I'm currently using two DIY 2 liters co2 on my work 10g. While I'm reasonably happy with the output, I'd love to have the control and confidence that comes with a pressurized system for this tank. However, as this is only a 10g, I'd like to stay on a reasonable budget when it comes to this project. I'm wondering about how much I'd be looking at, minimum, for a reliable complete co2 system for this size tank. I'm more than willing to put in the work to piece it together myself to save money, just a matter of needing help finding ways to cut the cost back without compromising the build to the point that I'll have issues with it in the end. Any tips would be greatly appreciated.
