ok, so i built a little jail cell from egg crate for the duncan. it kept bob (the clown) out but for whatever reason the smaller fish all HAD to be in there as much as possible. i think they find it interesting so that was annoying but not harming the duncan in any way.
but after a day or two, i started developing cyano within the eggcrate structure and only in there. as if the 3/4" squares were inhibiting enough flow and not allowing detritus and food, etc to escape somehow. it also lessened the light entry as i had a piece on top as well and all in all the duncan was not happy and looked worse.
i took the jail cell out. moved the duncan to the far side of the aquarium and bob seems to not have located it yet or just did not care to bother it anymore.
bob is now interested in the bubble coral and rubs and nuzzles against it throughout the day. the bubble coral seems to tolerate it well enough and does not retract or really react in any way unlike a few months ago when it would completely close up. for now, this is good.
lastly, i got my new vortech mp10 and installed it.
i have one low and to the kitchen side of the tank and one high and to the living room side of the tank. i then created the master and slave relationship between them with the wireless RF feature and set the low's local speed max setting independent so that even if the upper (master) pump is full blast, the lower (slave) pump will only go so high as to not disturb the sand bed with their incredible undertow ability.
it was almost within 24 hours i saw really nice improvement in extension of corals as they swept side to side and everyone seems much better with the addition. i really am a big fan of these vortechs, their design, and programming!
