This looks similar to most hair algaes, but with more detail on it. I think it would actually be quite pretty in another setting. I plan to rip it out by hand eventually, just curious what it is before I do so. I've also kind of left it alone until my chaeto grows out more since the pods love it and it's obviously exporting nutrients. It is growing on the rock that frag of zoanthids came on.
This may actually not be an algae, but I thought I'd post a pic here anyway. I haven't scraped it off the PH because my clown was seemingly hosting in it. Strange fish.
It re-covers the glass in 2-3 days. Brown, stringy, slimy, but wipes off easily with the mag float. I assume it comes back quickly because I do not run a skimmer right now.
And this third one scares me. Pics then why.
The rock in this trashcan has been dry for differing lengths of time. The least of which has been out of saltwater for over a month and I believe closer to 2 1/2 months now. The most recent to dry out was a couple large pieces of LR I removed from my tank that had been >90% covered in hair algae. The rock was set outside my garage on concrete to let the stuff die back in January. So the only water its seen has been rain. The lowest temperature its seen is 15F. It also had an inch of snow lay on it for over a day. Yet last week I decided to pick off what was left and some of the HA was still green. It was placed in a 32oz mug with an air line, some SW from my tank, and indirect lighting from the tank, just out of curiosity. It really bothers me that I may have a strain of unkillable algae around. The water that it's growing in now is just what I'd put in the trashcan to rinse the rock, 15-20 gallons of RO/DI + 1 cup of baking soda, 1 cup of CaCl and 1 cup of MgSO4. It has a SG of 1.003. Another explanation could be that it's outside and we had a massive pollen surge last week before the cold front hit the SE, so it could be something growing from spores in the air or that could just be supplying nutrients.
TIA, I'm sorry I don't read this forum much and I hope I provided enough information from the pictures.

You can also have attached to that small 3-4" long rock. Bubble algae, 10 or so blue with green skirt zoanthids and possibly the small feather duster/tube worm. I'm not exactly sure which rock it's growing off.
