Another problem you see often is the buffering effect of having two bodies of flow directed against one another, e.g. two powerheads pointed at one another from opposite ends of the tank. This not only reduces overall flow momentum, but creates shearing forces where the bodies meet. This uncomfortable zone is easily reflected in motile animals becoming stressed and/or feeling the proximity of these shearing zones (anemones will often vacate these areas).

hey albert whats your thought on the closed loop returns from the bottom, after thinking about it all day its soundig like my best possibility.my tank is not wide nor long...8.5" is tight, i can have 4 return lines coming out from the bottom with a inch of pvc buried in rubble, and i can have one large drain at the top.
it wold look clean without any equipment or pvc showing and i would still get a good turnover.
im thinking i could do one powerhead either pointed straight down from the feedline or straight across to the glass .....do you think if i added the powerhead it would cause to much turbulance or do you think the closed loop with all the flow rising is a good idea??
the tank livestock:
numerous suncorals on the bottom along with a carnation,feather star the gorgonians will be glued to the glass wall going up, and a dendro for the top of my rock pedestal(will show that later lol)
the cleanup crew you bring up now is a good point, im already having a hard time in my bonsai with the overfeeding and pods i can imagine ill have the same problem in this tank sooooo.......i wont have anyroom for anything that moves lol any ideas??
