I would go back to the lab and get them involved in this process. We can do a much better job of checking concentration and checking NVR that are left over in that material set to see if its reached its loading point. A lot of our chemistries get loading point at 5% which is high, but we want to make sure we stay below that limit. So, again, reach out to your manager and get a soil testing kit sent and sample of the bath. Get the lab techs involved and break down what is going on in bath.
