“I have a Red Sea Max S 400 and the built in sump requires 2 of these socks. I have purchased 6 of these over the last year and not one of them fits properly. They are a little loose and tend to float up out of there socket. Given that Red Sea have been the sump requiring this "special" size of sock, not allowing me to use a third-party product, the least they could do is make them a snug fit.”
