I might be a little late on this, and possibly giving some bad advice, but if you dilute some really hot sauce (the kind of stuff you get at specialty stores) in a little water and spray it on the leaves of the plants, the aphids will probably leave it alone. It worked for deer and my mom's neighbor and when I was younger, it kept our horses from chewing on the sides of their stalls. Of course I may be advocating seasoning the salad for your aphids, but if the water jet doesn't work, this might be at least worth a try. Of course try not to get too much into the water. Luckily, Capsaicin is an oil based compound afaik, so it should hang out towards the top of the pond.
