Sicce Syncra 1.0 Aquarium Pump, 251gph

This pump was recommended by multiple people to use on my daughters Fluval Evo 13.5 tank. It moves a lot more water than the stock pump and is ultra quiet. I can't even tell it's on without looking for the water flow. The Fluval Evo's third chamber is a tight fit but with a little moving around, we get no noise out of it.

Personally I am very allergic to noise. My used aquarium came with a very noise pump. Had to replace it, and choose this one. Initially, it still made a bit of noise. I guess because there was still some air inside it, or vibrating a bit against the walls of my sump. It's nice and very silent now. Quality build too. Very happy with it.

It’s been a year and this pump is still going strong after running almost 24/7 (turn off for feeding tank).It isn’t perfectly silent, but I like it enough I have since got 2 more. One for water changes and another for another tank I am in the process of setting up.

I received my pump earlier today and here is what I like so far.1. Moves A lot of water compared to the stock pump that came with the Fluval 13.5 as of right now there is a slight dead spot in the tank which is underneath the return nozzles. But very minimal dead spot.2. No modifications the stock return hose that came with the fluval is a bit longer due to the minimal height of this pump so there is a bit of slack. I did not cut it off just in case this pump failed for whatever reason and I had to switch back to the stock fluval pump.3. The noise level is minimal. There is a slight hum... from 3 feet away but you can barely hear it. You won’t loose sleep if it’s in your bedroom.One final comment. when I installed this pump it picked up a lot of uneaten food and other goodies you may find in your sand/gravel tank cleared up within 1 hour. Fish are swimming in the current and look happier.

This is my 3rd Sicce pump and the work great!! This is silent like it says.
