I use the Sicce 1.0 as well, on my Nuvo 10. Replaced the IM spinstream with an RFG and was amazed at what happened. At the time I had red gracilaria filling most of the tank, and the randomness of the water movement was greater than the spinstream. It was still in same direction of course, but the tendency to collect debris in corners was really minimized compared to the stock pump and spinstream.I use the Sicce 1.0. I guess the additional flow helps as I can water the polyps move.
I think you are right. I think these are a fantastic equipment upgrade for nano tanks with higher rated pumps. My back chambers are 80% mechanical filtration so a high output pump paired with these RFG and I keep my tank clear of additional wave makers and powerheads. I don't run these on my 40B as the flow through my return is less than what is suggested by the original designer.I use the Sicce 1.0 as well, on my Nuvo 10.

I suppose it is specific to this small of a tank with this powerful of a pump. It might not make that much difference, if any, in a large tank, compared to powerheads.
Not a good experience....I bought one of the VCA ones as pictured and it broke literally as I was installing it.
Love this product. Just be careful when removing can break or crack. Mine is cracked but still working fine. Just have to be careful when moving the tip so that it does not come off.These Random Flow Generators from Vivid Creative Aquatics are so affordable and effective I thought they deserved a QOTD feature! Plus we can talk about other ways to get random flow!
What are they? This is from the VCA website: "The Random Flow Generator® Nozzle. by Vivid Creative Aquatics can dramatically change the way water moves around your aquarium. With the RFG Nozzle you can produce a more natural flow pattern while also simplifying your flow solution. The RFG has not moving parts, which means it is reliable and durable in the harsh environmental conditions inside your reef tanks."
So let's talk about them and your experience!
1. How many of you are using or have used a VCA Random Flow Generator and what are your thoughts on them?
2. What other ways have you been able to accomplish "random flow" in your reef aquarium?
To be fair, anything you add to your return line will reduce flow to some extent. If you stay without our Suggested flow ratings (each RFG has them) then you can expect to see about 5% at the lower end to around 15% throughput loss.is this the thing that cuts your flow in half and then doubles it?
