Jedi, those floating scrapers (Mag-Float) really do work. The Mag-Float people make two categories of scraper: one for glass, and one for acrylic. Each category has a few different sizes based on the thickness of your glass.
I just got mine from Petsolutions, and the little blister package said they were manufactured in the Netherlands. The magnets are pretty strong.
They do not scratch the glass unless you end up getting some grit (like, say, aquarium gravel) between the scraper half and the glass surface. For that reason, I tend to leave a 1" belt of algae untouched near my tanks' gravel bottoms, and use a Kent plastic scraping blade to finish that off, when needed.
In the beginning, months ago, I was really worried that I might suffocate my fish with my rudimentary CO2 setup. I just recharged it w/ fresh water, sugar and yeast (every couple weeks I do this), and it's putting out about 1 bubble per second with no ill effects over the past couple days. You could go with a 1-litre plastic pop bottle on a tank of your size (mine is only 38-gallon). A larger bottle means it can keep bubbling longer because it takes longer for the alcohol concentration in the fermenter to reach a critical point (where yeast stop fermenting) if the fermenter has more water volume in it.
I do check pH often, since adding CO2 usually drives it down a bit. I adjust carefully w/ a carbonate buffer.
I don't know much about Eheim canisters (other than they are excellent products, the Porsches and BMW's of the fishkeeping hardware world). I just had my CO2 outlet hose positioned next to the filter inlet of my HOT Magnum. That way, just as a bubble of CO2 emerges from the fermenter airline hose, it gets sucked into the filter intake tube.
You know those check valves that come with some air pumps? You can buy those separately. That's all I use. My setup is truly simple.
A bubble counter allows you to see how much CO2 is being put into the aquarium. If it's putting out a bunch of bubbles at a machine-gun pace, then you're getting a lot of CO2. If it is sedately showing a bubble each second, then you're getting not so much. That's all it does. I guess some have check valves integrated into them, though I've never seen one.
I don't have a bubble counter other than that airline house carefully positioned (using suction-cup airline tube holders) next to the filter inlet. I can visually count bubbles as the fermenter spits them out prior to them being sucked up by the inflow of water into my filter.
