Hey all. I recently noticed do to making bigger batches that my pH down isn’t staying where it should. Use same as always 1/2 ml per gal and gets me right there. But I come back next morning and its like I never put it in?? I’m not using RO becuase I’ve been happy with my results with adjusted tap water. Is this why its not holding pH becuase its not RO? I’ve tried two different brands now… more recently TNB granules… same result???
Maybe @MDBuds knows whats up??
