These popped up in my established display tank recently. On the sand and a little on the live rock. I'm guessing from changing lighting from Radium halide to Philips Coralcare led. Plumbed in frag tank running no sand has no sign of these. Lighting on frag tank is a kessil a360we running 50/50 color and 100% intensity. Could the whiter light from Coralcare have brought these on? Nutrients were on the low end with no3 being ~ 1- 2 and po4 ~ .04. I'm sure this could have a play in it as well.
Sorry for the terrible pic. Taken from my phone on a low budget microscope.
Any help would be greatly appreciated.
Thanks
