According the to the Tyree EG concept, he defines a low-flow, no light cryptic zone and a decent-flow, very little light filter feeder zone (in addition to the typical display with high light).
So I'm planning to put live rock in all three zones... but it has occurred to me that some hitchhiker could somehow dominate the dark cryptic zone or go after the feather dusters in the filter feeder zone -- in general compete where these zones are supposed to be refugiums for cryptic critters.
i'll be sending water from the sump, so it will have been through a filter sock before making it to these zones... but of course there will be plenty of DOM and other nutrients in the form of fish waste and coral food (phyto, roto, oyster eggs).
does anyone think common hitchikers such as bristle worms and vermetid snails could somehow dominate or negate the whole point of these cryptic zones? would i be better off using eggcrate (like bricky) or perhaps cooked marco rock?
thanks for any insights! particularly interested in hearing from any who's actually run a cryptic zone.
