I got a Red Sea Max S650. I bought the Red Sea filter cups and use filter floss as my mechanical filtration method. My main issue is when I turn off the pumps to either feed corals, or feed the fish. When I do this, the filter cups pop out of their holders as the sump fills up, and 10-20% of the time, they fail to move back down into their spots. Has anyone else had this problem, and how do you solve it? I was thinking of weighing down the cups to prevent them from popping up and was wondering what is the best way to do this? Any suggestions are definitely welcome.
