Hello everyone! After some research, i've made up my mind to go with the Black leaf Elite breaker base! I've read good things about it and the price is not too expensive! My question... Do i need to buy anything else? I've read on the forum that people buy Ash catchers, pre-coolers, carbon filters... (??) -- do i need any of these for the black leaf elite bong? Thanks for the help! link to item on grasscity: [ http://www.grasscity.com/us_en/percolator-bong-ice-elite-6-arm-perc-beaker-base.html ]
