If my calculations are right, that's about 33x. 1640, plus 200 divided by 55.
I've heard folks are usually between 10 and 20x. Have you turned all those on yet and how does your substrate hold up? How do your fish seem to do in it? Do you have to turn them off when feeding. Sorry for the questions, but it may be hard to tel yu it's too much without knowing how the tank inhabitants and landscape reacts to 33x flow.
