I started using Devour from Precision two years ago. Expensive the first two years but results have been amazing. All pond weeds and algae has been reduced 75%. We had a silt/sludge, knee deep, right off the shore for years. We were treating the lakes every two week with chemicals and not getting anywhere. Now it is back to the original gravel bottom that you can see golf balls 5 yards off shore. Going to switch to the devour/algae control product this year (don't remember what it was called). Quick to apply by throwing packets from shore line. No worries at all in irrigation pond like I would have from other copper based products.
