Spin Stream Universal Nozzle

Item works great. Low noise. Great wave maker moves a lot of water around for the size.

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.

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!

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.

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.

Edited to change review. So it's been a couple of weeks and they are now both almost silent. The nozzle is so large that the flow is really not that strong. Barely moves the hammer right in front. However since I do have a pump rated up to 1300gph,i turned up the juice on it and those spinstreams are spinning fast and the flow seems much better. However if you can get your hand on a accelerator this would be better for most. Because it fine tunes the stream. I'll use it for now but don't buy these unless they are under $15, like mine were, or if you have no other options. I bought two for my Jbj 45. Other sites advertise these at 20+ dollars, but they are barely worth $10. One is so loud I can't hear the TV over it. The other is not as loud but equally annoying. Ruins the whole point of a relaxing tank. I'm using this with the Current DC pump and there is not much for flow really even at 50% power which is pushing the rated gph limit these can take. Anything pump under 500gph will make this product worthless. Save your money, this is a garbage product.

Great for a smaller tank/AIO. I have a 15 gal reef where I didn't want to add another pump for flow so I got this. It works great as long as you have a powerful enough return pump. This will reduce your return flow so plan accordingly. I originally had a Sicce 0.5 and replaced it with the larger 1.0 pump for the return to be roughly the same flow. It is not loud as everyone is saying unless you have absolutely no other noises in your room.

Bon produit et emballage nickel

Good and beautiful product, gives a smooth and nice flow to you return in aquarium.

i do not bother doing reviews normally but credit due to a brilliant gadget, well made. silent and great for your plants.i bought 3 off them. changes the flow direction to a circular motion. after buying skimmers and flow pumps to give various flow in my tanks, costing over £50 per tank. .I replaced them with this attachment for my filters, i can now run my filters on full flow. I am going to buy more for my other tanks now as they look like they will survive the algae wars and pleco sucking.

cool gadget and good quality plastic give you extra wave maker from pump in to aquarium cheap solution extra wavemaker

Es fácil de instalar y como lo describe el producto trae 3 adaptadores para acuarios que no son IM. Yo la use en un acuario con un bulkhead de media pulgada y quedó perfecta. En algunos comentarios mencionan que es ruidosa, en mi caso el primer día si es notorio el ruido que hace al moverse, pero ya después de un par de días no produce ningún sonido. Recomiendo la utilicen con una bomba de buen flujo, yo la tengo con una de 500 l/h y no mueve mucho el agua.
