Just started my flush. My first time using a flushing agent . ran 2 gallons of water Through with 1 tsp of sledge hammer in each. manufacturer recommends 2 teaspoons I’ll move up Depending on how it acts to this dose. Runoff was at 568 ppm and 5.8 ph. I don’t know if I should have kept running water through Or if this stuff eats up the PPM’s Without overwatering I don’t know we’ll see. Open to advice . Overall she is doing well
