Thanks for the advice Mitch.
If I do decide to keep the dsb, I will leave it intact (if it's not TOO heavy). It sounds like things could get pretty ugly in there if I take it out, and put it back in again.
I'm thinking about skimming the top inch or so (hopefully mostly the aerobic, not-as-stinky-stuff) and using that as a "shallow sand bed" and either ditching the rest, or maybe cleaning some up and putting it in the sump as a refugium. If I did that, i'd put a light down there and get some macro growing - there's already a ton of macro growing in this tank.
It's hard to know what to do.... there doesn't seem to be a definate best option. I appreciate the reply though, every tidbit helps.
Ian
