SICCE Syncra Silent 0.5 Multifunction 185 GPH Submersible Water Pump | Italian Made 8W Ultra Quiet Durable for Aquarium Fish Tank, Fountain, Pond, Hydroponics, Terrarium Black | Freshwater & Saltwater

I have an IM Nuvo 20 and both the stock pumps got zapped when the outlets were dunked in water by mistake. I bought these after trying cheaper Chinese ones on Amazon and returning those. These are worth the premium. They run silent and have self-cleaning impellers, plus they are eco-friendly so they run efficiently for cheaper electrical costs. These fit great in the center compartment in the back, with enough space in between to put a 50-gallon rated stick heater.The 5-year warranty once you register is proof of the confidence behind the product. Pay the extra little bit for this instead of cheaper Chinese ones online and you won’t have to think about your pumps for years to come.

The pump is quiet! Just have to insert it into a fluval evo with the chord side facing the outermost glass panel of the rear filter chamber. (Right side of tank when facing it). But my experience is that’s it’s quiet I have a tank with zoas, GSP, a few leathers along with rock flower and bubble tip nems and so far it’s doing good. It doesn’t quite break surface tension. I have it on full power and I wish it had just a bit more power to manage flow over the whole tank. It pulls water very well through the refugium i have then the immense amount of bio filter I have.Solid pump there are certain reliable brands for pumps, heaters, lights; and Sicce is one of the best and most reliable pump brands, that comes with a 5 year warranty. Money well spent for sure.

At first I saw the pump and I said this pump is way too little it's not going to work but after I plugged it up and submerged it into the pool that sucker was really pumping water it is really nice and works real hard

I have used a lot of small pumps for various projects over the years. I have an indoor fountain that needed a complete rebuild (25 old years with only minor repairs) and I always was a bit disappointed because the miniature pump I had been using (you know the one!) was loud enough to hear on the entire first floor of our 2 story home. I took a chance on this one because it advertised 'silent' not 'quiet' and it is made in Italy (I am Italian too). Well, the claim is absolutely true. It is possible to hear the pump if you are less than 12" away from it, otherwise it is truly SILENT. You will need to have bit of patience as others have noted as the pump needs a few hours to 'break in' to silent. Don't send it back until you've run it at least 3 hours. Hope this helps!!

Works really well and is very quiet but I have about a 8-10” head height and it really isn’t as strong as I would like from the GPH rating. Would of gone to the 1.0 if I could do it again.

Looks like a decent pump. Wouldn’t have bought it if it were properly labeled though. I have a 0.75 inch tube I want to connect to. The picture showed that it comes with two sizes of adapter one for smaller and one for bigger tubing. This was inaccurate, it came with two identical adapters. Both the small one shown.

I accidentally purchased this pump thinking it would fit in the "return" chamber of the eShopps Deskmate 4.8. I wanted the additional flow, so I made it work!Extremely happy with the additional slow in my tank, and the pump lives up to its name...it is SILENT!

Incessant rattling. Incessant humming. Incessant vibration. Whoever says that this pump is silent either doesn't have to live with this pump or they actually got a silent pump but it was sheer luck of the draw that they did. After spending some time swapping impeller assembly parts with a Tunze pump (also made by Sicce, and therefore identical (and therefore also loud)), I got it to quiet down a little. I replaced the impeller (but not the shaft) and then removed the loosely fitting (and super rattlely) back and front covers. But even after these modifications, it was fairly loud just not as loud as before.So why did I go from one Sicce-made pump to another? Because there isn't much of an alternative. There is the NEWA Mini, which was much quieter than the Sicce, but still annoyingly audible, and the Eheim Compacton, but I read bad stuff about that one. There are also countless cheap pumps from China, but I don't trust those, not because they're from China, but because they are super cheap.So why three stars and not less? Because this pump works. It does the job competently. It moves water. It excels at that. If you don't mind the noise, than this pump might work for you.
