I used two 1 litre bottles for a 36g. It will be pretty hard to do diy with a tank that big.
Dry ferts are generally bought online and shipped to you. Here's where I get mine: http://greenleafaquariums.com/aquarium-fertilizers-supplements/micro-macro-fertilizers.html. That'll last you over a year.i can't do dry fertilizers, i have no where to get them i live in the middle of nowhere.
Only thing I will disagree with here is using juice containers instead of soda bottles. Juice containers aren't meant to be under pressure, while soda bottles are.You could always easily add a 3rd bottle later on down the road if u had to. What worked well for me was 2 one gallon juice containers with handles on them. The handles made fishing them in and out of the cabinet way easier. I also kept spare undrilled caps around to minimize mess. I used a strong yeast mixture and rotated 1 bottle once a week during waterchanges rite before lights out. They produced bubbles within 30 mins Max because I activated the yeast for 15 mins in warm water with a bunch of sugar before adding to the bottles. Another thing I thought helped was to fill the bottles with warm water when making the mix.
I have actually gassed fish accidentally with DIY co2 which some people have said in the past is impossible.

I use two 2 liter bottles on a 65 gallon tank, but with low light, around 20-25 micromols of PAR. You probably have low medium light. I think a pair of 2 liter bottles will give you very noticeable results, and you will for sure need to begin dosing NPK to keep up with the increased demands of the faster growing plants.
The problem you may have is that it is hard to keep the CO2 production reasonably constant, even with replenishing one bottle per week. That may trigger some algae growth.
Are you sure you read the whole thing? I'm pretty sure there is only like one of the fertz they don't ship to Canada b/c it's illegal to do so. But all the others you would need can be shipped there. I'm pretty sure.nevermind... they can't ship to canada
