Finally ordered one up. Can't wait for it to get here 
Put in a small 28g dual 1.5ish ID, 8/9 wrap in today. Reading .73 and tasty as hell. This tank kills on flavor.
But this thing DRINKS juice
That's pretty crazy, I'm surprised. I like my Bellus better than my aromas, and my MTs. But.... If I want to empty a tank quick, the aroma and MT kill juice quicker. The Bellus is better for flavor, and the construction of it is really good. I just like it alot...Received my black UD Bellus today. Threw some 2.5mm ID SS316l coils in there. First impressions: It's a nice 'RDTA'. I love the looks, very nice looking tank. Decent airflow. Good flavor, a little better than my precious Aromamizers. But this thing DRINKS juice, nearly twice the amount of juice as my Aromamizers. All in all, it's a really nice tank. I'm glad I have one, I also want an MT, but I don't think the Bellus will be dethroning my Aromamizers, but it will be in my rotation. Just my thoughts.
Unless you have a leak, this means it is producing more vapor than the Aromamizer. You could try turning down the wattage and tightening up the airflow.
I run dual 26 gauge, 6 wraps and .36 ohms is about right. I don't think your deck is bad.My Bellus has went to crap , I must have shorted it out and melted the insulators , they look ok but every build I do the ohms are not correct and it taste like crap. No matter how I wick it and coil it , currently have 6 wraps of 26g kanthal dual coils and it comes out to 0.36 should be 0.50 ish . Can't locate a replacement build deck anywhere online or a fix . Anyone have any ideas ??
