Quick Overview

Why does BRS recommend this?

The Syncra Silent line of pumps come in many different sizes and will fit most tank needs.  Sicce uses high quality magnets in their pumps, which allows them to spin smoother with less noise than almost all other pumps in their price category.  If your tank needs a high flow return pump, or a smaller pump for a low flow reactor our first choice will always be Sicce.

Quiet, energy-efficient pump for a variety of uses in wet or dry application. Use in salt or freshwater.

  • Strong Quiet Pump By RobertP on 5/17/2017

    Guess it depends on your definition of silent! I plugged it in and thought it was dead because I could not hear it. I had to get up and look at my outlets to see that they were in fact pushing water! Now I do have the rubber feet installed and I have it sitting on top of a thin piece of rubber and keep it from touching the sides of my sump. No buzzing or anything. I have it shutting off twice daily for feedings and it just runs like a top! My apex says it is only using 57Watts which is about half of what it is rated for....almost half of what my mag 9.5 is using on my skimmer.
  • Solid, But Not Silent By Dan on 11/11/2016

    I have this unit on my return with it running at full capacity. It gives off a decent amount of noise and vibration. When it is turned down to the minimum level there is a big difference in noise and vibration in a good way. It does the job and has been running great for almost six months with no issue.
  • Nice design By Ken on 4/5/2016

    Purchased for a new build based on BRS recommendation. Only four stars because it is not installed yet but out of the box it appears to be built well with maintenance in mind.
  • Dead Quiet, Powerful By Angelo on 1/15/2016

    Silent and extremely powerful. Easy to clean. Suction feet come off easily but not an issue. One of those purchases that leave you feeling satisfied. Recommended, purchased a second one for back up. Can't wrong
  • Loud By DG714 on 12/22/2015

    Bought it thinking it would be quiet but my old dc pump is much quieter. I'm going to switch it back and sale this one on CL.
  • WOULD BUY AGAIN By ALAN on 12/16/2015

    This pump works great on my 80 gallon as the return pump. I love the adjustable flow rate.
  • Great pump but NOT silent By Vincent on 3/30/2015

    Silent to me means, can't be heard. In my EShops R100 Sump vibrations do create some noise. So for false advertisements I give it 3 stars. Further more they have since come out with the Pro Line (that will not fit in my sump) that is advertised as quieter than this.... How can you release a pump quieter than silent? I still recommend the pump, but is it Quiet, not silent!
  • Silent By John on 3/27/2015

    Powerful pump and very quiet. I put it on some food safe silicone mat and made it even more silent. Great product!
  • Very quiet and adjustable By Michael on 3/4/2015

    I've had this running for 6 months now and it works great and is totally silent as the name suggests. It is also adjustable.
  • sicce syncra silent 5.0 pump By david e on 2/24/2015

    this pump is fantastic! I expected it to be louder than the sicce 3.0 it replaced but it is just as quiet. very powerful also if I put it in the kitchen sink I could open the window and clean my neighbors aluminum siding! great product!nytastn
  • Solid Pump By Cliff on 12/1/2014

    I originally had a DC10500 pump in my Sump, but it died in less than 3 months! I luckily had this pump available because I was using it for water changes. Well let's just say that this pump can perform as or better than advertised! My sump is in the basement and my reef tank is on 1st floor , so roughly 8 ft of head, plus a check valve and ball valve shutoff. No worries, it just keeps trucking! Silent is in the name for a reason, very little noise.
  • Great Pump By Nick on 11/23/2013

    I was recommended this pump from a BRS phone rep, he spoke highly of it and it was on sale. The pump lives up to all expectations! It is dead silent and has great flow! It also does not seem to put off much - if any real heat!

