In a FW sump foam is not a problem, part of filtration, catches bubbles, and a greater volume for water reserve/ Water Level
This is another topic but if you are going to use s sump you have to choose which overflow you will use, My tank came drilled for durso style, I just changed from durso to a herbie style, I didn't know how much noise the durso made, the herbie is totally quite.
Drilling a tank your self is easy, so choose a overflow that works out best for you.
Good Luck
