I have pressurized CO2 with a dual-stage regulator, Ideal valve with vernier micrometer, burkert 6011 solenoid, ADA bubble counter, and Danner supreme with fractionating impeller connected to my canister filter in-line for CO2. Two powerheads for circulation, and a drop-checker (still working on finding the best one). Out of all the research I've done, and the wisdom I've absorbed from Tom Barr and the other veterans on this site, CO2 is an area not to skimp on. I will be taking every measure possible to have a great CO2 system.
I'm going to pick up some HC tonight and will grab some root tabs to boot. Pics to follow later tonight!
It takes generosity to discover the whole through others. If you realize you are only a violin, you can open yourself up to the world by playing your role in the concert.
