Hello! I am a newbie with a 15 gallon well cycled planted tank, a couple of German Blue Rams, 5 cardinals, dwarf pleco and a couple of cory's I am interested in setting up a CO2 diffuser and ordered the Aquario Neo CO2 Diffuser from Co-op. Could not find any info whether I need anything other than tubing and an air pump. So when I hooked it up after soaking for 15 minutes in water, nothing happened. Think I am missing something! Forgive me of my ignorance! I Googled and saw that Amazon offered a kit that had a jelly like substance. Is this what I am missing?
Thank you for your kindness and knowledge!
