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.

Great, Silent Return Pump By Jamespias on 11/11/2019Jamespias would recommend this product to a friendI've been running this on a 120G tank for two years now. Pump has worked flawlessly and silently with no maintenance. I start and stop it multiple times per day for feeding, cleaning, or whatever and it always starts right back up. It is literally the quietest thing running on my tank. Also, I am only needing to run it at setting 3. Pump is located in stand under tank and has to pump about 5ft vertical with 3 90degree elbows and one step down in PVC size. If I run it any higher, it'll overflow the display unless I modify the overflow weir to handle more flow. Even so, I'm getting more than enough turnover in my sump and wouldn't want it any higher.
I did have a time when the pump was new where it would "mysteriously" start and stop constantly and I thought the pump was broken. It turns out that it was because of the way that I had the float switch set up and it was my fault! The pump was doing what it should have, and I had it set up wrong. Makes me wonder how many other people here have this issue when they are talking about this pump being unreliable.
i do not think i would recommend them this pump By peter on 6/1/2019peter wouldn't recommend this product to a friendi have 1 VarioS-6 and 2 VarioS-8 they are all 9 mth old . one VarioS-8 stopped working in the first 15 mm , the second one had to repair 2 times and now my VarioS-6 is down CoralVue Support is ok but pumps allways seem to be down for at least a week by the time you get the parts but sometimes it can be 3 or 4 days before you can get a hold of them , for the price i dont feel they are worth it you can buy more relabel dc pumps for less money
Good pump...when it works By Robert on 4/20/2019Robert wouldn't recommend this product to a friendI bought this pump with my 750XXL about 8 months ago. The pump worked great for about 6 months. The pump seized up, requiring a trip to an aquarium store to buy an interim replacement. Bulk Reef directed me to Coralvue for service. Customer service was fine. I sent the pump to them as requested,(shipping was paid by me), and they sent it back with a new impeller. That lasted about 1 month before it seized up again. I'm back to using my back up pump, waiting for resolution to my problem. I, so far, have no complaints about customer service from Coralvue or Bulk Reef. However, the quality and dependability of this pump is questionable.
Both malfunction By Ryan on 1/29/2019Ryan wouldn't recommend this product to a friendI got two of these to use as return pumps. They both start and stop sporadically. They have only been used for two days also. One more than the other but I can’t even use one since it does it every 2 mins. Tank is limping on one pump right now.
Various 6 By Ralph on 12/19/2018Ralph would recommend this product to a friendExcellent dead silent pump , love the controllability, I’ve got it set on eco mode on a 90 gal and it moves approximately 300 gph in a trigger sump , love the fact that brs only sells quality reefing equipment
GREAT PRODUCT By PETRO on 11/23/2018PETRO would recommend this product to a friendEXCELLENT PUMP . MOR THE HAPPY WITH IT!!!
Excellent Pump By Dennis on 10/10/2018Dennis would recommend this product to a friendI have been running this pump for 1 year and some months. This pump runs great. I do not see how this pump (Varios 6) received any bad reviews as it runs great. I have not had any issues with this pump and I plan on purchasing the varios 8 when I upgrade my 150g to a 300g. Reef Octopus makes great gear and now we can add the pump to the list of outstanding gear.
excellent By RT on 7/12/2018RT would recommend this product to a friendI have had this pump running for about 2 years. It is not quiet, it is silent. The only noise I can detect is a low low water turbulence going through the soft plumbed return line. The pump itself hasn't had any problems and hasn't been cleaned once. The controller did malfunction as the LED lights stopped working. I had to buy a new controller from the manufacturer at about $70. I have a skimmer with the same pump and it has the same track record although the controller has been fine. Most likely I will buy this again in the larger version when I upgrade.
Just not much flow By Stephen on 7/3/2018Stephen wouldn't recommend this product to a friendI purchased the varios 4 and varios 6 thinking I would have good pumps. The reviews seemed good enough. But, once these pumps were installed, The flow is no where near what they are rated for. The varios 6 has a max head height of 16 ft. I have 2 90 degree elbows and a total of maybe 5' head height. I am only getting around 250 GPH with this pump. Somehow the flow has been fractioned with just that little bit of head height. There was no noticeable difference even when it was only about 4 ft head h eight. I still maintained approx 250 GPH. Very disappointed with the performance. I would have maybe expected half of the flow loss, but I did not expect to only get about 15% of the performance it is rated for.
So far so good By GoldenReef on 5/16/2018GoldenReef would recommend this product to a friendSo far so good its only been running just a few weeks so I am crossing my fingers . Quite operation . Lets hope it stays solid!
Does not live up to the hype... By James on 4/27/2018James wouldn't recommend this product to a friendSo I have a few tanks and this is the loudest DC return pump I have. I bought because it was to be the quietest and feel let down. Not as loud as a mag but pretty close.
Cons: Loud, only 5 speed settings, no flow specs on each speed setting. 10V port is nice but worthless with a herbie overflow unless you want to overfill your tank or sump. On start up more flow, let it run over night and you have less flow
Pros: quiet enough to get by, great for a back up, Float turn off during water changes is a HUGE plus, on off button on controller
Summary: If you want to use this as a main pump I would think twice. I personally would not recommend or buy again.
Quality Pump By MplsP on 2/24/2018MplsP would recommend this product to a friendStrong, efficient, quiet and reliable. Not much more you can say. In terms of noise, when running full blast, the pump has a very soft noise, something higher than a hum but lower than a whine. When I close the door to my sump, it's inaudible. In any case, it's softer than my IceCap K2 skimmer.
Would the ecotech battery backup system work for this pump? If not, which system would?
How do these pumps do in terms of noise produced? And are these "Apex Ready", or "compatible with an Apex"?
The VarioS pumps are “Apex Ready” pumps and are very quiet just like all other DC pumps. On full blast you may hear the slightest bit of noise but if you turn the power down just one step they will become virtually silent.
What cord would be needed to connect this pump to an apex controller?
I'm setting up a 120 with 40 gallon sump. What would be a good reliable pump for this system?
I have a Red Sea Reefer 250. Would this return pump be over kill for a reefer 250 with a few media reactors and UV sterilizer added to the return line?
Thanks for getting in touch with us in regards to this pump. This would work perfect for what you are trying to do there. This would also allow you to not have to run the pump on its highest setting which would put less stress on the pump throughout its life. Please let me know if there is anything else that we can assist with. Thanks!
Can this be controlled with the reefkeeper and the APC mod, or even with the feed mode on the reefkeeper? Or will i need to use the pumps controller?
Does this pump come with a 1" barb output fitting? Some sites say it has a 1.25" barb and another says a step down barb adapter similar to a hosetail. Your site doesn't even mention the barb fitting. I'm referring to the Varios-6 return pump specifically. Thanks...
Output: 32mm/1.25" (barb/pvc coupling)
How are these DC pumps on heat transfer? I have used Mag pumps for years but the heat generation requires an external install. Do these run cool enough to sit in the sump without over heating the tank?
