If there is any yellow, brown or green color, it might be mustard algae.

If no yellow, brown or green, then it might not be mustard algae.

Other than mustard algae, I don't know what else it can be.

It has a tinge of green. Closer to a dark green/brown.
You've been down the SLAM road so much you have this down to a science. If you wanted before closing, you could go back to SLAM level, pass the 3 criteria, then simply increase to MA level for 24 hours. That :should: take care of it should it be MA.

I’m not too worried about it. Given the crack in the fiberglass, I’ll have to drain the water before too long. I’ll just keep it under control until then and then go over everything with a fine tune comb while the pool is empty. I’m thinking about something like spraying down the entire shell with a chlorine/water mixture before filling it back up. Will think more about that when the time comes.

So I left the spot for another day and it did not change at all. Wouldn't it have grown if it was algae? Especially mustard algae?
