Yes, I'm sure you've already added a standpipe to the emergency Herbie drain....and of course you have a gate valve on the primary Herbie drain....
I know you mentioned using filter socks...you could extend the Herbie drain so that it exits below water line in the sump. Because the Herbie drain doesn't allow any air into the drain, there is no bubbling or splashing when the water enters the sump below water line. You eliminate a lot of noise and salt creep that way.
