Curious about others experience with this. I am currently manually dosing 2 part and considering either a doser or Kalk in ATO. Any feedback on thoughts of this approach or experience would be appreciated.
I have quite a number of these. The color is difficult to discern in the pic...it is gray. Almost 99% sure its a bristle worm...what concerned me today is that one of them appear to be within the skeleton of a button scoly.
