Refugium Algae - Pic

[hermitage]

I was away for the weekend. Upon my return, this algae has trippled in qty in my refugium. There were a handful of "leaves" that I could count, and in 2 days it has grown like wildfire.

The only thing I changed when I left on Friday, was I increased the dark period of my refugium lighting from 2 hrs to 8 hrs.

Any idea if this algae should be removed? or should I just let it grow?

Caulerpa sertularoides maybe?

Thanks all

I would leave it.
