White spots on my rockwork

[bing_ph]

My tank has been running for 6 months now having put it up last Sept. 2016. After 13 weeks of cycling I started putting in corals and fishes. Todate all are doing okay.

Did my water change this morning and I noticed white spots on my rockwork. First time to see these and got myself worried. Can any body help me identify what these spots are? Something wrong with my tank? Just checked my water parameters and all are within the required range. Good or bad?

It just looks like something is eating your coraline algae. Do you have any urchins?

I don't see anything that looks alarming. Are the white spots new?

Just notice these spots this morning...am not sure if they have been there for sometime. I really hope it's not alarming.

Thanks for replying.

Do you have snails/limpets? If yes, what kind? Do you see any asterina starfish?

No urchins in my tank...placed new astrea turbo snails in my tank last weekend...dunno if they are the ones eating up on the coraline algae...

Thanks @wkscott

Just added turbo astrea last weekend. Do you think they have caused it? I remember placing these snails on top of the rockwork when I got them.

Thanks.

Have you checked your alkalinity. If the alkalinity is low, the coralline algae could be dying.

Dang, you quoted me before I edited. You're fast. I figured I'd try to sound less like a caveman. LOL!

Do you by chance have a picture of the snail?

Checked my water parameters last 3.15.17 and alkalinity was 9.3 dKh / 3.30 meq/L using a Salifert test kit. Will check alkalinity today again.

Thanks.

Here's a picture of the snail in the glass...

Got me really worried put here and been monitoring replies from you guys ...

Nah, that's an astrea snail. They're fine.

 

[bing_ph]

Nah, that's an astrea snail. They're fine.

What could be the culprit?

 

[AllSignsPointToFish]

Nope. I highly doubt it. They're only dangerous to algae and bacterial film

Should i be worrying about these white spots?

Might be Rock Ich. Better get those rock into QT.

I would not be. They look like areas where coralline died or was eaten. What is you lighting setup like?

 

[Sycoticrealm]

High Nitrates can kill off some coralline and sometimes it just dies off a little bit at a time if you remove a rock and expose it to air too long.
Coralline can be fickle but I don't see anything wrong to be honest the picture very bad so it hard to tell.
Focus your camera before taking the picture so we can get a clear look it could also be some of those one worms that form calcium tubes I can't remember the name for the life of me right now though.

 

[Sycoticrealm]

Spionid Worms that what I'm thinking of it like a sand like tube.

Am using kessils 360WE with max intensity of 40% and color of 60% ramping within the 10 hr photoperiod
