SICCE Syncra SDC 6.0 Water Pump 530-1450 gph WIFI Apex Controllable Aquarium DC Return with Controller | Quiet, Submersible or External | Fish Tank, Sump, Pond, Freshwater and Saltwater Marine Use

The pump has wifi capability that can be controlled from anywhere in the world. Also sends and monitors the temperature of the water with notifications sent directly to your cell or email or both!! The pump is very quiet and setting up wifi was easy. As it required 3G band I suggest you turn off the 5G while initially setting it up. Once connected and tested turn on the 5G. This worked great for me as I noticed in the comments that some people were having connectivity issues.

Works great. I have it in a 40g sump on a 60g freshwater aquarium at 50% power. It's working fantastically. The pump is silent and the ContrAll app is very convenient. One thing to remember - the pause function only pauses for a short time before self starting again.

Sorry if I come off as a bit of a Sicce fan boy but they’ve delivered another great product. This pump is quiet, powerful and completely controllable. Best of all it’s built on a proven platform with readily available replacement parts. Every Reefer knows that our tanks take their toll on our gear. Even with maintenance and a quality product, parts will wear. Take a look at the parts store, you can basically rebuild it. Plus, the warranty is stellar!Speaking of parts, everything you need to hook up to your plumbing is in the box(looking at you Ecotech). I’m a fan of the app and it’ll work with Apex should you go that route. If not, the included controller is pretty slick! It also has presets to be used in a closed loop. I really am loving this pump!

I purchased the Syncra SDC 9.0 recently and had a few issues, I opened a ticket almost a month ago with Sicce support, still no answers after several attempts.The pump is decent, a bit louder than the one it was replacing.Moves a nice volume of waterPeriodically/randomly changes speeds even though it's set for constant speedHad it not been for the noise and the random speeds, it would be a 5 star pump. Ironically, I opened a ticket about the random speeds but no response from SicceIf they fix the problem, I will update the review to reflect it

I have this in a 40 gallon sump for a 125-gallon main display tank. I only run it at 57% power. I have two ¾" returns and at 100% it will suck the sump dry so I just powered it down and used the ball valve on the main drain to regulate the amont of flow to prevent the overflow from making the sucking sound. Works great and the wifi feature is very handy. The temperature is also very accurate and I use it instead of the other thermometers in the tank and sump to monitor the temp.My only complaint is that is slightly noisy for DC style pump. I would not say it's loud but you can definitely hear a low hum coming from it. This isn't bad at all at 57% though. If I ran it at 100%, then I would most likely have returned it.

The pump works but the alerts and temp display do not. I emailed customer service who prompted me to unplug and plug it back in again. Did not work and they will not return subsequent emails. The app is basically useless. Might have to return it but without a backup pump this is a huge problem.

This syncra sdc 7.0 pump is more powerful and much quieter than my old Deep Blue pump. It’s probably overkill for my 125 gallon system, but more flow equals happy corals and fish. I like that it came with enough fittings to run submerged or inline. Easy Wi-Fi setup and controls make this return pump easy to use. The app is very user friendly as well. I’ve had a small sicce pump for my protein skimmer for 7 years so I know their pumps are built to last. I’m so glad I purchased this product!

Very silent and efficient. The app works greatly. Love it.

Beautiful pump but sadly it doesn't come close to it's rated flow. Maybe as a stream pump it might come close but not as a return pump.
