Excellent product and great customer service

I have wanted one of your GLA CO2 systems for several years and was finally at point where I felt comfortable making the investment. I made the purchase, but not for myself. I gave this system to my Dad who also loves keeping planted aquariums. At first I think he thought there was going to be a lot of reading and research necessary but he said it was so easy to get setup! Thanks for answering my emails and shipping so quickly right before Christmas.
