Halo Reactor v2 leaking

[partychickmn]

I just received my order of a new Halo Reactor starter kit, and it was apparently sent with a v2 tank. I ordered a v1 tank, too, just to compare. Assuming that the v2 would be better, I used that one first. Worked great... until it didn't. For some reason, it started leaking out of the airflow adjustment thing, and it almost looked like it was leaking out of the bottom, too. No idea why it would work for a few hours, and then all of the sudden leak like that? I tried the v1 tank I ordered, too (have to make sure it wasn't user error!), and no problems so far. Any idea how I can remedy this leaky tank or what I could have done wrong? FWIW, I'm using 30/70 PG/VG, 20 watts, and the tank is a rebranded Freemax Starre (not the Pro version... just v2).
