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.
It sure is. You can find the replacement tubes at the link below:
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.
Input/output tubing are the same and both are 1/4" though its a compression fitting so its fairly forgiving if your close.
This stuff will do the trick just fine (most use clear).
While this pump is very consistent in dosing, due to the rotational cycle, there tend to be natural pauses as the rollerblocks take turns in compressing the tubing, which results in variation in fluid dosing speed during a single 1 minute rotation. As a result, when run for full minute cycles, you'll see good consistency, but it will not be very effective at running for less than a minute when trying to dose very small amounts of fluid. For this, we would normally recommend a pump with a high precision stepper motor or at the very least a dosing pump with more than two rollerblocks, such as the Drew's Doser, in order to reduce the momentary pauses during rotation.
Have a great day!
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.
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.
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!
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.
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!
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?
It measures 4" x 3.5" x 4" Tall
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!
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.
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!
These pumps can pump up to 20ft of head pressure. Going up from the stand to the tank would be no problem at all!
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 :)
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 :)
The physical motor will last a long time and as long as it is spinning it will work well. The surgical tubing inside however may wear down and crack. If the pump is ever not able to draw liquid up you will want to inspect and replace the tubing inside. Additionally over time this tubing will stretch and change the amount of liquid dosed and measurement will need to be taken to test how much it is dosing. This can be a s simple as taking the tubing out of the tank, turning the doser on for 10 minutes and measuring how much liquid is dosed in 10 minutes.
The 1.1 mL Dosing pumps will need to be physically plugged into an outlet to turn on. With some aquarium controllers they use different types of outlets to turn the outlet on and off. TRIAC switches can switch power very quickly and silent, where a relayed outlet makes a clicking noise and takes about a half a second to react. TRIAC outlets can have a hard time detecting power and turning the dosers and other low power consumption items on and off reliably, where the relayed outlets are very reliable for almost all items. If you don’t have an aquarium controller it shouldn’t be a concern since most digital and analog timers are going to be relay driven. If you are using an aquarium controller just refer to the controller’s manual to know what outlets are TRIAC and which are relayed.
That isn't a problem at all :-)
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.
That won't be a problem. The pump shouldn't have any issue pulling solution up anywhere within a normal sized aquarium stand.
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.
Old Reliable. By Robert on 1/9/2017Robert would recommend this product to a friendI have had my pumps going on 5 years now. I use them to dose fertilizers for planted tank. Still going strong with original tubing. I only dose 1 ml per day. on each pump. Would definitely recommend.
Calibrate first. Closer to 2ml/minute rate By Biggen on 1/4/2017Biggen would recommend this product to a friendThe pump is advertised as 1.1ml/minute dosing rate. However, in reality, mine is double that. I tested multiple 10 minute intervals and, each time, it doses about 1.9ml/minute or 19ml per 10 minute interval. This isn't big deal but I think they should change the product description to reflect its true dosing rate. I rate it 4 out of 5 stars because of this.
I'm happy with them By Dave on 12/11/2016Dave would recommend this product to a friendI use it with my Reef Keeper Plus and BRS soda ash and CaCl and I've been able to hit my targets easily.
Perfect By Karen on 10/29/2016Karen would recommend this product to a friendThis made my dosing life easier, as I'd often forget to dose! It is also handy when I go away for a few days as well. It's small and easy to hide away in the the cabinet.
Great dosing pump By Brad on 10/17/2016Brad would recommend this product to a friendI ordered the 2 part kit that came with 2 pumps. The system Work's flawlessly to deliver the alkalinity and calcium to my tank. Beats doing it by hand even though I only have a 90 gallon tank.
1.8ml pumps By Ramon on 10/15/2016Ramon would recommend this product to a friendI bought 2 of these for 2 part dosing. They make a loud click when first turned on. Which is nice so I know it's on. After that, I don't hear them over the return pump.
It's been working great controlled by Apex for the last 5 months.
Like others have said, they dose more 1.1 ml per minute, both mine were 1.8 ml.
Makes life easy. By Rich on 9/29/2016Rich would recommend this product to a friendI had been dosing kalk using a container and gravity to feed my tank. While it did work, there were times it would stop. Using the 2 part doser insures that a controlled amount is put in the tank each day.
Makes dosing so much easier By Paul on 7/17/2016Paul wouldn't recommend this product to a friendI recently installed 2 of these on my tank. They have eliminated the need for daily dosing. I have them running 8 times / day and so far, so great! One note is to make sure you follow the instructions regarding calibration. Mine both deliver roughly 2ml / minute as opposed to the 1.1 listed. No big deal, but you do need to know how much you are dosing. Great product!
Awesome By Darrin on 7/4/2016Darrin would recommend this product to a friendhad 3 of thew for 2 to 3 years still working great
Great reliable pump once its setup right. By Chris on 6/23/2016Chris would recommend this product to a friendThese are great pumps and the extremely slow speed makes them great for very gradual dosing using a controller. I used these pumps in conjunction with the 1/4 bulkhead, acrylic tubing, and the space saving dosing containers for my 2-part solution. I have to say the pumps worked as advertised. I had a bit of trouble getting the bulkheads to not leak but after redoing the connections and being very careful to cut the acrylic and tubing square as well and ensuring everything was fully seated its working well. One thing related to the pump was that I had a completely downhill run on the output side of the pump which while overall dosing volume was fine it made the dosing somewhat inaccurate for daily testing. This was easily solved with a slight uphill section just before the output in the sump. Since the pump is constantly pinching the tubing the problem was a simple draining issue and not a siphon issue so it was an easy fix.
great By bill on 5/25/2016bill would recommend this product to a friendlet the the doser do the work for me..
Excellent dosing pump By Carlos Vicente on 4/22/2016Carlos Vicente would recommend this product to a friendI 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.
