If your dad used less than a pint of mixed round-up, did not mix it real strong (>3%) and he was pretty careful not to do a lot of over spraying of the pads you will not see dead fish. Some other small invertebrates could be affected with a small dosage.
ShoreKlear works pretty good. If you go that method I highly suggest that you use ShoreKlear Plus which includes the surfactant (adjuvant). Regular ShoreKlear has no surfactant. With the SK Plus you will not need to buy an extra bottle of chemical as surfactant. Timing can often be an important factor in how well the SK Plus kills weeds. Often it is best to spray the emergent weeds when plants are mature, flowering, or in later summer. At these times the plant is sending a lot of leaf fluids to the roots and the systemic chemical moves well into the roots for an effective kill. A respray may be necessary for those plants that did not get an effective dosage due to plant density or conditions.
