Trying to id this crud.I have read way too much on this and I really dont have much of a plan how battle it yet.Soo much conflicting info. I know the first thing is to try and identify it,but I am by no means a biologist. These are the best pictures i can get with a borrowed microscope and improvised cell phone . Tank is a 240g with approx 60 gal sump. it has been set up for almost a year so it it relatively new. roughly about 250 dry brs pukani rock and a minumal sand bed. I love this set up/system except for this nasty dino outbreak(i think) I am encountering. they seem to spin in a circles.
