Innovative Marine Spin Stream Universal Nozzle

These do a great job at randomizing the flow in my IM AIO 20 gallon. Look great, easy swap. I did turn up the pump’s output, but they seem to be working perfectly with the stock pump.Regarding the noise: Yes, I was surprised and disappointed at the SERIOUSLY obnoxious clicking noise these made when I first installed them. I read the other reviews: Some said the sound went away and some say it never did.I can happily say the sound DID go away after about 2 weeks. Not totally, but about 98% improvement. I can hear them, but just barely and they don’t “click.” It no longer bothers me at all. Keep in mind that my tank is in a breakfast room in between the kitchen and TV room, so it’s located in a spot where other noise drowns it out and I don’t have to hear it constantly. If it were in my bedroom or somewhere I’m looking for quietness, then I may not have had the patience.

The media could not be loaded. I honestly was not going to purchase this product because of the reviews. I went with my gut though and bought it anyway. People were dogging this product almost every review at least reviews I remembered all were negative. So either they are or were lying. Or innovative marine really fixed all the kinks. As you can see... I literally opened the box and had it installed in less than three minutes. Using slow flow... I believe it's a tetra sp140. People said you need extreme flow... I didn't, don't. Switching to an ehiem compact on 600. I'll keep you updated. Silent effective immediately. And the price. More than fair for something that will last forever? Imo.

The media could not be loaded. I just set up a new Pico tank and needed a way to create waves without a wave maker. Works with my Aqua Japan AJQ-25.Pros: I have my stock water pump on full blast flow with this attachment and it's enough to get it to oscillate round and around at a satisfying pace and flow. It seemed to have choked back the flow very little, for me it softened the harsh stream the stock return nozzle was providing to the perfect turbulence of wave for my tank. There are zero dead spots in my tank now, and the wave pattern is random each time which I really like. Baby Helmet the current surfing clownfish can still speed into the current when he wants to without looking like he's going to blast out of my tank while breaking the sound barrier. My RBTA anemone, Zoas and Firework Polyps receive just enough flow to keep them clean and sway them gently. Overall super happy with it's performance.Regarding the noise, there is a very minor hum from the one I received. I honestly never even noticed it until I stopped to take this video, you won't notice it unless you sleep in silence and your tank is in your room. It's easily drowned out by tv, fans and day to day hustle and bustle of the home. I have an air pump on another nano tank that is 1000 times louder than this thing.Cons: The opening to feed the plumbing through the wall is a bit small on my tank, so it doesn't sit nice and even with the wall as I would have liked but that's to no fault of the manufacturer. It sticks out about 1.5 to 2 inches, but I figure will be less noticable in the future once I start my vertical zoa garden on the back wall You will experience GREAT RAGE trying to put the silicone adapter on. After I stuck it into warm water and tried gently twisting and pushing it together it was much easier. Rubber tip tweezers help too! Circular motions!

The media could not be loaded. I read a lot of the reviews, many of which claimed these were not loud and worked great, and others who said these for sure were too loud. The only good thing I can say about these flow randomizers is that they make me appreciate how silent my tank otherwise runs. The second I stuck this on to my out flow, I was like "dang, I guess I got a noisy one." Knew immediately they were going back. YMMV, but no way I was dealing with the rackety noise. I'd attach a video, but not giving this app access to my phone camera and mic--sorry peeps.

I didn't think Id like this as much as I did. the stream was really random and it would reach all the way across the tank.

This thing is cool and probably great for freshwater tanks. I tried to put it on my outlet to a small nano saltwater tank to more randomize the flow and tame it down a little, but it choked back a ton of flow.Chill freshwater tanks with like guppies or something, I'm sure it's great. And yeah there was some noise, but that'll level off and go away. I'm sure it's just my fault for trying to use it in the wrong application.

replaced my stock return pump that came with my 27g Aqua japan tank. I originally purchased the larger model not the mini thinking i could overkill on the flow. Turns out it was just a few mm too large to fit in the back chamber. So this review is for the smaller mini model. Have it on full blast for a night so far, all the equipment and adapters were included to make the install easy. Excited to have the feeder mode and adjustable flow in a controller. You can already tell the pump is moving water better and can see visible clarity difference for my messy cichlids
