What's your lighting, CO2 & substrate situation ?
If it were me I wouldn't even bother with a paintball setup and just get the full co2 setup. You don't need to spend the hundreds of dollars for a dual stage regulator that is full stainless. You can build a decent single stage regulator for around $100. It might be intimidating at first but once you have one you will realize that it's fairly simple and not as scary as it may sound. I built a single stage several years ago using a Concoa brand regulator that they use for beer kegs and bought a decent Fabco nv-55 needle valve and a cheaper solenoid and it worked flawlessly until I sold it when I built my current dual stage. Some people will tell you horror stories of single stage causing an EOTD but I personally never experienced one in the 4+ years of using it. Read through the co2 primer sticky and ask lots of questions if you have them. There is plenty of helpful people on this community that would be more than willing to help you through the process and before you know it you will realize that it's not as difficult as you might have thought.It likes a LOT of light, I figured that out. Before I bought a stem, everything you see came off one stem. I did some research on it. My plan was to attempt this plant with my set up. In hopes that I have put together a nicely balance tank. Im learning now that I have the substrate, I have the lighting, and ferts. Pressurized co2 would pick the tank up a lot. Im just limited on room. I would like to run the 55g and 10g off one co2 system.
Im just having a hard time pulling the trigger on pressurized. I want to start with a simple paintball set up and eventually put a full co2 set on this tank. I want to learn on a smaller tank. Is that good reasoning? Or am I making it harder than it is.
