In an unexpected (and questionable) move last fall, Monsanto retired their former aquatic-glyphosate brand known as AQUAMASTER and replaced it with; drum-roll please - "ROUNDUP CUSTOM".
Talk about confusing the market-place! Here we've preached for decades "Don't use ROUNDUP in aquatic sites!"... Now, that story has changed - sort of...
For what it's worth: There are numerous versions of ROUNDUP (XYZ) in the marketplace, not to mention multiple more flavors and concentrations of glyphosate under other brand names. Yes, there are disctinct differences between the various brands and formulations that exceed their "active ingredient" concentrations.
In short (and to my knowledge), virtually all but one brand-name of glyphosate labeled for aquatic sites contain 53.8% active-ingredient - and NO surfactant - so the addition of an appropriate surfactant (that is intended for aquatic sites) is necessary for maximized activity and performance on targeted plants.
ADDENDUM: Shore-Klear Plus IS labeled for aquatics and DOES contain a pre-blended surfactant. However, it is an 18% glyphosate formulation versus the 53.8% a.i. for most other aquatic-labeled formulations.

As usual, the one thing that is consistant is change.....
