ID this Algae
I have developed this Algae in both of my S/W tanks.
It is only on the glass growing along side the Coraline algae.
It started about the same time as the Coraline algae.
It is growing in these small circles only on the back glass which I don't clean with the magnet all the time, It scrapes off like the Coraline algae need a razor and comes off whole and brittle not like slime or dust.
The snails don't seem to have any effect on it.

I get paid for what I may have to do, Not for what I do!
