You'll need a pretty sizeable length of the 6" PVC. It takes approximately 2.2 gallons of bio-material to adequately filter 100 gallons of system volume. For a 300 and the plumbing, you're looking at 7 gallons of bio-material and that takes quite a bit of space.
diy canister filter?

His drawing says 6" x 72".
Just eyeballin' it that's about 6g'ish ?
Problem is he won't be flowing the whole thing cause its laying on its side. Can't pressurize it and have a 'dry' area too (horizonally).
Hey 12' of 6" PVC setting in the living room could look very artsy...maybe

i built a smaller version over the weekend. it is apx. have sized 4" x36" running at 250 gph. it is running on a 55 gal. i have lots of pics on the camera that i forgot to grab but will try to get on here yet today. the hard part seemed to be getting my end caps sealed. but wont be using screw on plugs on the big one. the small one cost $45 bucks for parts, glue, lava rock for media, hose, and pump. not to bad i think. i already have most parts for the big one just have to get the differnt caps a bigger pump and more media. will have pics up today or tommorow. thanks for your input DR. joe. i'll have more step by step once i set up pics to help tell the storyDR. JOE the avatars are of one of our race engines that we melted down melted 5 of 8 pistons and still finished the race
i think oddball hates me
either that or he is a negative nelly. not enuf media one could always plumb in more tubes. 4 wide under the tank 6' foot long thats 24' of 6" pipe bet thats bigger than any commercialy available system. the main goal here is to make a working system and if it needs more capacity thats the easy part

Wow, don't know where you got the "hate" feelin from. If you'd rather I blow sunshine up you whazoo and greenlight your original design, I can do that.
Are you planning on lava rock for the final assembly? Lava rock has only 34 sq/ft per gallon of surface area for nitrifying bacteria to adhere to. You'd be better off going with plastic pot scrubbie pads that will provide 370 sq/ft of surface area per gallon. They'll also allow for better water flow and have less stagnation contact points then lava rock.

The air injection should work. I've just never seen an application done like this to say with any certainty. I would place a little upward angle to the main body of the PVC canister to ensure most of the O2 expended air travels up the tank-return line past the end cap taper.
I have to agree with oddball here, the thing I don't see working very well is that the air that you are pumping into your "filter" is building pressure. You need to figure out where all that is going before you have a pipe burst, or a crap load of micro bubbles in your tank which just makes the tank look cloudy.
I like it! I would think that if you tilted the tube and put a pressure release valve at the top like this: http://www.plastomatic.com/arv.html That would solve your air buildup, however, I would wonder if the pump pressure wouldn't push the air right out the "return to tank" line. That's if you used a 2600gph pump as suggested, however, I think that's overkill. 8x T.O.? what happened to 2x?
Not to derail too much, but do you realize the current an 8x turnover would create in this tank? The water would be a turbid mess IMO. If you recall, Milkman used a 2400gph pump on his 600 and it was pushing the fish all over the place and he had to get a smaller pump.
It's more important to have an balanced turnover with contact time with the bacteria. I think an 8x T.O. on a 300gal even with 12gal of biomedia isn't going to give enough contact time with the BB to be effective. I'd go with a 600gph and use pot scrubbies like Oddball said.
