Pond Boss Forums INTRO New Forum Member Introduction NW Ohio pond maintenance

As Sherwood mentions above and I also think your first steps should be to know exactly what problem rooted plants you have and what basic type or types of algae you are battling. There are many, many different types. Try and determine what algae and weeds are problematic to your pond.. Not all algae and weeds are created equal.

One does not go to the doctor and say you are battling sniffles and body aches and expect him to prescribe proper treatment. For good treatment the doctor needs to ask pointed questions and / or have tests to determine or see what is actually causing the "sniffles" and body aches. Diagnoses is key to a solution.

"Algae and weeds" do not really give me much information. I have many books of different algae species and pond - wetland plants "weeds". IMO different plant species need different treatments because they have different vulnerabilities to different treatments. Some treatments work much better than others which is one reason you are here asking for help. Wood County Soil and Water Cons District had a pond clinic this spring. That would have been a very good place to start.
