I dont know anything about RBAs and RDAs except what's posted here. I'm tired of the muted flavor of my carto tank and I love the taste, but hate the inconvenience of dripping. Is a RBA/rda for me? If so what do you recommend? My requirements are: pyrex tank, doesnt leak, straightforward setup. Mesh I think is preferred over silicone. I read that the Zen leaks, do all genesis style leak? Please help! Thanks
