SICCE Syncra Silent 1.5 Multifunction 357 GPH Submersible Water Pump | Italian Made 23W Ultra Quiet Durable Aquarium Fish Tank, Fountain, Pond, Hydroponics, Terrarium Black | Freshwater & Saltwater

Excellent water pump for replacement of fulval flex 32.5 gallon aquarium. It was an upgrade to the old pump that was not moving water that effecient anymore. Actually I wish I would have upgraded earlier to this pump. It fits perfectly in the back compartment of this aquarium. And it moves the water better than the stock pump that comes with that aquarium kit. Easy to assemble and to set up. It is also a very durable pump and really well constructed.

Works amazing, and so quiet!

Have one of these in my 38 gallon aquarium and has been going strong for the past 3 years. Recently picked up a 2nd to use to mix my saltwater and to used as a spare for just incase. The knob to control the flow is a bit difficult to turn.

Bought this model considering even expensive for longevity but the packaging is missing a O ring which is for connecting hose connection see breakdown picture. Otherwise quality is good and hopefully I can find O ring.

This is my second SICCE pump. I use these for pumping saltwater from a 5 gallon pail into my aquarium when I do regular partial water changes. This is much easier than lifting several pails and carefully pouring the water in. I bought a Syncra Silent .5 a few years ago based on my best estimate of what I would need. I underestimated and it was just barely powerful enough to lift the water 4 feet to the aquarium rim and was kind of slow. I finally decided to get a more powerful pump that would have no problem with the 4 foot "head" and which would pump a little greater volume of water. This new 1.5 does exactly what I wanted it to do. The specifications appear to be accurate as it has no problem with the 4 foot lift and now empties the 5 gallon pail more quickly. Both of the pumps are easy to use and, because the case and impeller are plastic, they are not damaged by the salt water.

Model 2.5. Impeller rattle. This silent pump has a horrible impeller rattle. It's a far cry from silent and I'm quite disappointed in the lack of quality.

I have a Fluval Flex and have used the 2.0 and 1.5 as a replacement pump for the Fluval pump that came with the tank (the 1.5 is smaller in vertical length to reach the bottom back tank chamber where the 2.0 fits perfect with the pump tubing that came with the tank, however, you can make either work!). The pump flow and suction power is amazing in comparison to the Fluval standard pump. Maybe it’s because of my tank but I have but I also have a Fluval canister running and I can barely hear anything. In addition, I run a hyggar wave maker. I have zero heat issues anymore. Maybe I have some extra barrier with this tank but this pump made a difference with the flow output dramatically. I love Fluval and all their products (I just think the pump that comes with their tanks isn’t their standard quality but more a generic, run of the mill pump which they expect you to upgrade anyways I’m sure). No complaints here! (Side note that I rotate these pumps because I don’t have time in one instant to clean it and put it back in so, I rotate them based on which one I have clean at the time, they run like a champ and no broken ones yet! Also, Fluval did not make a pump compatible size wise for my tank).

Great pump. Dead silent? No, but incredibly quiet in my setup. Lots of power for small package. Nice long power cord to easily stretch to your available power source. Liked so much I ordered a Nano two days later to get a water feature going again. Great buy and will be back for more as needed. Only complaint is Amazon insists on throwing these in a padded envelope that does not provide adequate protection. Factory packaging looks like it has been thru a war, but pump was unscathed to my very good fortune.
