Here's the deal. Go to walmart, get a 7 galon tub and lid for 6.00, go to a pet store and get an air pump for 7.00, some 1/8 in tubing, a dozen air stones, go on e-bay and get some hydroton rocks and 12 3" mesh pots, trace the Dia of the mesh pots on the lid, cut them out and presto, you have a bubbler less than 20 bucks, I bought the first one (49 bucks) and after seeing what it was, I made the second one.No one huh? Damn
