Just got done making this today. Basically I used a 1/4" female T and three 1/4"->1/8" hose barbs to split the CO2 line. I glued this to a Hammond PCB Board enclosure that I had from when I made a DIY headphone amp. Then I through mounted the Fabco needle valves to the front panel and drilled holes in the back panel for the CO2 tubing to come out. After that it was just a matter of hooking up the hosing. I am using this to control CO2 on this tank as well as my high tech 10 Gallon.
So I have finally gotten around to updating the old blog...
Here are some new pics of the tank. The Giant Hygro was replaced with Sunset Hygro and in the foreground Hygro. Low Grow was added. In addition to adding these plants, I found the coolest Barbs I have ever seen, Oreichthys sp. "high fin" or Drape-fin Barbs. I bought all the last 3 the LFS had. I am hoping they get more in soon. This tank might turn out to be an all barb tank (minus the Otos)...
