QUICK UPDATE: I was able to get my CO2 tank filled for $8 at my local beer distributor. This is great news for me since it's only a minute or two down the road anytime I need a refill (beer or CO2). haha!
Also, I'm in the process of purchasing materials for a Rex-style reactor. Hoping to have this built over this coming weekend. I'll add a few pix once it's completed.
Lastly, I need to purchase substrate and a light and I'll be ready to get this puppy up and running. Making a decision on a suitable light for a 40 breeder has definitely been a bit of a challenge due to the width of the tank. More updates in the near future!
