I have used vortechs for so long that I don't necessarily have the first hand experience from that stand point but back when I first started I had a similar situation which really sold it for me. My first tank was just softies, leathers, Xenia, mushrooms, etc. It was very basic, and all I used for flow were some basic maxi jets. It worked fine but I wanted more and I found a 'new to me' product that rotated the flow from the maxi jets. I thought cool, mix things up but keep the same pumps, easy enough. Well, I almost instantly saw the corals open bigger, grow faster, and just plain look better. The Xenia and toadstool just opened and stretched out more than I'd ever seen them. Ever since I have made sure the flow in my tank is randomized in some way. The same applies to all corals, the ocean doesn't just push water in a single direction all day long, so our tank shouldn't either. Now, I have seen it in others tanks where corals directly in front of a steady stream are directly impacted and their growth is stunted or changed but I can't seem to find any pics of it at the moment. I will keep looking.
