SICCE Syncra Silent 5.0 Multifunction 1321 GPH Submersible Water Pump | Italian Made 105W Ultra Quiet Durable Aquarium Fish Tank, Fountain, Pond, Hydroponics, Terrarium Black | Freshwater & Saltwater

More powerful than I needed. Probably should have went with a smaller option. Even though my tank said 1086 GPH I have this pump set to half so I could have gotten the the 700 GPH pump. Quiet as can be. The feet don't come off easy like the Ehiem pump which was annoying about that pump and especially because it died in 9 months and was louder! Great purchase...

I installed in a Waterbox Infinia Frag 125, put the rubber feet on and used rubber suction cups around the outside to act as buffers or bumpers in case it touched the side, super silent, you never hear it! Had to close the intake to the lowest setting it’s so powerful, works great though!

I don't know what silent means to most folks, but this pump is loud. It made this really loud annoying hum. I returned. Went with The VarioS 6 from reef octopus. It's dead silent. Awesome pump. Be wary of other reviews.

For is size the pump is quite with low vibration, very good water movement. All these types of pumps produce heat but this is not too bad.

The pump is compact, powerful and very quiet. If submerged, the pump is completely silent. The pump is also user friendly- coming with adapters to fit various applications.

one of the best pumps I have owned! I have had no problems with it and it is dead silent! I have had the 3.0 version running solid for almost 4 years now and not one problem and it hasn't gotten any louder. I just clean it about every 6-8 months and hook it back up. It doesn't add any significant heat either.

I've been trying different pumps for my koi pond and most were louder than the water feature. I spent a lot on the Danner Mag drives and they were super loud in every configuration. The Sicce was my last try and I am completely sold. The pressure is great and it's almost silent. I'm running in on 3/4" line submersed. I think it will perform even better if I upgrade to 1”.

I purchased this pump two weeks ago specifically because it was advertised as being quiet. In fact, they even use the word "silent" in the name of the pump and they have a little graphic of a speaker with a line through it on the packaging to further push the idea of how quiet it is supposed to be. I've kept aquariums for over 45 years, and this is without a doubt, the LOUDEST pump I have ever purchased. It was so loud in fact that after just two days I had to buy another pump from a different manufacturer because my fish were getting so stressed by the noise levels of the SICCE pump and also because you couldn't sit in the same room and quietly enjoy the aquarium. It moved water well, but otherwise it's totally unusable because of the extremely loud droning of the pump. The new pump is now installed (a Reef Octopus brand) and it is absolutely silent.

No es tan silenciosa como promete, al final termine cambiándola por una vectra s2
