Thats what this fitting is for,How do you seal the probe in?
This is a good question. I've got my probe sitting in my "internal sump" so there is a constant pretty strong flow over it. I have found that when I calibrate it each month, it reads about 0.2 off but I don't know if this is due to the flow.Rolo said:Does the pH seem affected by the strong water flow? (filter on vs. off)
