Quick Overview

Ideal for automating 2 Part dosing. Our peristaltic pump has an extremely accurate 1.1mL per minute flow rate. Silent operation. The pump utilizes a unique system that attaches the drive shaft at the bottom and top to eliminate shaft wobble. Precision two roller design extends pump life and will not back siphon.


Each pump is capable of dosing a single solution. You will need two pumps to automate both calcium and alkalinity solutions.

will your BRS two part doser include two pumps and be able to dose both parts from separate bottles for 74.99
Question by: ronald on Apr 11, 2014 9:33:00 PM
Hi Ronald,
No the pumps are sold per pump. To have two pumps to dose two liquids you would need to purchase a quantity of two pumps.
Answer by: Bulk Reef Supply on Apr 11, 2014 9:33:00 PM
How high will this pump pump and does the liquid need to be above the pump?
Question by: Scott on Jan 15, 2015 5:28:00 PM
Great Question Scott!
The BRS dosers will have a 20ft. max head height. The pump will be able to pull liquid up, so it will not need to be lower than the solution.

is the pump tube replaceable? if so do you sell the replacement tubes?
Question by: Chris on Nov 26, 2013 7:19:00 AM
Hi Chris,
It sure is. You can find the replacement tubes at the link below:

Answer by: Bulk Reef Supply on Nov 26, 2013 7:19:00 AM
I received my pumps today. I noticed in the package was two different types of hose. One was clear and softer than the other which was not clear and more rigid. Is one hose meant for input into the pump and the other for dispersing the fluid from the pump?
Thanks




Question by: Bruce on Jan 17, 2014 5:38:00 PM
Hi Bruce,
You can use either. The rigid tube doesn't bend as easy but holds its shape better, wheras the soft tube is easier to route around corners, etc but kinks a bit easier. Feel free to use either in whichever application is better suited.

What size of tubing fits on this doser? And does the input tubing different from the output tubing?
Question by: David on Dec 26, 2013 6:56:00 AM
Hi David,
Input/output tubing are the same and both are 1/4" though its a compression fitting so its fairly forgiving if your close.
Answer by: Bulk Reef Supply on Dec 26, 2013 6:56:00 AM
Can you order more tubing? I'd like to relocate my dosing pumps and need new tubing.

Thanks,
Kurt
Question by: Kurt on Feb 6, 2014 6:58:00 AM
Hey Kurt,
This stuff will do the trick just fine (most use clear).

What pump would you recommend to use? I have a 180 gallon aquaruim if that makes a difference
Thank!
Frank
Question by: Frank on Jul 15, 2014 12:42:00 PM
HI Frank,
It depends on what you are doing. Assuming you want to dose something like two part, this doser would be the best route to go because of the relatively small quantities being dosed.
Answer by: Bulk Reef Supply on Jul 15, 2014 12:42:00 PM
I dont no anything about dosing, How do you know how much to dose? What to dose? How do you program it? Any other tips?
Question by: Brad on Apr 22, 2014 9:20:00 AM
Hi Brad,
The pump itself doesn't have any programming. It just doses 1.1mL for every minute it is turned on. You adjust how much it doses by changing how long a timer turns it on. As for how much to dose, what were you planning to dose?
Answer by: Bulk Reef Supply on Apr 22, 2014 9:20:00 AM
What are the dimensions of this pump?

Thanks

Phillip
Question by: Phillip on Apr 27, 2014 9:27:00 AM
Hi Phillip,
It measures 4" x 3.5" x 4" Tall
Answer by: Bulk Reef Supply on Apr 27, 2014 9:27:00 AM
Hi,
I have the nano cube 28 with stand, and was wondering if I could place the 2 part solution in my stand, and have the pumps deliver the water into the sump area of the back of the nano cube. The water would need to be pushed about 48 inches up. Thanks!
Question by: Abe on May 6, 2014 4:37:00 AM
Hi Abe,
These pumps can pump up to 20ft of head pressure. Going up from the stand to the tank would be no problem at all!
Answer by: Bulk Reef Supply on May 6, 2014 4:37:00 AM
Do these have timers? How would you define when & how much to dose?
Question by: Navdeep on Aug 21, 2014 7:59:00 AM
Hi Navdeep,

These pumps do not include any sort of timer. They will need to be controlled with a digital timer capable of operating at 1 minute intervals (or less) or an aquarium controller like the ReefKeeper of Neptune Apex.

Here are the digital timers we carry.

I hope this helps!
Have a great day :)

What are the dimensions of the unit?
Question by: Joel on Aug 26, 2014 3:55:00 AM
Hi Joel,

The dimensions of our 1.1 ml/min and 50 ml/min dosing pumps are 3 1/4" W x 4" H x 4" D.
The mounting plate should allow for flush mounting on the wall so the depth measurement will remain the same.

