I have a Provari, and an AeroTank. I've ordered the hippo V2 ring to get that straight cylindrical look. I plan to leave it on with all my tanks. I'm wondering though, how it will work when I put a tank on it with Airflow control already (eg AeroTank, nautilus). Anyone tried this? Did it work ok? I'm figuring you would just close one of them almost completely and manage airflow with the other if possible. I just don't want to have to take off my hippo everytime I use the Nautilus or Aerotank.
