CURRENT USA eFlux DC Flow Pump with Control 1050 GPH | Loop Controllable Aquarium DC Return 210-1050 GPH | Quiet, Submersible or External | Fish Tank, Sump, Pond, Freshwater and Saltwater Marine Use

Update. I replaced the 1/2 ID tubing with 1.25 ID tubing and the pump is now flowing like Niagara Falls. It doesn’t like 1/2” tubing. Put too much head pressure on it. It’s lasted about 3 years now without fail. I bumped it up to 4 stars instead of 5 because it would be nice to have a digital readout or notches of somekind to tell you what the flow rate (doesn’t have to consider head pressure) is.For the money this pump is really low powered. A much cheaper Quite One pump has a much higher actual flow rate. This thing barely trickles. The controller knob is pointless with such a low flow rate. This is supposed to be 1900 GPH but I seriously doubt it. I am running it on a 100 gal reef tank with a 20 gallon sump and an actual 1900 GPH flow rate would be plenty. It also does not detect when the water level is too low and turn itself off. In this price range, it should do so. On the positive side it has been reliable. Though I have cleaned it several times in hopes of getting better flow it really does not need it. On a 40 - 55 gallon tank this might be a decent pump, but for this price you can do much better. it also does not work with universal DC battery backups as Current decided to use a different shaped plug than the other DC pumps. That backup would have come in real handy during the recent freeze in Houston. I plan to replace it as soon as I can. It is a shame I wasted $170 on it.

I bought this pump because I upgraded my lights to Current LEDS with the Bluetooth Loop system. I liked the fact that I control this pump with the Bluetooth controller. The pump came with all necessary 3/4 and 1 inch pumping, controller, power supply, mounting hardware and instructions. I run 3/4 inch in sump return line. So I attached the screen to intake and put the 3/4 inch hose barb on. I used a zip tie to secure the hose to the barb for extra safety. I then I mounted controller and set up with loop. I plugged in the power supply which by the way is same supply that is used for LED lights. I went into loop app and adjusted the power of the pump. The pump runs at 30 percent at lowest setting. It will not go any lower. After a few minutes of playing with volume I settled at 60 percent. I have a 55 gallon standard tank with a corner over flow. And in the pump settings I have the feed section on. The pump powers down to 30 percent for 10 mins for feeding mode. Then ramps back up. The pump is very quiet and powerful. Some things when setting up. First Current uses micro USB for the pump controller to Loop controller. The cord isn't that long. So plan accordingly. Next you have to plug the micro USB on the pump controller in the way instructions say. If not Loop will not control. Its the farthest right on the controller. The last thing is that this does not come with extra extension for pump power. I got lucky and didn't use the ones from my lights. So I used the one. The nice thing about this setup is the extensions are all universal. So they work on lights or pumps. About flow. You could get away with this pump probably up to a 75 gallon tank. But the same works perfectly for a 55 gallon. The last thing is customer service with Current. I had a few questions on setup. I called first thing when they opened. And got an answering machine. Left a message. I think they called back but I figured it out myself. I didn't try the email support so have no idea. Besides the customer support issue I would recommend Current products. I will update if I have any issues with this pump.

I’m using this eFlux 1900 to power an FX6 + CO2 reactor + UV sterilizer + heater. The pump itself is great. It does what it is designed to do: move a lot of water. Compared to my FX6’s internal pump, which does around 400gph with the other equipment attached, I’d estimate that it does 600-700gph at full speed and at 5’ head. Maybe even more. The only flaw is the fit and finish of the pump itself, and the controller, which is average at best.

Have this running inline for a aquarium chiller and it’s literally silent. I sometimes can’t even tell if it’s on cause even if you touch it there’s no vibration or noise change. Definitely the best pump I’ve ever owned. The controller is nice and I like how it comes with a removable mounting base. Only gripe is if you want any kind of Wi-Fi control then you have to buy their extra Wi-Fi hub to get that working but for my application it really isn’t needed.

I use this for the return pump from the sump of my 65 gallon salt water tank. I really like being able to adjust the water flow and it is quiet. Been running for a few months now, so far so good 👍

This replaced my 14 year old Iwaki MD40 (Japanese motor) and another off brand pump that was feeding my reactor and skimmer.1. This pump is QUIET! The Iwaki sounded like it belonged in a diesel freight train even from day 1. This pump has just a slight hum and once the water is moving through the overflows and sump you don't even hear it.2. I have the IC Marine light bar and wave pumps so I added this to the network for feed mode. In feed mode it reduces to 30% flow and the wavemakers stop so that the fish and coral can eat. The 30% is supposed to keep backflow from happening but I like it because it's enough to keep the food suspended and off the sand and rocks but it's not enough to make the fish work for it.3. Power consumption has peaked out at 88 watts compared to the 140 from the Iwaki and 80 from the other pump. I monitor my pump consumption with Smartthings power plugs with metering built in. I have alerts setup that zero power consumption in 15 minutes triggers a text and app alert.4. Flow is very good, I've plumbed this in to my returns and teed off to feed the skimmer and reactor as well. I had 6 returns and I turned two off since I'm also running the wavemakers that more than make up for the shutdown return lines at the sand level. The skimmer, an EV-180 puts out wet foam and the reactor has good flow for the carbon and whatever else I throw in there.5. Two bad things and they're just minor is the barbed fittings are 1.5" and 1" so I needed to adapt my 1" feed up to 1.5 and the power cord was too short to reach my hub nest in the canopy. I had to buy an extension cord from Current to reach. If the cord was long like the power heads it would be better.
