DIY really only works on a very small scale, unless you want a ton of fermenting vessels, and even then everyone says it's a lot of work compared to the other option. I say pressurized 100%!
I've kind f heard that before. It's a Fishneedit light (so low end reflector) and directly on the tank. I must be doing something right, even though I couldn't tell you what. Very small biolaod, floaters in the front, small number of pond snails (that aren't breeding like crazy), 8 hours of light a day, LOTS of fasting growing stems, EI dosing. It's going well and I want to keep it like that.If you can afford a pressurized system, go for it. DIY co2 will be more of chore than anything else on a tank that size. I am actually surprised that you do not have an algae farm on your hands already. What fixture are you using and is it suspended above the tank?
You can say that again. It's definitely a chore. The larger the tank and heavier its planted the more of a chore it becomes. A lot of the times, you may not have time right then and there to make a new batch. You have to pre-make the setup. At this point, you might as well go pressurized. I can change my pressurized tank in 1-2 minutes after I have gotten a refill. It takes way more time to make DIY CO2. I'd drive 10-20 miles away just for a 5lb refill if I had to. Otherwise get a larger tank to last you longer. Only time I would do DIY is on a low-low/med tech tank with low bio load. But that's just me.If you can afford a pressurized system, go for it.

Get a drop checker and keep a good eye on it. Its going to take a few days to balance out the co2 in the tank.So most people are saying pressurized, how often do you have to trim fast growers? How easy is it to screw up? Like gassing fish or algae farming?