Product Questions

I'm building a 110g vs a 90g reef with 35g sump. Head ht would be about 60in vs 54in depending on which size I go with. Would this pump be sufficient?
Question by: Dustin on Apr 24, 2016 12:40:00 PM
Great question!
We have personally used the Sicce 5.0 on a 110 gallon with great success! Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Apr 27, 2016 12:07:00 PM
I'm building an AIO compartment for my 45 gallon. It will be 11" x 5" x 12-16" (L x D x H). I calculate ill have 21" of linear flow into the box, which could handle approximately 1400 gph. Would this pump work for this?
Question by: Joseph on Mar 29, 2016 8:10:00 AM
Great question!
This pump would be slightly overkill for a 45 gallon tank. Typically for return pumps they are based on 10x your system volume so a pump around 450 GPH would work great without too much flow. Even while you have the option to run up to 1400 GPH you will not need to as it will only fill up as much as the return pump can push back into the display. Feel free to let us know if you have any further questions!

I did use the Syncra 5.0 and 3.0 but after 12 months each time one of the shaft bloc the implelled ... Now I am looking where I can purchase implelled replacement parts

Great question! Unfortunately we do not carry the replacement parts for these pumps. We recommend reaching out to the manufacturer directly for parts vendor recommendations. :-)

I have 1" pvc tubing coming out of my sump. Do you have what I would need to connect the outlet from this pump to that 1" pvc. The pump outlet is so much smaller than the pipe going out to the tank I cannot figure out what I need in order to connect the two. Thanks!
Question by: Andrew Bruemmer on Apr 27, 2016 11:20:00 AM
Great question!
We recommend attaching 3/4" silicon tubing to the pumps barb output. (link below)
From there you will need the Reducing barb fitting which is 1" threaded on one side and 3/4" barb on the other (link below)
Finally you can thread the barb adapter onto the female pipe adapter (listed below) and glue the female pipe adapter to the 1" PVC

Would this pump work in the Red Sea Reefer XL 525? The recommended flow is 1060 gph. Can this be dialed down slightly or ok for output to be 1321 gph?
Question by: Robin on Feb 24, 2016 12:39:00 PM
Great question!
The Sicce 5.0 would work perfect! Overall it would not need to be dialed down too much as the head pressure from returning the water to the top of the tank would account for the extra 300 GPH. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 24, 2016 2:45:00 PM
I am building a 120 gallon reef and have about 12' of head as the sump is in my basement and the tank is on the main level. With a few 90 degree bends up to the tank what do you recommend for a pump?
Question by: Jason on Mar 9, 2016 10:58:00 PM
Great question!
For a submersible pump the options are limited with a 12' head height down to our DC options. You can get by with the Vectra L1 by Ecotech and tubing down the flow as well as the Waveline 12000 as a great alternative. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 10, 2016 3:47:00 PM
Hi there,
Looking to plumb somewhat of a manifold off my return pump that will feed 1. My 60 gallon display (about 4.5 ft head pressure), 2. A 40 gallon remote refugium with overflow draining back into the sump (around 4 ft of head), 3. A BRS dual reactor. All feeds will have a gate valve to fine tune flow.
Is this pump a good match for my needs? Also, I haven't been able to find anywhere, but I see that the pump flow rate is adjustable, any idea what the low end of flow is for this pump?
Question by: Mark on Dec 10, 2016 7:03:00 PM
Great question! This pump will be perfect for your application and manifold! Unfortunately, we do not have the flow ratings for this pump when adjusted to the lowest setting. :-)

I'm setting up 200g deep dimension tank
Will this sufficient to properly recirculate the tank using a trigger system 39 sump.
Question by: Anthony Griffin on Jul 11, 2016 12:56:00 PM
Hi Anthony,
Normally we will suggest anywhere between 5-10x the display tank volume for a flow rate through the sump and then up to the display. The head height of the tank above the water level in the sump will also become a variable in how much flow will actually make it up to the display tank. The Sicce 5.0 would get you on the very low end of the flow suggestion that we have. You may want to take a look at the Waveline DC10000II since it does have much more available flow, and being a DC pump you can fine tune it to the flow your tank and sump will handle.
