My pond has been very low visibility since it was built 3 yrs ago, 1-2 inches. I took a quart jar sample too see what would settle out. After 1-2 weeks with no chemicals applied the sample cleared. The pond has also cleared a little, 6-8 inches. Since the sample cleared completely does that mean my clay is not suspended and I just need to give the pond more time too natrally clear? ( worried about my LMB and blue gill) cat fish are thriving.
