That was me, thanks for the post! I did see that. Still didn’t make it clear for me haha. Do I want a sump that has the optional refugium, or do I want to go with the nice WB gate valve… it was nice the other day I called WB just to see if they could sway me over Red Sea. I got straight to a person no problem via phone, which Red Sea doesn’t even list a number at this time. That’s making me lean WB.
