CO2 in Michigan

[JIW126]

Just wanted to let anyone in Kalamazoo, Grand Rapids , or Lansing know that if there looking for CO2 Horizen Hydroponics has the best prices I've found. The have a special going until the end of November on 20lbs exchanges for $6 and I think their regular price is $18. I was paying $16 for 5lbs refills at the fire suppression store.

Actually I took my 5lbs tank into Horizen 2 weeks ago to exchange it for another one. The didn't have any 5's so they gave me a 10lbs and all I had to pay was the $6. My system has a leak so I went back yesterday to exchange my 10lbs and they gave me a 20lbs again only charging me $6. So back ally I've upgraded from my 5lbs to a 20lbs for $12.
