    I have a bunch of oysters below my overflow that has been in this tank from the beginning and quite some time in the old one. I wonder if I can move them to the cryptic zone once I have started it up. I have read a few related threads and think they should be able to live without light. Am I correct and do you think they will get enough water to filter in such a low flow area? Will the same things that applies to an oyster be applicable to mussels?

    I picked them up after a storm and I put them in the top sump after I realized they were still alive. I did not put them in the DT because I did not have space.

    They could be usefull if they do well as they are filter feeders.

    oysters and mussels are excellent for filtering out small suspended particles out of the water, they can be kept in the dark but generally need strong flow to get food to them..

    in all my diving experience i have wittnessed big oysters thriving under overhangs.. but in rapid flow..

    i think their biggest drawback as a filter is that they get forgotten and if they die they add pollution to the system..

    Thanks Les, You confirmed what i was thinking about. Too low flow is what I would have in my cryptical zone.
