Quick Overview

Why does BRS recommend this?


The BRS 1.1 mL dosing pump is a very cost effective yet long lasting stand-alone dosing pump for trace elements and 2 part.  By hooking the pump up to a simple timer or aquarium controller they can be one of the most inexpensive ways to get an automated 2 part dosing system.   With their peristaltic design they will not back siphon with extremely accurate flow rates.


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

Product Questions

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.
Answer by: Bulk Reef Supply on Jan 15, 2015 5:28:00 PM
Great question! This pump is self priming, meaning you will not need to have the liquid above the pump. It provides a 20ft max head pressure.

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.
Answer by: Bulk Reef Supply on Jan 17, 2014 5:38:00 PM
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).

Answer by: Bulk Reef Supply on Feb 6, 2014 6:58:00 AM
My BRS dosing pump is working, but is not drawing solution from a 1 gal jug. What could be the reason for this? The jug is about half full and has a small air hole. Thanks
Question by: Anna on Apr 25, 2016 12:29:00 PM
Great question!
Most likely the issue is the tubing leading to the pump or the tubing inside of the pump is not air tight which allows the suction to break. You will want to inspect all tubing to ensure there is not air leaks for the siphon to break.
Answer by: Connor (Admin) on Apr 27, 2016 2:57:00 PM
what is the average life span of this pump and are the critical parts replaceable
Question by: vinny on Apr 25, 2016 8:50:00 PM
Great question!
These will last quite a while from 3 years and up without over use or abuse. They come with a one year warranty. Currently there are replaceable tubing however no electronic or mounting replacements.

Can this dosing pump be used to dose frozen food?
Question by: June on Mar 17, 2016 11:15:00 AM
Great question!
It certainly can however depending on the placement of the tubing if you are not using a specially DIY fridge to keep the tubing from sitting in the open the pump will draw food and as it stops the food that remains in the tubing will begin to rot and cause big issues. You will want to checkout some forum posts on building a fridge with a venturi to grab the food into a separate feed pump which circulates in the fridge keeping the frozen food cooled until it enters the tank. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 18, 2016 9:50:00 AM
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
Can this doser be used safely with Red Sea NOPOX?
Question by: Randy on Jan 14, 2016 8:35:00 PM
Great question!
This can be used with a timer to dose a small amount of NoPox throughout the day. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Jan 15, 2016 3:47:00 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
I bought these pumps with my reefkeeper lite, and I thought I would be able to connect them to it. It says not to, so what should I do?
Thanks.
Question by: Lukasson on Jan 29, 2016 7:42:00 PM
Hey there!
The dosing pump can be used with the reefkeeper as long as it is plugged into the relay outlet which has the ability to power the pumps. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Feb 9, 2016 4:00:00 PM
One of my dosers suddenly stopped working/rotating. I want to start from scratch- How do I "prime" the doser? I'm starting them over from scratch and don't have the instructions anymore.
Question by: Lisa on Jan 31, 2016 6:15:00 PM
Great question!
To prime the pumps you will simply attach the full amount of tubing from the container to the aquarium, You will then turn the pump on and allow it to fill with the solution. Once the solution starts coming out the other side you will want to run it for a few minutes to remove and air gaps. Keep in mind this can take some time and we recommend pumping it into another container instead of the tank itself.
Answer by: Connor (Admin) on Feb 10, 2016 3:46:00 PM
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 :)
Answer by: Bulk Reef Supply on Aug 21, 2014 7:59:00 AM
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
After calibration one of my pumps doses 1.9ml per minute and the other 1.7ml per minute, not the 1.1 as indicated. Looks like others have had similar findings. Is this variability expected with this product?
Question by: Doug Windey on Jan 23, 2016 10:47:00 PM
Great question!
Variability is to be expected with dosing pumps and the 1.1 mL is an average rating of the pumps. Overall it is best to measure the flow to find the accurate dosage depending on power, lifespan of the tubing and several other factors. Often remeasuring once a year will help to keep the flow accurate.
Answer by: Connor (Admin) on Feb 3, 2016 11:17:00 AM
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!

  • Excellent dosing pump By Carlos Vicente on 4/22/2016

    I already have 5 of these pumps in my setup, that says it all. Three of them over a year old 7 cycles 24/7 no problem whatsoever.
  • works very well By peter on 3/10/2016

    purchased best timer on amazon and works great
  • make sure you calibrate By Jacifer on 2/26/2016

    Automating my calcium and alkalinity has been a life saver! No more trying to explain to house sitters how and why to dose. Just make sure you calibrate the pumps as directed. Each one differs slightly from the 1.1ml as described
  • Awesome By Rick on 2/26/2016

    Great doser. Plan to add more to the tank.
  • Good dosing pumps By wayfastwhytey on 2/5/2016

    I bought 2 of these and they work pretty good. The flow on them is off from the advertised 1.1 though, as both mine flow around 2 ml a min, no biggie.
  • Great pump at a sweet price By Plomanto on 2/4/2016

    This is my third pump from BRS. I love them work great and the three match up extremely well with each other
  • solid doser By always fishing on 1/31/2016

    works well flow rate depends on length of hose so do the 10 minute dose to get an accurate measurement and then your good to go
  • Pump Works Great - Fittings have Problems By Lawrence on 11/5/2015

    I recently bought the BRS 2 Part Doser. The pump itself works great. It is dead quiet and delivers the solution at a steady rate of 2ml/min (follow instructions about calibrating the pump!). The problems I have had were 2-fold. First the mount for the pump is mediocre. The screws for it are mounting in drywall. If you mount into wood you to get your own flat-head screws. The mount is flimsy and I have yet to get the pump to slide onto it securely. The issue is with the mur-lok bulkhead fitting for putting a straight tube into the solution jug and attaching it to the pump intake tubing. It continually leaked air despite a number of attempted fixes. I finally scrapped for another solution. I can NOT recommend the mur-lok bulkhead fitting.
  • Great Product! By William on 9/6/2015

    Works just like they say they will. My corals have opened up more since I started using this with the BRS 2 part.
  • Great 2 Part Doser By John on 6/14/2015

    I bought 2 of these to replace an all in one unit similar to the Bubble Magus. These things are huge compared to the pumps in my old unit. Both pumps have a flow rate of 1.67ml per minute, not the 1.1ml as advertised. I hooked them up to Reef Keeper Lite and they are working great so far.
  • 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
