i use a neptune controller to cycle them. the tunze guys at RC said 15 minutes max. my understanding is that the new 6055 with controller will do pulse, wave back and forth, etc with no delay...i like the sound of two streams pulsing back and forth, with a soft startup that builds in intensity then tapers off real quick...sounds wavey to me. ive had good results so far. do you guys believe in the random flow thing or just flow as in one vortech and thats it, same flow thru the tank forever, no changing it up.
i want the lower profile of the vortech, one on each side of the tank doing the same thing, cycling back and forth every 15 minutes...
