It's definitely dinos after doing the coffee filter test. I'm going to head over to my friends house tonight and get a photo under a microscope so I can figure what what type. No sense in guessing, but I am doing a little pre-emptive strike here. Yesterday early evening I cut my lights off, and I'm going to do an at least 24 hour "black out." I put that in quotes, because I'm not covering up the sides, etc, so some light is penetrating.
I've been worried about overfeeding such a small tank (I downgraded from a 100 gallon tank volume to a 35 gallon tank volume, and only moved 3 fish over. I'm now no longer worried about feeding the fish. Good news is I only feed frozen (LRS) and everything goes in the tank (I thaw in a shot glass in tank water and then broadcast feed, so I don't think I'll have issues bottoming out nutrients.
I've taken my skimmer cup off.
I've slowly bumped my tank temperature up to 81, and 82 by the end of today.
I'm going to shout out to some buddies and see about getting some LR or scoop of sand to add to my display. I'm also going to grab some pods, a CUC, and some phyto, if I can find it.
I know I'm just throwing things at the wall and seeing what sticks, but I'd rather start chipping away than being idle. Whatever kind it is, it's very aggressive. I've already lost several valuable pieces.
So I'm barebottom, and most of this seems to be growing on the corals/frag rack. To be fair, I don't have a lot of exposed rock, as most of it is covered with corals. If it's open water dino's, then I'll get a UV, but I'll hold off until I have a proper diagnosis.
For what it's worth, the 12 hour lights off seems to have quelled a lot of the growth I normally see by now.
