If the sump can handle the back flow, there is no need for a check valve or any other device. Just because one person “recommends“ something doesn’t make it needed. No Red Sea tank needs one in a stock configuration.
As a matter of fact, I prefer the water volume decreasing in my tank when I shut off the pumps. This way I get a lower water level in case a fish tries to jump while I’m working in my tank.
