Still a problem.
water now (tested at 0.00 TDS
), and have cut back feeding drastically.
I've done several PWC
's, 4 now of 25%.
I know only doing 25% at a time is a very slow way to remove anything from the water, each one only cutting whatever the problem is down by 25%. (100ppm of something goes to 75ppm, then 54ppm, then 40ppm, then 30ppm, and so on). Doing more than that is difficult without rearranging rocks and my soft stuff.
I'm thinking about using a chemical treatment, just for now, and then continuing to work on the source.
