Coralline Algae?

[RiftWalker]

After a summe break where I left the tank for a month just with my maid feeding the fish, I return to my tank with all my creatures healthy and alive. I also have notice little specks of coralline algae here and there and I never saw it in my 9 gal which I had for 1.5 years. Is this a good sign or should I be concerned?

Keep in mind that my only successful coral have been 2 mushrooms and a gsp with a Zoa that’s hanging on. I had a candy cane and another Zoha which both didn’t make it after showing a lot of growth, especially the Zoa.

Coralline is always a good sign of a healthy tank

Sometimes we are the worst enemy because we tinker with everything. Nano tanks can be hard to keep stable. The coarlline is a good sign ! Took me almost a year after a tank crash to see my coralline take off again. Large water changes if not testing water before adding can cause tank to be unstable.
