While algae may be a common problem for large pond owners, pond weeds would rank very high as well. There are many varieties of pond weeds and it's important to indentify what you have before you apply any treatment.
Pond weeds differ from algae in that they usually have leaves, branches, or vine like extensions. Chara, which is an algae, appears more like a pond weed, but is treatable with copper based algaecides. Pond weeds usually require some form of herbicide to control them.
When using an aquatic herbicide on weeds, it's very important to treat any growth as early as possible. First of all, the plants are usually at their weakest stage early on, and a pond owner can often use less chemical to treat the problem.
A good resource of pond plant identification can be found at the follow web address.

There are other non-chemical options which can help with weed control.
Beneficial bacteria is not a direct control treatment for aquatic weeds however it may be useful in reducing the muck layer at the bottom of many ponds. This muck provides a very easy base for weed roots to take hold and once reduced, it may lessen unwanted weed growth.
Pond dye may be helpful at reducing unwanted weed growth. Pond weeds, much like algae, require sunlight to grow well. By limited this exposure in the pond, weed growth may be inhibited.
Weed cutters and rakes can be useful for removing pond weeds. It's not a bad idea to remove any dying vegetation before it adds to the organic load in the pond. Weed rakes make this chore a bit easier.
