Will my fish adjust to my flow increase?

[tim the toolman]

So I have been running 4 power heads in my 180 for its entire life 2x 1050 and 2x 1400 gph. I just picked up a coralife wave maker which adds an additional 2900x2 gph power heads. They do. It run 100% all the time but they ramp up to it 4 times a minute. The fish seem a little shocked by the change and my question is will they adjust to the flow change or am I just gonna **** them off and stress them out?
