Dinos I think

Raising nitrates is not helping. Acceptable are .05. Not to say 5 is high but not desired especially for many corals. Pics are very blue to tell anything but still appears as cyano which also can bubble. Dine will be golden brown and sliky stringy with bubbles almost representing snot

Here's some pictures, I found a pair of yellow glasses and it seems to help with the blue.

Best would be microscope. Or if you grab some sand with brown stuff and put it in a cup, mix it, see if it forms strings after like 15 mins. If it does probably dino.

So I tried this tonight. Grabbed some sand with dinos, put in a container, shook, strained through paper towel, and left it under lights for a few hours. It took about 2 hours to get to this point. What do you think?

Doesn't look like it. It was really rusty brown for me.
