ID help

This rock has been underwater for months with thermometer off and with salinity sitting high around 40ppms while I wait for my tank top to be made. It's not dinos or cyano, it looks like green coraline or sponges, but the tank isn't mature enough?

I know someone here can ID

Can you get a clear pic under white lights?

 

[phixman]

Yes, I hope these are better

Does it come off your rock easily when you touch it? Is it hard and encrusting? If the answer to the first question is no and the answer to the second question is yes, then it is more than likely green coralline algae. Not as common as the red or purple but still nice!

hmmm, I'm just surprised coraline is growing in a tank where salt is likely 45ppm with not much water movement, low temp , no light and return not running.

Welp it still is an algae lol. Maybe green varieties prefer these conditions for I know. I have a small amount of green coralline on the bottom of my rocks where there is little flow and light

Coralline algae isn’t too hard to grow as it doesn’t require much light or water flow. Some types can grow in brackish or in hypersalinity environments.

Good to know, thanks guys
