I eventually started filling it with bleach in my sink, which bought me about a week before it was completely clogged again. Before MB7, it was set and forget. After MB7, it needed daily attention and completely melted down when I didn't have any to give for five days.

This is the part that makes no sense to me. I actually experienced the opposite with MB7. It cleared up mulm in my tank and sump, and my bio pellet reactor (Vertex) always worked perfectly, with no build up of anything. Plus I did a lot of research on RC about MB7 before using it, and never did I see your type of experience with it.

Perhaps adding the MB7 to your reactor made the bio pellets dissolve more quickly (worked too good) and it overwhelmed the ability to discharge the carbon laden bacteria waste, esp with it recirculating. Just another theory...

Oh, and what kind of skimmer do you have? How much gunk do you pull out in a week?
