What about a square, divided into thirds using opaque barriers, with the two outside thirds as living quarters and the middle as your trial space? Then you could create a flow-through or recirc system with the water easily moving throughout the setup by positioning two powerheads in the trial section (assuming your movable doors from each living space were permeable - some kind of grating (not too fine of course) would be ideal), where the octos can't normally get to them to get into trouble. See attached rough schematic, with boxes for powerheads and arrows indicating flow. You could remove the powerheads during use of the middle section. You would only have to worry about positioning the powerheads out of reach through the grate...

Tintenfisch,
That's exactly what I was condering for the square sectioned off tank...Does anybody have any experience with chemotaxis and different behaviors founded on octopod chemical detection of another individual? I'm only concerned the animals might behave differently if they pick up on another individual who may be a threat to their territory. I bet if I thought out a few well placed overflow boxes and utilized this powerhead system we could keep a decent amount of water circulating....

Another quick idea reflection...I'm thinking this box should be about the size of three ~35-50 gallon tanks placed side by side...will adding more than one octopus to the overall tank cause me too much headache to bother?

Thanks!!

The one problem I see with this tank setup will be observation. You won't be able to see very well from the top, and looking from the sides is going to be diffictult since your trials area is in the middle of the tank. The following might be better for observation, and still within the same shape. I'll have to think about adding another.

Pipsuek (et al.),

Does it make any huge difference that there would only be an inflow and an outflow in each living quarters section of the tank...in other words is it alright with cephs to only have half of the "system." I suppose I could make the walls permeable but opaque so the subjects couldn't see through and notice each other too much...

Thanks again!

Your already talking about a large volume of water, to which your going to add a sump? I would think that the size of your pumps is going to be pretty important. I really don't have any experience with that, I just offered my suggestion on the layout because I am constantly concerned with spatial problems.

Thanks again for everyone's help, we went and met with a LFS owner yesterday and I think we've hammered down the tank design with movable chambers and the like. Right now we're in the gear-listing section of the study, and I'm having trouble finding information and understanding exactly the gph needs of a protein skimmer. We've going to run two 125-150gallon tanks on a single larger sump, but all of our calculations using "Rule of Thumb" conversions result in our using a HUGE protein skimmer with massive output. Is there a way around spending $650 for a protein skimmer attached to a pump capable of outputting 1000+gph? Does location of the skimmer make any difference in the needs of the pump? I know we need to turn the water over many times per hour through the sump/filter, but is this also true of the skimmer? On a side note, does anybody have reccomendations for a larger setup that works well for skimming purposes?

Thanks in advance, I've already gleaned over the sticky thread many times, just looking for experienced advise in particular about larger scale operations!

I have NOT tried it but I have seen several posts where people run multiple skimmers and am throwing the idea out for others to comment on the advisability.

Tank Schema

Here's a picture of what we've worked out....Disregard the canister filter, I think we have enough via the micropads (Correct me if I'm wrong!)

Again, everyone here has been as helpful a resource as I've come across!

Don't take out the canister filter. It will be critical if you run into an inking dilemma. The design looks superb though, it will really be something else.
