Spirorbid Worms (counter-clockwise)

[Logzor]

I have a ton of these all over my tank. The underside of some rocks are almost entirely covered with these little guys. The back glass is also well covered in them.

Even my newly placed Koralia's are getting little clusters of them.

I noticed that in most pictures their spiral goes clockwise but mine go counter-clockwise. Does it depend on the hemisphere you are in or something?

Anyways, are these stealing calcium away from my lps and sps? I know they are harmless but in large numbers is it a bad sign?

My Parameters from last week are as follows

Nitrate 0
Nitrite 0
PH 7.8-8.2
Alk 9.1
Cal 400-450
Salinity .026

ive heard that its a good sign if you have them. it means your doing everything right. dont have an answer for the calcium sorry.

they wont really affect your calcium parameters since they are so small. if you really wanted two you could just scrape them off with a razor.
