good job buddy.
another question, which may seem kind of lame, but here goes. when the time comes to refill your co2 tank, you'll obviously have to disconnect the co2 tubing. would you plan on simply disconnecting it on the other side of the check valve (to keep the water from draining out on the floor?)
the reason why i'm asking is, i set up my reactor a few days ago (i know it's taking forever, but, new shed, new roof, new upstairs addition, new landscaping, yadda, yadda). as i didn't have the co2 tubing hooked up to the co2 tank, i was amazed at how fast the water would pour out of the co2 line once the reactor filled with water. for now i have the loose end of the co2 tubing sitting in the tank. i guess it depends on the type of check valve one uses, as to how much water pressure they can withstand and for how long, but it kinda makes you wonder how easy it would be for a large quantity of water to drain into your regulator should your co2 tank empty and your check check valve fail...
. i don't mean to be a pessimist but is this something we should be giving more thought to? maybe a couple of check valves just to make sure? anyway i'd just thought i'd ask your opinion.
hope all's well, thanks for the updated pic.
