Hi all. New to this, and I'm getting everything set up. Tank cycled and I've added a few fish and corals. Today I tried to add a Red Sea Reefmat, and a Reefdose. The mat is connected fine. But the dosing pump has no connection after I went through the initial setup. I figured I'd just uninstall and reinstall, but it won't let me remove the device. Anyone experience this? Thanks!
