Okay, so are we saying that random is good or full force is good?

Random flow is most important. With the Vortech like you have it is easier to achieve. With the non-controlable powerheads which only have one mode, being constant full power, getting true random flow is more of a challenge.

I think you can achieve random flow without spending hundreds and hundreds of dollars on vortechs. i think you can keep a tank full of sps happy with fixed power heads.

No flow "works" too, but its a variable definition. I would think with vortechs you are fine, at the very least I would get some hydorflows or some scwd's.

I have to move my K-nano when I do WC's anyway, so I move it around weekly. Its hard to get enough flow without clogging the whole nano with pumps, so thats my rationale.

I like the concept of the scwd's, if you don't have controllabe powerheads. They can recreate the alternating sequence.

so, it's about "bling"? vortechs are nothing more than jewelery for the tank? i've heard enough complaints about vortechs to say it's more like driving a hyundai, or a jaguar.....i think my hyundai will be in the shop less than your jag!

There is a lot more to it than the price/bling". I have owned both when it comes to powerheads and cars. There is a big difference.
My Vortechs have been solid. The only complaint I have ever heard of with vortechs is noise and about one guy who works there. I think noise depends a lot on which mode you are in. We will just have to agree to disagree on this one.
When I said, "sure they both work....." I meant on the lines of they both can get you from a to b.

ok...but can you at least agree that you can keep an equally healthy sps tank with or without vortechs? my stance that you can do this with budget power heads is true, is it not?

I don't have the experience either of you do in this, but I would imagine both can be equally as healthy, but varying levels of "success". As an extreme, not true example, both tanks never lose a coral, everything is very healthy, but the growth rates and possible color on one tank are much better.

There isn't much concrete data on the exact sweet spot for SPS growth and color, but most data points to high light, and high random crazy flow, which is better achieved using wavemakers. I have seen some really nice tanks which cite a 90x+ turnover rate and varying levels of directional flow.

Really not meaning to bash anyones methods or saying if you don't use vortechs, you aren't successful. Thats obviously absurd, im just playing the extreme ends devils advocate here.