I hope this helps!
Have a great day :)
Answer by: Bulk Reef Supply on Aug 26, 2014 3:55:00 AM
can the doser be mount below the end of the dosing line? I am planning to place me dosers under the tank and the outlets of the doser to the main display tank...which is above the doser level.
Question by: Alfred on Jun 15, 2014 3:19:00 PM
Hi Alfred,
That isn't a problem at all :-)
Answer by: Bulk Reef Supply on Jun 15, 2014 3:19:00 PM
I just got a dosing pump and was wondering if there was a maximum height that I can mount the pump in my stand. I currently have it mounted about a foot above my container of dosing solution.
Question by: Brian on Apr 4, 2014 8:32:00 PM
Hey Brian,
That won't be a problem. The pump shouldn't have any issue pulling solution up anywhere within a normal sized aquarium stand.
Answer by: Bulk Reef Supply on Apr 4, 2014 8:32:00 PM
Does the BRS 2 part doser draw enough power for the ReefKeeper PC4 module to reliably shut off when connected to channels 2 or 3 or should it be connected to channels 1 or 4?
Question by: John on Jan 27, 2014 7:24:00 AM
Hey John,
In most applications it is but I would still recommend using the relay outlets on 1 & 4 just to be safe!

BRS 2 Part Dosers are intermittent duty pumps and not meant for continuous operation. We recommend on/off cycles under a few hours to maximize life span. You will need two pumps in order to dose both calcium and alkalinity.  When used with controllers like the ReefKeeper or Apex, we recommend connecting these to a mechanical relay outlet, and not a TRIAC outlet on the controller's powerbar.

  • Great Pump By Brad on 6/1/2015

    I bought 2 pumps to dose my tank with calcium and alkalinity and they worked great. When I set them up and calibrated them, they were a little over 1.1 per min. so I had to re calculate but wasn't a big deal.
  • Great By Andrew on 5/12/2015

    These are great little pumps. Kind of a large footprint
  • Great Pump! By John on 5/6/2015

    Nice and simple pump for dosing. Very quiet and seems to be working well. Comes with tubing and calibration cup.
  • Great doser pump By Eric on 4/21/2015

    I bought two of these doser pumps for dosing 2 part solution. So far so good, 2 weeks in. One pump is a little faster than the other, so I left it on calcium since an overdose of calcium is less worrysome than an overdose of alkalinity.

    They're running on my Reefkeeper Lite. When using with a controller (which you should do as they should not run for long periods of time consistently) you should put them on mechanical relay switches instead of the solid state switches, as the solid state may not switch them off due to the low power draw of the pumps. Google Triac and your controller name to find out more.
  • Great product! By Steve k on 4/15/2015

    I ordered this doser for my Aquaripure vodka filter. I don't have to get someone to dose the filter twice a week while I'm gone. Makes my life much simpler.
  • Great pumps, watch the flow rate By Chad on 4/13/2015

    These pumps are working great so far and are a good value. However, I bought two for dosing and noticed they flow at different rates, one is much faster than the other so I have had to play around with the timing to get the dosing correct. One is right on at 1.1 ml per minute but the other is almost 2ml per minute.
  • Good ATO Pump By Glenn on 4/13/2015

    Use this on my 45 gallon for a ATO pump. Works great but was hard to prime and is a little loud.
  • Great quiet pumps, but need to be upgraded for use with Apex By Vincent on 3/30/2015

    The reviews here say it all. Great pumps! However if you are going to use this on an APEX you are limited to 2 ports (4/8). If you want to use it on the other ports you will want to get one of these or similar for each pump (Woods 4325C Single Outlet Power Adapter Plug) BRS I suggest you start selling these....
  • Highly recommended By cvicente on 3/30/2015

    Very impressed with the overall construction. Nothing best on this price range, I'm currently using the unit for Mg dosing. Would recommend it without hesitation
  • Great dose pump By David on 2/10/2015

    Ordered two and have not looked back as far as dosing. I use with the BRS additives and my corals could not be any happier!
  • Near perfection By Old Salt on 1/17/2015

    After years (literally) of dosing 2-part by hand, I bought two of these pumps during the Black Friday 2014 sale. Due to the tight space in my stand/sump area, installation took a bit of thought and time. But once up and running, they are, as my teenage daughter would say, "just sick." I control them with my Reefkeeper Lite's multi-timer function and the levels are always spot on. And now I don't have to train my neighbors in the fine art of dosing 2-part!
  • Great! By Jeff on 1/11/2015

    I bought 2 and have them controlled by my reefkeeper. Easily dose 2.2ml for 24 hours and keeps everything stable.
