That sucks. Is nautilus a rebuildable? Did you dissasemble and thoroughly wash all parts? Cutting oil/rust preventing oil is all over these things when you first get them. Lemme google nautilus tanks real quick and I'll see if its maybe a mesh issue? I'm not familiar w/ them...Can I add that I truly HATE my nautilus (and I even bought the stainless tank when I bought it, yes it was different orders) . This is only the second time I have used it. First time...MOV..Double Barrel. ..this time Ahlusion Figian Nights....oh my holy hell, all I taste is "metal". I truly hate it! $50 down the vape drain. Put Figian in my beloved SmokGBC...I dig it! Totally.
