Dosed a vial of bioptim, per my schedule. This is only the 2nd addition of bioptim, since I’m starting with a 3 week schedule of it. Walked up to the tank a couple hours after I added it, and I am seeing polyp extension on a certain acro that I have never seen fully extended.

Here’s the coral on 8/17. That’s a week or so after I put it in the tank. Was in pretty rough shape when I got it, but has slowly been encrusting the rock over the last couple weeks. Regardless, polyps never showed much extension. This is the norm:
