thrive.

its the correct thread.
