I just wanted to thank you guys for this incredible thread! I am in the process of setting up my first planted tank (I have 2 reef tanks and I used to keep African Cichlids many years ago) and have bought everything except the CO2 injection and lighting. I came VERY close to buying the Fluval Pressurized CO2 Kit, but the reviews were iffy and refill CO2 cartridges are expensive.
I am going to order the parts tomorrow and will work on putting this together next week. I will post pics when I am done.
Any thoughts on the inexpensive Adapter/Gauges available on eBay?
Ebay link was removed, but they are the "all-in-one adapters with the gauge built right into the unit. Description is:
"THIS LISTING IS A DO IT YOURSELF ADAPTER TO CREATE CO2 INJECTION SYSTEM FOR YOUR AQUARIUM / PLANT TANK FROM A COMPACT SIZE CO2 TANK THAT CAN BE REFILLED. FITS ON ANY STANDARD PAINTBALL CO2 TANK AND CAN SHUT THE TANK ON AND OFF WITH KNOB ON TOP. THIS ADAPTER INCLUDES 2 OUTPUT PORTS, 1/8 NPT, AND A 1500 PSI GAUGE INSTALLED IN ONE OF THE PORTS (WITH LOCTITE). REQUIRES, DO IT YOURSELF INSTALL, OF YOUR CHOICE OF SIMPLE ON OFF VALVES (CAN BE PURCHASED FROM HARDWARE STORES) AND LINES RUNNING TO YOUR TANK. ADAPTER ALSO FEATURES 2 O-RING PIN VALVE DESIGN AND DEGASSING WHEN THE KNOB IS UNSCREWED"
Trying to get my hands on a "free" paintball CO2 tank, otherwise I will pick one up next time I go to Pennsylvania or New Jersey.
