Coraline algae on rocks.

[DUCADOS]

Understand that once coraline algae exposed to light when without water it'll turn white.

Had just experience it yesterday only.

Is there any help to have the coraline grow back again on the white area?

Bro, the coraline is dead and cannot be revived.

just leave the rock in the tank and wait for new coraline to grow.

Coralline Algae must be physically brought into your tank in order for it to reproduce and populate the various surfaces.

Coralline Algae can be introduced to your tank by:

Coralline covered Live Rock

Coralline scrapings from another tank

Commercial Coralline Algae starter packages

The more types of Coralline (green, pink, white, purple, red) that you add to your tank, the more you will see growing on your Live Rock, substrate and aquarium walls. Once you have some Coralline Algae in your tank, how do you get it to reproduce and spread throughout your tank? One simple method is to turn off all tank filters and skimmers, leaving any powerheads running. With a single edged razor blade, scrape the existing Coralline off the front and side tank walls. The water current generated by the powerhead will spread the Coralline scrapings throughout the tank where they will continue to grow. After an hour or so, turn the skimmers and filters back on.

So u mean the white part cannot revived but it will be covered by new coraline again?

Meaning new coraline algae can overwrite the white thing?

White part cannot be revived. It will only be covered by coraline algae if you have coraline algae on your other rocks and you place this piece of rock next to them. If all the rocks in your tank do not have coraline algae you will not be able to get any coraline algae.

Ic... But this pc of LR itself already fully covered with coraline just that little part is white only..

If only a little part is white and the rest of the rock is covered with coralline algae then no issue. The coralline algae will grow over the bald patches.

kind of disagree leh....

I know seeding kind of speeding up the purple growth.

But even if you have just a tank of dead rocks, over time once the water condition in right, coraline will eventually grow in the tank.

Pls correct me if I am wrong.

Nope doesn't work that way with coralline algae...

You need to seed the rocks with coralline algae for the coralline algae to grow. If you have all dead rocks with no coralline algae on them, then you will not be able to get any coralline algae growth on the rocks in future either.

Oh ok. Glad to hear that. Now I can at least dun need worry so much haha...

Thanks anyway.

Coraline algae can hitchhike on liverock holding corals, maybe that's how jacky got coraline from dead rocks.

Coraline can comes with rocks that are dead.. you dun have to necessarily seed them... seeding helps to speed up the growth as they will be able to anchor themself over all your rocks...

Still find it hard to accept. I have coraline growth on my tank walls. So are you guys saying saying that because I have coraline on my rocks, that is why my tank wall start to have a spot of coraline growth? Sounds a but far fetched.

My rocks are all 2 inches away from my tank walls.

Actually I don't know who is right... cause my rocks came with coralline to begin with... But I wouldn't be surprised if the algae got some spores or something that is suspended in seawater so no need contact to spread...

I agree with bro kanegan say.
