So after 5 tries, I am still getting no bubbles from my DIY CO2 setup. I don't really have the time to keep screwing with this so I've decided to go with a CO2 system that uses the same fermentative process. These are the ones that I've found so far:

or

I also found this

Anyone have any experience with that? It looks pretty cool but then again so did DIY

I am also considering pressurized CO2. My tank is a 55g and I think that maybe over the long run, it'll be more cost effective. I found this setup that seem sto include everything and isn't a billion dollars:

What do you guys think that I should do?

The 2 above are good but they are the same as diy co2, all it is is just premixed packets of yeast and baking soda. Plus they are only .5-1L big so they would not provide enough co2 for your 55g tank.

The Carbo-plus has been known to be a waste of $$ so ignore that product.

Pressurized is your best option. And will save you plenty of headaches. Though that system you linked above is great but the final price wont be..
So try and call local welding places and see how much they can rent you out a 10lb co2 tank for.
Then go to www.water-testers.com and get their Milwaukee CO2 regulator, they have it for the lowest price on the web. $84 shipped
You get the Regulator, solenoid, needle valve, bubble counter and tubing. Everything you need to get started.

Cool. I'll do that. To diffuse the CO2 from my DIY system, I was running the tubing into the intake of a fluval 1+ internal filter. Would that still be appropriate or do I need to get a specialized diffuser?
 
Is that the only filtration you have on the 55??

I never diffused through an internal filter but if the bubbles are remaining in the filter and or coming out as a mist then i guess its fine. Another option would be to get a limewood airstone for a diffuser. Or ofcourse if you have another canister on the tank then you can diffuse via that.
 
I kind of figured that I would end up going pressurized. Starting grad school in January and at $34000 a year, I'm trying to keep costs down but I figure that this will actually be easier to maintain and cheaper over time.

Get as much plants as you can + the pressurized. Have the plants grow fast and do plant sales every other week. By January the plants will pay part if not the whole amount you spent on the co2 setup.
 
Ok, couple of wierd questions... Why rent a canister as opposed to buying it? Is it really expensive to buy a canister? How long would a 110lb canister last? If I bought/rented a 10lb canister and the regulator/solenoid/bubble counter combo suggested, do I need anything else?
 
You can buy a new co2 cylinder online but once you go to fill it up at a local welding supply, they may only do swaps (you give them your tank and they give you a used filled one + you pay $13-25 for the gas itself)
So when you rent a tank from a welding supply you pay say $80 for the tank + $20 for gas. Once you are done with the tank and dont need it anymore you can return it and get your money back.

Depending on the cylinder you are looking for. For a 10lb tank you can pay from $85-100 + getting it filled. Unless you can find a used cheaper one on ebay.
For a pressurized setup you will need the filled co2 tank, regulator w/ bubble counter/needle valve and solenoid is good but its optional. The final thing would be a diffuser, but that can be as simple as a wooden airstone.

Basically, you don't have to worry about buying one, getting it tested every few years, getting a new one if ever need-be etc.
