Reef Octopus VarioS DC pumps give you enhanced performance and precise control of flow through your aquarium's reactors, sump, or closed-loop system.

The safe and energy efficient VarioS DC pump now include the new VarioS controller giving you more control. With 5 different energy saving speeds and two feed modes, the controller lets you know what your pump is doing at a glance.
Third Party Control
There is a dedicated port on the VarioS controller letting you directly connect your VarioS pump to any third party controller through a 0-10V reference port. Controlling your pump through a controller like an Apex lets you create your own flow profiles which are particularly handy for closed loop systems creating a random flow throughout the aquarium.
Having a pump that lets you directly attach a float switch has several advantages. The float can let you set high or low points in your sump, skimmer cup, or display tank that will shut the pump off when the float is activated.
The VarioS controller includes a waterproof 3-conductor union that connects to the pump creating a safe and detachable connection.

My 5 Year Old VarioS 4 still Running Strong By Matt on 6/30/2020Matt would recommend this product to a friendMy VarioS 4 Turns 5 years old soon and it's still running like it did on day one. I have used other pumps that have not lasted a year. VarioS will always be my goto going forward on any replacements and future builds.
Great pump, Not so great controller By suyong on 4/25/2020suyong would recommend this product to a friendLong term review: I bought the pump in 2017 from BRS. Within the first year I lost the #5 led and attempted to email REEF OCTOPUS directly and was just ignored. This month I noticed I lost my #4 led and was told by a friend to contact coralvue. long story short they said it was out of warranty and just sent me a link to purchase a new controller. This is a super silent pump and to the looks of things the flow wasn't affected
Power supply By Scott on 12/5/2019Scott wouldn't recommend this product to a friendIt's my return pump on a refer 350 I've had it 3 months and the power supply is not working
Quiet By mark on 6/25/2019mark would recommend this product to a friendMy first DC pump. So quiet. Love the feed function.Using on a 120, perfect fit.
Great pump! By flgbanjo on 8/6/2018flgbanjo would recommend this product to a friendBuilding out a 66 gallon reef and decided on the Varios 4 due to positive reviews, a good flow rate and being able to tie it into my Apex. Very quiet pump and so far very happy with my purchase.
VARIOS pumps are Solid!! By FLSharkvictim on 3/17/2018FLSharkvictim would recommend this product to a friendI have ran a few of these VARIOS pumps! I have the Reef Octo REGAL Protein Skimmer and it's runs the VARIOS-2. Wow, I thought the new SKIMZ Quite pro pumps were good these blow them away. They run nice and quite and are build like a tank! I bought this one for a my saltwater mixing station that is connected to my main display. I have been through 3 EcoTech M1 pumps in the last year and a half. Whats crazy, is I clean all of my pumps in 2 part, 1prt Vinegar and 1 part RO water, so I take care of my pumps. I might even go with a VARIOS-8 for my new SCA 150 BUILD & have my Ecotech M1 for a back up on stand by!! My saltwater mixing station is two 25 gallon NSF Storage Barrels and I will be adding this pump to mix my salt and transfer water over to the saltwater barrel..
Buy it! By Ferrell on 11/20/2017Ferrell would recommend this product to a friendI can’t say enough except I wish I would have bought 2. Lol. They work flawlessly and the float switch and 0-10v is a bonus. I’ve only been running it a month in the tank but used it to move water while filling the tank. Spot on every time.
Great pump By David on 9/12/2017David would recommend this product to a friendI have had this pump running on my 125 now over a year and still running strong. So quiet you can't even hear it running. Also no vibration in the plumbing. I highly recommend.
Quiet & easy to control By Elliot on 6/5/2017Elliot would recommend this product to a friendSo far no complaints; completely silent and comes with a variety of fittings for outputs. The controller is also well designed and easy to use, and I like the fact that it comes with a float switch. Do note that the float switch must be installed upside-down if you want to use it in the sump (corded side of detector facing down).
Super quiet By Marquise on 2/17/2017Marquise would recommend this product to a friendThe pump is installed on the sump of my 93g cube and its SUPER QUIET!!! The controller is easy to learn and the float switch is a bonus
Dead silent... By Dan on 11/29/2016Dan would recommend this product to a friendIt is so quiet, I thought it wasn't working right until water came rushing out the return line. Pumps a bit harder than a mag 7. We'll see how long she lasts.

Make sure to let us know if you have any other questions.
Can this pump be used as a return pump on a 65 gallon sps reef? Can it be set up with a battery back up and if so, what all would be needed to do such?
Is the flow output continuously variable using the 0-10v interface, or is it limited to the same 5 levels available with the VarioS controller?
Do you have the skimmer version of this pump - Reef Octopus VarioS-4S Pinwheel Pump ?
On the flow rate/ water head picture above. What setting 1-5 is used to make these readings?
The flow chart on this page is based on the maximum flow setting for this pump. As head height increases and gets closer to the max head rating (14.7ft), the flow will continue to drop and eventually reach zero.
