The VorTech is great, but I think the 36" tank is a bit of a stretch for the single pump. I ran EcoSmart Tidal Swell mode Monday/Tuesday, and switched it to Reef Crest last night. The Tidal swell starts with small waves that grow bigger and stronger over a few hours before resetting, and the reef crest mode is totally random simulating the rapidly changing flow of the outer reef. I think the EcoSmart modes are much more effective with 2+ pumps working together.
I have a bubble coral that's really close to pump, and he doesn't seem to like the increased flow so far. I'll probably need to move him farther away, but my Zoanthids are absolutely loving the rapidly changing flow.
Adding this pump was just the first step in a whole slew of tank upgrades over the next few months. It'll still be just my 30 gallon display tank, but it'll incorporate everything I've learned since starting the tank.
