ok, this is really is going to be a strange scenerio...I thought that a fly had gotten behind my tank and layed legs which looked like magets all over my ecosystem walls...well I tore it apart, and cleaned it out...needless to say these same things appeared again in the bottom of the ecosystem...nothing in my tank or where I have my macro algae and miracle mud..but on either side of where the water is siphoned out, and two or three where the water is returned to the display tank...what are these and are they harmful...they looked like magets, then got bigger and puffier with little hair follicles coming out the end...:notsure:
