White Patches on the Glass

[Jey Christopher]

i am noticing some small white patches in the Glass. What are they?

 

[Jey Christopher]

Zoomed a bit

Not sure but it looks like calcium precipitating out of your water. Are you dosing calcium and Alk?

No , I don't

Sponges?

 

[dvanrij]

Do they scrape off easy?

 

[C. Eymann]

The start of coralline algea is my guess.

 

[Jey Christopher]

i

The start of coralline algea is my guess.

if so, i should not scrap em then

 

[AdamB]

Yes .. coralline . Maybe that has died since it looks white. Is there much flow where this area is located ?

 

[Jey Christopher]

i would say very less flow. i am seeing them for past 3 days only

 

[AdamB]

Okay. It’s dead coralline if it is white . I’ve had coralline do that on glass when coralline first started growing in my new tank .

what should i do now

 

[AdamB]

Just scrape it off. No big deal.

 

[Jey Christopher]

I have been doing it, it keeps coming

 

[AdamB]

If you put more flow in that area coralline will not attach. I have to scrape coralline off my glass every month in low flow areas . I notice you have it on your live rock and I assume your tank has been running for a while?
