[Yep, those anemones and MJ intakes seem to have a mystical attraction for each other...
Since my MJ1200's pickup so much macroalgae trash, I started using the foam filter covers designed for Mag3,5,7 series. Works well and is amazing how much stuff the foam filters catch. I keep extras on hand so I have one in the vinegar for cleaning and one on the MJ.
Cleaning Tip: for macroalgae, bleach just nukes the cell structures so they kinda 'melt' away whereas vinegar pretty much leaves the macroalgae intact, even at full-strength. The down-side of the bleach is that if you leave the foam filter in it for several days to soak, it will deteriorate the foam into a very weird gooey mess. Overnight is fine though.
As far as hanging the MJ's, use the hook hanger supplied with the MJ as the suction cups just don't seem to function as well as we would hope...the hook hangers do well, however.]
