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.

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

Product Questions
I’m new to all this and I got a 175g aquarium secondhand. I’m setting up my first saltwater tank. The previous owner used this pump and it came with the setup. Is this pump sufficient enough for a 175g tank with a 39g sump?
Question by: Jerry Hayden on Apr 1, 2025, 11:47 AM
For that size of a tank I would recommend more the Sicce SDC 9.0.
Answer by: JJ K (BRS Staff) on Apr 6, 2025, 3:22 PM
I am looking for a fully reliable return pump that easily restarts after power outages. I currently have a danner which seems to get stuck even though I clean it regularly and often not restarting until I reset the impeller and sits there overheating trying to restart. . I read reviews on Sicce and wondering about one that says impeller problems on both his 3.0 and 5.0 after a year. I will need a 5.0 since I have a 125 gallon. Is this pump fully reliable? Thanks
Question by: Charlene Donnelly on Jan 10, 2023, 9:22 PM
Hey there,
Thank you for reaching out to us. From our experiance Sicce pumps are very realiably. As long as you keep it clean, it should have no problem restarting. Varios pumps are also great.
Please let me know if you need anything further and take care!

I can see the highest Flow rate. What is the lowest i can turn down? I am planning to use it for UV.
Question by: Lana on Nov 7, 2022, 12:33 AM
Thanks for reaching out to us! There is no exact flow rate setting, it is a manual dial that does dial it back but there minimal flow rate isn't a percentage like you would see on a DC controllable pump. We'd recommend setting it up and doing the bucket test to dial it in as closely as possilble to the desired flow rate. Let us know if we can help with anything else!

Is this pump good for a 90gallon reef tank?
Question by: Michael Purcell on Jan 31, 2022, 7:45 AM
This would be a great pump for a 90-gallon as long as your head pressure is not above the recommended guideline.
Answer by: Matt Lucero (BRS Staff) on Feb 2, 2022, 1:16 PM
If I have a 240 gallon Tank and a 40 Gallon Sump. With displacement I calculate to be around 245 gallons of water total. How would I get a pump to create 10x turn over without the water screaming through the sump? Don't you want the water to be a slower flow through the sump?
Question by: Daniel on Nov 27, 2017, 2:20 PM
Ultimately you will want your sump to be able to handle the flow that is being circulated through your display tank. If your sump is creating bubbles and splashing then the sump size should be increased or redesigned. Now, when you start talking about return rate with larger tanks, the 10x return rate becomes a loose suggestion since that is a ton of water flowing. Most people will decrease down to about 5x the display size for the return flow rate and then supplement with powerheads or a closed loop system.
Answer by: Charlie on Nov 27, 2017, 2:43 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?
Thanks!

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. :-)

Hello,
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
Any inside on this, it looks like it is not easy to find these..
Thank you
Henri

Question by: Anthony Griffin on Jul 11, 2016, 12:56 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.
Answer by: Charlie on Jul 11, 2016, 1:41 PM
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!

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

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?

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!

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 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 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 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!

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 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!
