Would you recommend DIY, I've never really researced that much but it seems to be doing great for you! I really like the driftwood too!!! 
 
Hello Thanks for the comments! The only thing with DIY Co2 is that it does get messy after a while and will only last in my case 3 to 4 weeks in my 55. But then the plants that I do have do not necessarily need a constant amount of CO2. I also have a high wattage on my lights and I do the dry ferts EI regime as well. 
 
I agree with most people that if you do have a heavily planted tank bigger than a 55 then pressurized C02 is the way to go. If you have any doubt check out pics of BK's and CFSINC's planted tanks. They are beautiful! (guys you owe me for that free plug there eh... LOL)
