Since you will be running a low tech tank, which means low light, and no CO2 injection, an agitated water surface would not be a problem for your setup.
You can dose excel with a HOB filter. I dont see why not.
As for low light plant that will grow tall, I would suggest you to get a amazon sword, any sword would do the trick. There are also vals italian, which is my favorite. These plants will sure be a easy plant, requiring only minimal light and care.
