So while cleaning my tube, the little glass tip on the top of my tree perc broke off somehow. Apparently the glass tip wasn't fully melted on because it broke off as a perfect circle as you can see below... So all I have to do is clog up the hole to stop the air flow. its such an easy fix and there are so many ways to do it i think but what is the best way you guys think? We are thinking either get a small piece of glass and put epoxy on it and use a long stick to poke it down and get it to stick or use clay on a stick and put it down there, then use a hot glass wand to push down to heat up the clay enough to solidify it. IDEAS?
