Thanks All, I haven't moved it around since mounting and flow has been the same which is 40% on counter sync mode with the neat wideflow guards; perhaps I will dial it down a bit. This picture was after feeding time and I haven't noticed any retraction of any of the torches. I have been using Tropic Marin Pro and the vat I am using is from 160g box; I transferred to a bucket so am not sure if it was turkey sourced and if that may be the problem. The salt does have dark residue in my mixing container, but I have been getting that since Nov. 2020 and TM told me it was excess Manganese. I was wondering about reproduction, but to be honest I haven't experienced that before, so appreciate that possibility. Appreciate all of your thoughts.
