Ok, I guess I was getting a little ahead of myself, because I have no clue as to what some of you guys are talking about. First of all, what did you mean by "buckle", DrBatty? And what are baffles? And what are bulkheads and what is a DIY system? I guess what I need to know is, what are all the things that you need in a sump, and what do they do?
I used a rubbermaid bin to transport water once for one of my big tanks. A lot of Rubbermaids are made with a softer, pliable plastic, which can buckle, or bend under pressure i.e. putting water in it. If I am mistaken and you have one made of hard plastic, you have another problem all together - it could crack...very easily. and believe me, you do not want 20 gallons of water on your floor. Plastic is EXTREMELY porous and can have chemicals in the plastic that you can't smell or see, which could leech chemicals into the water you put in there, causing a toxic environment for your fishie friends. This could also cause buildup of chemicals you use in your tank further down the road....also problematic. Ultimately, it will give you less control of your parameters.
I've attached an image of a bulkhead for you.
They are favored by aquarists to seal around holes drilled in tanks, sumps, or refugiums, allowing water to pass through, but not leak around the surface area of the tank.
A DIY system means a system you create yourself. DIY="do-it-yourself"
If you are looking to have an octopus in your tank, it would best suit you to put as much, if not all of your equipment in your sump so the octopus doesn't get at it. You don't need much in your sump, just a good protein skimmer [skimmers are the heartbeat of your tank, don't skimp on this!], a strong powerhead to pump the water back into your tank, some sort of filtration [that is always up for debate, and every aquarist prefers different methods], and a heater if your cephalopods are tropical.
hopefully this post is helpful to you, but if you want to see what other people have set up, you should check out the tank owners database! good luck!
