This is what we do!! This 12 acre pond was treated with Floridone 30 days ago. We performed final dosage today and noticed it’s looking much better. In 2-3 more weeks this water body will be free of all submerged vegetation. What would this cost u might ask. Well. Considering the different types of vegetation and understanding the customers final expectations Floridone was our only option. Floridone cost approximately $2,000.00 per gallon. We measure overall lake size and take depth readings throughout to determine average depth before calculating the dosages. When using this paticular product we have an Aquatic Advisor name Kelly Duffie who has taught me most of what I’ve learned over the years by countless hours on the phone. a special thanks to this guy
