Baffles for rubbermaid tote sump?

I'd say your best options to create the effect you're describing are either put the pump in a secondary container within the sump or place bulkhead fittings at the desired water level, plumb those to another container next to the sump, and use that container to house the pump. The cabinet Oddball posted can be used to achieve the same effect but the bottom drawer of the cabinet is the constant level chamber and the rubbermaid tote is the fluctuating chamber.

If you're gonna use baffles just buy a small glass aquarium. As mentioned above, the only real way to achieve this effect with plastic totes is to chain 2 or 3 of them together with bulkheads. And progressively step the level which the bulkheads drain down until you get to your last tote

I think i am missing something, but I'll give it more thought and see how it works because it seems like a cheap and effective solution. In the meantime, I essentially want to create a middle chamber that stays constant for a protein skimmer. Something like this is what I wanted to achieve out of the rubbermaid:

What your missing is that it simply will not work the way you want it to. Rubbermaid and Agrimaster poly tanks don't do well with baffles. For one it is a pain cutting things to fit them. Secondly not much sticks them. Let me dig up an old thread for you on someone on here that did baffles. Didn't work out well for them in the long run.
