Hey guys, so this is my first bong and so far I love it. Got it on Ebay for 30$: 9 Inch GonG, has an ice catcher, 4 percolators. I tried smoking out of it and got high as ever. So far I am happy with it, but since I know nothing about bongs I was wondering if this is okay for my first bong? Also, I wanted to buy an ash catcher for it and didn't know if this one will work okay http://www.ebay.com/itm/14mm-Ash-Catcher-Lab-Filtration-Labware-Green-/281475531823?pt=LH_DefaultDomain_0&hash=item41893fc42f Lastly, if i get an ash catcher how do I find a new down stem that will fit?
